Physical Disks
NOTE: The physical disks in a virtual disk must be of the same drive type
(HDD, SSD or NVMe PCIe SSD). For example, you cannot mix an HDD and an NVMe
PCIe SSD in the same virtual disk. NOTE: The drive activity LED blinks
continuously while there are background tasks running on the disk.
Topics:
· Physical disk features
Physical disk features
Physical disk roaming
Physical disk roaming is moving the physical disks from one cable connection
or backplane slot to another on the same controller. The controller
automatically recognizes the relocated physical disks and logically places
them in the virtual disks, which are part of the disk group. You can perform
disk roaming only when the system is turned off.
CAUTION: Do not attempt disk roaming during online capacity expansion (OCE).
This causes loss of the virtual disk.
Physical disk hot-swapping
NOTE: To check if the backplane supports hot swapping, see your system
documentation. Hot-swapping is the manual replacement of a disk while the PERC
S140 is online and performing its normal functions. The following requirements
must be met before hot-swapping a physical disk: The system backplane or
enclosure must support hot swapping for the PERC S140. The replacement disk
must be of the same protocol and disk technology. For example, only a SATA
hard drive can replace a
SATA hard drive and only a SATA SSD can replace a SATA SSD. NOTE: Disk hot-
swapping is not supported in UEFI HII; it is supported only in OS mode. NOTE:
When hot-swapping a physical disk, ensure that the new disk is of equal or
greater capacity to the physical disk that is being replaced.
Physical disk power management
Power management is a power-saving feature of the PERC S140. This feature
supports power management of SATA hard drives (HDD) by using Extended Power
Conditions (EPC). The EPC feature set provides the host with additional
methods to control the power condition of a device.
Physical disk failure detection
Physical disk failure is detected and the controller automatically rebuilds a
new physical disk assigned as a hot spare. NOTE: Refer to drive mixing
restrictions for rebuilding.
12
Physical Disks
Mirror rebuilding
A RAID mirror configuration can be rebuilt after a new physical disk is
inserted and the physical disk is designated as a hot spare. NOTE: The system
does not have to be rebooted.
Fault tolerance
The following fault tolerance features are available with the PERC S140: If
one side of a RAID 1 (mirror) fails, data can be rebuilt by using the physical
disk on the other side of the mirror.
Physical disk failure detection (automatic). Virtual disk rebuild using hot
spares (automatic, if the hot spare is configured for this feature). Parity
generation and checking (RAID 5 only). Hot-swap manual replacement of a
physical disk without rebooting the system (only for systems with a backplane
that
allows hot-swapping).
If a physical disk in RAID 5 fails, parity data exists on the remaining
physical disks, which can be used to restore the data to a new replacement
physical disk configured as a hot spare.
If a physical disk fails in RAID 10, the virtual disk remains functional and
data is read from the surviving mirrored physical disk(s). A single disk
failure in each mirrored set can be sustained, depending on how the mirrored
set fails.
Self-Monitoring And Reporting Technology
The Self-Monitoring and Reporting Technology (SMART) feature monitors certain
physical aspects of all motors, heads, and physical disk electronics to help
detect predictable physical disk failures. Data on SMART compliant physical
disks can be monitored to identify changes in values and determine whether the
values are within threshold limits. Many mechanical and electrical failures
display some degradation in performance before failure.
A SMART failure is also referred to as a predicted failure. There are numerous
factors that are predicted physical disk failures, such as a bearing failure,
a broken read/write head, and changes in spin-up rate. In addition, there are
factors related to read/write surface failure, such as seek error rate and
excessive bad sectors.
NOTE: For detailed information on SCSI interface specifications, see t10.org,
and for detailed information on SATA interface specifications, see t13.org.
Native Command Queuing
Native Command Queuing (NCQ) is a command protocol used by SATA physical disks
supported on the S140 controller. NCQ allows the host to provide multiple
input/output requests to a disk simultaneously. The disk decides the order to
process the commands to achieve maximum performance.
