System BIOS reports that system was reset due to timeout from operating system (OS) watchdog timer
Description
On systems when: Software Raid Dell PowerEdge RAID Controller S150/S140 is enabled
8
Fixes
SLES 15 SP3 installed OS watchdog timer is enabled in system BIOS The system
BIOS reports that system was reset due to timeout from watchdog timer when the
system is rebooted gracefully.
Following message is displayed in BIOS Power On Self Test (POST):
UEFI0082: The system was reset due to a timeout from the watchdog timer. Check
the System Event Log (SEL) or crash dumps from Operating System to identify
the source that triggered the watchdog timer reset. Update the firmware or
driver for the identified device.
Workaround
The message can be ignored as the system reboots gracefully. The issue can be worked around by disabling OS watchdog timer in system BIOS.
Solution
The issue is resolved in SUSE Linux Enterprise Server 15 Service Pack 3 maintenance update kernel version kernel-default-5.3.18-150300.59.98.1.

Zoning changes on SFSS not reflected in the host
Description Workaround Solution Applies to
NVMe-oF Transport Control Protocol (TCP) zoning changes made on Dell
SmartFabric Storage Software (SFSS) that remove access to I/O controllers on
NVMe subsystem are not reflected in the host.
The host service stacd, a part of the nvme-stas package, automatically
connects to the I/O controllers returned in response to the get log page
command . Each I/O controller is represented as a Discovery Log Page Entry
(DLPE) in response to the get log page command. When a zoning change is made
on SFSS to remove access to one or more I/O controllers, the change is ignored
and is not applied by the stacd service. stacd continues to connect to the I/O
controllers returned by the existing DLPEs.
Disconnect relevant controllers: 1. Remove all connections between the host
and subsystem:
nvme disconnect -n
2. Remove only a single connection between the host and subsystem:
nvme disconnect -d
The issue is resolved in nvme-stas 1.1.6. If the desired behavior is to
disconnect I/O when an associated zoning change is implemented, the following
changes are needed: # vi /etc/stas/stacd.conf sticky-connections=disabled #
systemctl reload stacd SUSE Linux Enterprise Server 15 Service Pack 4
The version field in the output of the modinfo command for certain networking drivers is null
Description

MD RAID layer is not notified of the surprise removal of Samsung NVMe devices
Description
When a virtual disk is created on the MD RAID layer using a Samsung NVMe device, the MD RAID layer is not notified of the surprise removal of the NVMe drive. The output of the mdadm -D command displays an incorrect status of the MD RAID virtual disk (VD). The issue is observed on Dell Express Flash PM1725a, PM1725b, Enterprise NVMe Agnostic (AGN) devices. The array status reporting is incorrect. When I/O operations are performed, I/O errors are observed as expected and the file-system changes to read-only.
Cause
The issue is related to handling devices which showcase multipath capability.

PowerEdge servers with the AMD Rome processor fail to detect an NVMe drive after multiple hot plugs
Description
Cause Workaround
The PowerEdge servers with the AMD Rome processor fail to detect an NVMe drive
after multiple hot plugs.
Issue in pciehp driver.
NOTE: The output of each command varies based on your system configuration.
Follow the steps: 1. Identify the parent device to which the NVMe device is connected using the following command:
lspci -t
-+-[0000:e0]-+-00.0
|
+-00.2
|
+-01.0
|
+-02.0
|
+-03.0
|
+-03.1-[e2]—-00.0
From the above snippet, the device e2:00.0 is the NVMe device and the device
e0:03.1 is the parent device. The parent device is used for the steps that are
described subsequently. 2. Read the Slot Status Register in the PCI Express
Capability structure by running the following command:
setpci -s e0:03.1 CAP_EXP+0x1a.w
Output: 0148 (value returned) 3. Clear the event bits that are impacted by
running the following command:
setpci -s e0:03.1 CAP_EXP+0x1a.w=0x0108

Fixes
4. Re-read the Slot Status Register to confirm that event bits are cleared by running the following command:
setpci -s e0:03.1 CAP_EXP+0x1a.w
Output: 0040 (value returned) 5. Unplug the drive and then plug-in the drive after clearing the event bits.

Component updates in systems with iSM installed on SUSE Linux Enterprise Server 15 SP1 operating system generates watchdog timer expired messages
Description
Firmware updates performed using Linux DUP files with iSM running in the background generates watchdog timer expired events in the Lifecycle Controller log files.
Cause
Latest updates in the ipmi driver allow ipmi driver to unload, though the /dev/ipmi is in use by user space tools. Firmware DUPs try reloading the ipmi driver while running. Running Linux DUPs breaks the iSM connection with iDRAC and causes iDRAC to register the connection break after a timeout. After the firmware update is completed, the iSM connection with iDRAC is reestablished.
Solution
The issue is resolved in SUSE Linux Enterprise Server 15 SP2, SUSE Linux Enterprise Server 15 SP1 Maintenance Update Kernel 4.12.14-197.34.1 version and later. For more information, see SUSE Linux Enterprise Server Knowledge Base article 000019602.

Identifying the series of your PowerEdge servers
The PowerEdge series of servers are divided into different categories based on
their configuration. They are referred as YX2X, YX3X, YX4X, YX4XX, or YX5XX
series of servers. The structure of the naming convention is described below:
The letter Y denotes the character in the server model number. The character
denotes the form factor of the server. The form factors are listed below:
C- Cloud F- Flexible M or MX- Modular R- Rack T- Tower
The letter X denotes the numbers in the server model number. The number
denotes multiple characteristics about the server. They are listed as
follows:.
The first digit (X) denotes the value stream or class of the server. 1-5–iDRAC
basic 6-