NVMe PCIe SSD support
S140 supports the NVMe PCIe SSD-including the NVMe PCIe SSD 2.5-inch Small
Form Factor (SFF) and NVMe PCIe SSD Adapter.
The S140 allows the NVMe PCIe SSD 2.5 inch SFF and the NVMe PCIe SSD adapter
in a RAID configuration. The NVMe PCIe SSDs supports volume, RAID 0, RAID 1,
RAID 5, and RAID 10. S140 also supports Prepare to remove feature to remove
Non-RAID NVMe volume from the Dell open manage console.
The recommended minimum version to support the NVMe drives is listed in the
following table:

NOTE: Hot removal or hot insertion of the NVMe PCIe SSDs in UEFI or preboot
mode is not supported. In the operating system environment, hot-swapping two
or more NVMe PCIe SSDs simultaneously is not supported.
NOTE: Mixing of SATA drives and NVMe PCIe SSDs in a virtual disk is not
supported.
NOTE: Ensure that you use only the S140 UEFI configuration utility to
configure the NVMe PCIe SSDs during preboot.
NOTE: In UEFI HII mode, you can use the NVMe PCIe SSD option on the Device
Settings page to view NVMe physical disk properties and perform blink/unblink
operations.
NOTE: RAID configuration and boot from NVMe virtual disk is supported only in
UEFI boot mode.
NOTE: RAID configuration using Option ROM (OPROM) is not supported on systems with the NVMe PCIe SSD.
Physical disk write cache policy for SATA drives
The physical disk write cache policy feature enables the disk to cache the
data first, and then the cached data is written to the storage device in the
background. For more information about managing the physical disk write cache
policy, see Managing the physical disk write cache policy for SATA drives.
NOTE: You can use UEFI or Option ROM (OPROM) to configure the physical disk
write cache policy.
NOTE: You cannot configure a physical disk write cache policy on a non-RAID
disk.
NOTE: Linux RAID does not support configuring physical disk write cache
policy, or virtual disk write cache policy.
Linux RAID
Linux operating systems supported: Red Hat Enterprise Linux 8.0 and above SUSE
Linux Enterprise Server version 12 SP2 and above The Linux RAID feature is
supported on all PowerEdge 14th generation systems. You can use Linux RAID to
protect data across multiple devices. The S140 configuration utility supports
configuring RAID 1 virtual disk in UEFI mode. The Linux operating system can
be installed on that virtual disk, and once the system boots to the Linux
environment, the Linux native RAID driver manages the virtual disk. For
information about configuring Linux RAID, see Configuring Linux RAID.
NOTE: Ensure that your system has the latest BIOS firmware. You can download
the latest BIOS firmware from https:// www.dell.com/support.
NOTE: Ensure that you use only the S140 UEFI configuration utility to
configure Linux RAID feature during pre-boot.
NOTE: Ensure that the boot virtual disks are configured in RAID 1, using two
physical disks of identical drive type (HDD or SSD) and sector size. However,
you can also configure nonboot virtual disks in any of the supported RAID
levels in the Linux operating system.

Virtual Disks
A logical grouping of physical disks attached to a PERC S140 allows you to
create multiple virtual disks of the same RAID levels, without exceeding a
maximum of 30 virtual disks. The PERC S140 controller allows: Creating virtual
disks of different RAID levels on a S140 controller.
NOTE: Ensure that you do not mix RAID levels on the same physical disks.
Building different virtual disks with different characteristics for different
applications. Creating virtual disks from a mix of NVMe PCIe SSD 2.5-inch SFFs
and NVMe PCIe SSD adapters. The PERC S140 controller does not allow: Creating
a virtual disk from a mix of different types of physical disks. For example, a
RAID 10 virtual disk cannot be created
from two SATA HDD physical disks and a SATA SSD physical disk. All of the
physical disks must be of the same drive type (HDD/SSD/NVMe PCIe SSDs).
Selecting a physical disk as a dedicated hot spare if the physical disk is a
different type from the physical disk of the virtual disks. A virtual disk
refers to data storage which a controller creates using one or more physical
disks.
NOTE: A virtual disk can be created from several physical disks; the operating
system considers it a single disk.
The capacity of a virtual disk can be expanded online for any RAID level
without rebooting the operating system. NOTE: If the boot VD is spanned across
different SATA controllers, then Windows Hardware Quality Labs testing (WHQL),
DF – Reinstall with I/O Before and After (Reliability) fails in a server
having two SATA controllers.

Virtual disk features
TRIM for SATA SSDs
The TRIM command allows an operating system to delete a block of data that is
no longer considered in use from the SATA SSDs. TRIM resolves the Write
Amplification issue for supported operating systems. When an operating system
deletes a file, the file is marked for deletion in the file system, but the
contents on the disk are not actually erased. As a result, the SSDs do not
know that the Logical Block Addressing (LBA) file previously occupied can be
erased. With the introduction of TRIM, when a file is deleted, the operating
system sends a TRIM command along with the LBAs that do not contain valid
data.
NOTE: The TRIM feature is supported only on pass-through SSDs.
NOTE: The TRIM feature is not supported on NVMe PCIe SSDs.
To perform TRIM on the pass-through SSDs
1. Create a volume on a pass-through SSD drive. 2. In the Windows operating
system, navigate to the Defragmentation and Optimize Drive tool. 3. Select the
volume created on the pass-through SSD and click Optimize.
TRIM is applied.

Disk initialization
For physical disks, initialization writes metadata to the physical disk so
that the controller can use the physical disk.
Background Array Scan
Verifies and rectifies correctable media errors on mirror, volume, or parity
data for virtual disks. Background array scan (BAS) starts automatically after
a virtual disk is created while in the Windows operating system.
Checkpointing
Allows different types of checkpointing to resume at the last point following
a restart. After the system restarts, background checkpointing resumes at its
most recent checkpoint. Three types of checkpointing are available:
Consistency Check (CC) Background Initialization (BGI) Rebuild
Consistency check
Consistency check (CC) is a background operation that verifies and corrects
the mirror or parity data for fault-tolerant physical disks. It is recommended
that you periodically run a consistency check on the physical disks. By
default, CC corrects mirror or parity inconsistencies. After the data is
corrected, the data on the primary physical disk in a mirror set is assumed to
be the correct data and is written to the secondary physical disk mirror set.
The CC operation reports data inconsistencies through an event notification. A
CC cannot be user-initiated in the BIOS configuration utility, accessed using
Ctrl + R. However, CC can be initiated using OpenManage Server Administrator
Storage Management. For more information, see the OMSA user’s guide at
www.dell.com/openmanagemanuals.
Background initialization
Background initialization (BGI) of a redundant virtual disk creates the parity
data that allows the virtual disk to maintain its redundant data and survive a
physical disk failure. Similar to CC, BGI helps the controller to identify and
correct problems that might occur with the redundant data at a later time.
CAUTION: Data is lost if a physical disk fails before the completion of a BGI
operation. BGI allows a redundant virtual disk to be used immediately.
NOTE: Although a BGI is software-initiated from within the BIOS Configuration
Utility (accessible through Ctrl + R), the PERC S140 drivers must be loaded
before the BGI runs.
Automatic virtual disk rebuild
Rebuilds a redundant virtual disk automatically when a failure is detected if
a hot spare is assigned for this capability.
Virtual disk cache policies
NOTE: Configuring virtual disk cache policies on NVMe PCIe SSD is not
supported. The PERC S140 uses part of system memory for cache. It supports the
following cache options: Read Ahead/Write Back No Read Ahead/Write Back Read
Ahead/Write Through

NOTE: For more information about the physical disk write cache policy
behavior, see Troubleshooting your system
Virtual disk migration
The PERC S140 supports automatic virtual disk migration from one PERC S140 to
another. CAUTION: The virtual disk is lost if you perform a virtual disk
migration during an Online Capacity Expansion (OCE)/Reconfigure. NOTE: Back up
the virtual disk data before migrating virtual disks. NOTE: Ensure that all
physical disks that are part of the virtual disk are migrated. Virtual disks
in optimal and degraded states are automatically migrated. A virtual disk in
an offline state should not be migrated. NOTE: A bootable virtual disk cannot
be migrated between dissimilar system models.
NOTE: When you migrate virtual disks, ensure that you verify that the number
of virtual disks does not exceed 10.
Migrating a virtual disk
1. Turn off the system that contains the source controller. 2. Turn off the
target system if the system does not support hot swap of physical disks. 3.
Move the appropriate physical disks from the source controller to the target
controller in the target system.
Physical disks do not have to be inserted into the same slots in the target
system. 4. If the target system was turned off, turn on the system.
CAUTION: The BIOS Configuration Utility pauses, and prompts for action, for
the degraded virtual disk(s), if the “pause if degraded” option is enabled in
the BIOS Configuration Utility.
CAUTION: After the migration occurs, ensure that all of the physical disks
have been migrated and are present in the appropriate virtual disks.
Expanding virtual disk capacity
The capacity of a virtual disk can be expanded online by using the Online
Capacity Expansion/Reconfigure (OCE/Reconfigure). OCE/Reconfigure is a process
that allows you to add storage capacity to an existing virtual disk. In most
cases additional storage capacity can be added without taking the system
offline.
NOTE: If an additional physical disk is required and the system does not
support hot-swapping, the system must be turned off.
Virtual Disks
17
OCE/Reconfigure enables you to increase the total storage capacity of a
virtual disk by integrating unused storage with the virtual disk.
Data can be accessed while the physical disks are added (if a system has hot-
swap capability) and while data on the virtual disk is being redistributed.
For volume, RAID 1, and RAID 10, OCE/Reconfigure expands the virtual disk by
using the available space of the physical disks, which have been members of
the virtual disk. For RAID 0 and RAID 5, additional capacity can be attained
by adding physical disks to the virtual disk.
NOTE: There will be performance degradation until the capacity expansion is
completed.
NOTE: While the process of expanding the capacity of a virtual disk is in
progress, removing and reinserting the drive that is part of this virtual disk
is not supported. Users can reinsert the drive after the capacity expansion
process is completed.

BIOS Configuration Utility
The BIOS Configuration Utility, also known as Ctrl+R or Option ROM (OPROM), is
a storage management application integrated into the System BIOS accessible
using F2 during system boot, which configures and maintains RAID disk groups
and virtual disks on SATA drives. The BIOS Configuration Utility (Ctrl+R) is
independent of the operating system.
NOTE: Use the Ctrl+R for initial setup and disaster recovery. You can use
advanced features through OpenManage storage management applications.
NOTE: Configuring NVMe PCIe SSDs is not supported using the BIOS configuration utility.
NOTE: Ensure that you use only the S140 UEFI configuration utility to configure the NVMe PCIe SSDs during preboot. To enable RAID mode for NVMe PCIe SSDs, see Setting the NVMe PCIe SSDs to RAID mode .
NOTE: RAID configuration using OPROM is not supported on systems with the NVMe PCIe SSD.
The following sections provide information about using the Ctrl+R. For more
information, see the online help option by pressing F1 in the Ctrl+R.
The table below indicates the tasks that are supported or not supported by the
PERC S140 at the Ctrl+R.

Managing the hot spare disks
Manage Hot Spare(s) screen enables you to assign or unassign a global or
dedicated hot spare(s).
1. Enter the BIOS Configuration Utility. See Entering the BIOS configuration
utility. 2. In the Main Menu screen, use the arrow keys to select Manage Hot
Spare(s) and press
The Manage Hot Spare(s) screen display: global hot spare disks dedicated hot
spare disks
Assigning the global hot spare disks
A global hot spare disk is a backup physical disk that can be used by any
redundant virtual disk. It is not assigned (dedicated) to any specific virtual
disk. Virtual disks can typically be rebuilt by using a global spare disk, as
long as the global hot spare is not already part of the virtual disk and has
enough available capacity. Unlike a dedicated hot spare, a global hot spare
can be assigned at anytime, even while tasks are running on virtual disks.
NOTE: A hot spare can be created only if a physical disk is in the Ready or
Normal state in the Physical Disks field. If the physical disk is in the
Online state, the disk is being used by a virtual disk and cannot be selected
as a hot spare.
NOTE: If disk space is available in the global hot spare drive then a single
global hot spare can be assigned as a hot spare to multiple degraded virtual
drives. Therefore, it is possible for the same global hot spare to become part
of different degraded virtual drives that have different RAID levels. Perform
the following procedure to assign a global hot spare disk: 1. Enter the BIOS
Configuration utility. See Entering the BIOS configuration utility. 2. In the
Main Menu screen, select the Manage Hot Spare and press
Assigning the dedicated hot spare disks
A dedicated hot spare is a backup physical disk for the redundant virtual disk
to which it is assigned. The physical disk that is used as a dedicated hot
spare cannot be a member of an existing virtual disk. When the hot spare is
activated, it becomes the receptacle for the data from the failed physical
disk member of the volume, without interrupting the system or requiring your
intervention. A dedicated hot spare can be assigned to any redundant virtual
disk, and up to four hot spares can be assigned to a virtual disk. A dedicated
hot spare cannot be assigned while a task is running on the virtual disk.
24
BIOS Configuration Utility
NOTE: A virtual disk is marked Failed or Degraded if a physical disk reports a
Failed state, or if the SAS/SATA cable to the physical disk or power cable is

Troubleshooting your system
43
Performance degradation after disabling SATA physical disk write cache policy
Likely Cause:
Corrective Action:
Disk write operations can cause degradation in performance. To resolve this
issue, enable the physical disk write cache policy.
NOTE: Ensure that there is constant power supply to the system (A UPS is
recommended).
NOTE: If you create a virtual disk using Dell LifeCycle controller, then the
physical disk write cache policy is set to default. For more information about
the physical disk write cache policy behavior, see the Managing the physical
disk write cache policy for SATA drives section.
Unable to modify any feature settings in UEFI or OPROM
Likely cause:
Corrective Action:
You cannot modify the settings in UEFI or OPROM if the number of virtual disks
exceeds than 30.
To resolve this issue: 1. Start the operating system. 2. Use OpenManage to
ensure that the maximum number of virtual disks does not exceed 30.
Extra reboot during OS installation
Description Likely Cause:

Troubleshooting your system
WARNING- Found virtual disks that are degraded
This warning message is displayed when at least one virtual disk is in a
Degraded state and Pause if Degraded is set to ON at the BIOS Configuration
Utility Ctrl+R. The following message is displayed after the warning is
displayed: — Press Enter to continue, or Ctrl+R to enter setup —. Press Enter
to allow the operating system to continue with the boot sequence, or press
Ctrl+R to enter into the BIOS Configuration Utility Ctrl+R to investigate the
cause of the Degraded virtual disk. To investigate the cause, check for the
following: Whether a physical disk in the virtual disk has failed or has gone
offline. Check the status at the Physical Disks field. A
Degraded status depends on the RAID level of the virtual disk and the number
of physical disks that have failed: For a virtual disk at RAID 1 or RAID 5, a
single physical disk failure causes a Degraded status. For a virtual disk at
RAID 10, the failure of a physical disk in each of the mirror sets creates a
Degraded status for the RAID 10. The failure of two physical disks in the same
mirror set creates a Failed status for the RAID 10.
Whether the controller has failed due to a firmware failure or a component
failure. A failed controller causes a virtual disk not to boot.
For the virtual disk to recover from Degraded status, the failed physical disk
must be replaced and the virtual disk must be rebuilt using OpenManage Server
Administrator Storage Management. When the rebuild operation is completed, the
virtual disk status changes from Degraded to Ready. For a description of the
rebuild function, see Storage Management at dell.com/ support/manuals.
WARNING – Found virtual disks that are failed
This warning message is displayed when at least one virtual disk is in a
Failed state and Pause if Failed is set to ON at the BIOS Configuration

Troubleshooting your system
47
To investigate the cause, check for the following:
Whether the virtual disk is in Degraded status because one of the physical
disks of a RAID 1 or RAID 5 virtual disk has failed, or one of the physical
disks of a RAID 10 virtual disk has failed. Press Ctrl+R and verify if the
physical disks are offline or missing. Remove and replace a failed physical
disk. A second physical disk failure could cause a Degraded virtual disk to
change to Failed status.
Whether the virtual disk is in a Failed status because one or more of the
physical disks have failed. Press Ctrl+R and verify if the physical disks are
offline or missing. Remove and replace the failed physical disk or disks.

Stale partitions are listed on creating a virtual disk for Linux
Description: Solution
When a virtual disk is created using physical disks that were earlier used for
creating Linux virtual disk, some Linux partitions are present during
operating system installation.
When you create or delete a virtual disk, only the superblock metadata is
modified. The partition table of the virtual disk that is stored at logical
LBA-0 is not modified. Hence, when you re-create a virtual disk, the previous
partitions are still listed. During operating system installation, these
partitions can be deleted using the operating system
installer. To not list the partitions, if supported you can perform
cryptographic erase of the physical disk and
then create a virtual disk from the HII.
NOTE: Performing cryptographic erase deletes all the data on the physical
disks.
NOTE: In the Non RAID mode, if the NVMe disks (that were earlier used to
create VDs) are reused without deleting the metadata, the Linux Installer
still detects the VDs.
Rebuilding a virtual disk the global hot spare is not listed as online in HII or iDRAC
Description: Solution
After the rebuild of a virtual disk is completed using the global hot spare
the status of the disk is not listed as online, instead the status of the disk
is listed as ready.
This is an expected behavior. No action is required.
Virtual disk size in decimals is not supported while creating a VD
Likely Cause:
Corrective Action:
After entering the disk size value, changing the virtual disk size unit from
MB to GB or GB to TB and so on changes the disk size value.
It is recommended to select the virtual disk size unit before specifying the
disk size value.
Cannot create a virtual disk
If you are unable to create a virtual disk, check the following causes: 1. The
physical disk is not displayed. 2. Insufficient free space available on the
selected physical disks. 3. Incorrect number of physical disks selected for
the desired RAID level . 4. The desired physical disk is unavailable. 5. The
system already has a maximum of 30 virtual disks.
Troubleshooting your system
51
The physical disk is not displayed
This error might be because: 1. The controller cannot communicate with the
physical disks. 2. A cable might be loose or defective. 3. The physical disk
might be a SAS drive.
Re-seat the physical disks in the backplane and check their cables.
Insufficient free space available on the selected physical disks
There must be sufficient available free space on the physical disk used by the
virtual disk.
Incorrect number of physical disks selected for the desired RAID level
For details about RAID levels and the allowable number of physical disks used
with each RAID level, see understanding RAID levels in RAID Technology Guide
at dell.com/support/manuals.
The desired physical disk is unavailable
Determine whether the physical disk: 1. Is a dedicated hot spare and
unavailable for use in another virtual disk. 2. Is full or has insufficient
available capacity.
The system already has a maximum of 30 virtual disks
Delete unused virtual disks. CAUTION: Deleting a virtual disk destroys all
data on the virtual disk.
A virtual disk is in a degraded state
If the virtual disk is in a degraded state, check the following causes: 1. A
physical disk was removed. 2. Physical or mechanical problems with the
physical disk. 3. The virtual disk has lost redundancy. 4. Corrupted metadata
in the virtual disk.
A physical disk was removed
1. Install the original physical disk if it was inadvertently removed, or
replace it with a new or used physical disk. 2. Initialize a new physical
disk. Perform a Rescan for all physical disks that are replaced. 3. If the
physical disk was not removed, check that its cables are correctly installed.
Physical or mechanical problems with the physical disk
1. Determine if the physical disk in the virtual disk has failed. 2. If a
physical disk was recently removed and replaced, determine that it is
correctly positioned in the backplane. Check the
cable connections at the physical disk and at the system board. 3. Perform a
Rescan
52
Troubleshooting your system
The virtual disk has lost redundancy
One or more physical disks in the virtual disk may have failed, due to the
failed physical disk or disks, the virtual disk is no longer maintaining
redundant (mirrored or parity) data. The failure of an additional physical
disk results in lost data. 1. Replace the physical disk or disks. 2. Rebuild
the physical disk using Storage Management. See the applicable Storage
Management screen at www.dell.com/
manuals.
Corrupted metadata in the virtual disk
1. Delete the virtual disk that has the failed metadata. 2. Assign the
physical disk as a hot spare to rebuild a redundant virtual disk. 3. To create
a non-redundant virtual disk, delete and rebuilt the data on a virtual disk,
and restore the data from a backup
storage source.
Cannot assign a dedicated hot spare to a virtual disk
If you cannot assign a dedicated hot spare to a virtual disk, check the
following causes: 1. The RAID level does not allow a dedicated hot spare to be
created. 2. The designated physical disk does not have sufficient capacity to
be a dedicated hot spare. 3. The physical disk is already part of a virtual
disk. 4. The physical disk are of different types.
The RAID level does not allow a dedicated hot spare to be created
Hot spares cannot be created for Volume or RAID 0 virtual disks.
The designated physical disk does not have sufficient capacity to be a
dedicated hot spare
The capacity of the physical disk selected to be a dedicated hot spare must be
equal to or larger than the capacity of the smallest physical disk in the
virtual disk. For example, if the physical disk selected for a dedicated hot
spare is 160 GB, and the physical disks in the virtual disk are 80 GB, 160 GB,
and 500 GB, a dedicated hot spare can be assigned. That is because the
physical disk selected for the dedicated hot spare is larger than the smallest
(80 GB) physical disk in the virtual disk.
The physical disk is already part of a virtual disk
A dedicated hot spare cannot be assigned to another virtual disk.
The physical disk are of different types
The physical disk used as a dedicated hot spare must be the same type as the
physical disks that are already part of the virtual disk. For example, if a
virtual disk consists of SATA-II physical disks, the dedicated hot spare must
be a SATA-II physical disk.
Cannot create a global hot spare
If you cannot create a global hot spare, check the following causes: 1. There
are no empty physical disks available or the physical disks have not been
converted to RAID-capable disks. 2. The physical disk is already part of a
virtual disk. 3. The physical disk assigned as the global hot spare has
failed. 4. The physical disk assigned as the global hot spare is missing.
Troubleshooting your system
53
There are no empty physical disks available or the physical disks have not
been converted to RAID-capable disks
Install additional physical disks and convert them to a RAID-capable disk, If
existing physical disks are Non-RAID they need to be converted to RAID-capable
disks.
WARNING: When a physical disk is converted to RAID Capable disks, all data on
the physical disk is lost. NOTE: A physical disk with a Non-RAID status can be
converted to a RAID-Capable disk, if desired, but it is no longer Non-RAID
(Converting to RAID-Capable adds PERC S140 configuration information to the
physical disk).
The physical disk is already part of a virtual disk
A hot spare cannot be selected if it is already part of an existing virtual
disk.
The physical disk assigned as the global hot spare has failed
When prompted at system startup, press Ctrl+R to access the BIOS Configuration
Utility Ctrl+R. In the BIOS Configuration Utility Ctrl+R, select View Virtual
Disk Details and press Enter. Determine whether the physical disk that is
designated as the global hot spare has a status of Failed. 1. Check to see if
the physical disk is malfunctioning or is physically disconnected. 2. Select
another physical disk as the global hot spare.
The physical disk assigned as the global hot spare is missing
Check to see if the physical disk was removed from the backplane or cable
connection, or whether the cables from the controller to the physical disk are
disconnected or faulty.
Perform a rescan to verify that the physical disk is still missing.
A dedicated hot spare fails
If a dedicated hot spare fails, check the following causes: 1. The controller
cannot communicate with the hot spare. 2. The dedicated spare is not visible
in the BIOS Configuration Utility or is offline.
The controller cannot communicate with the hot spare
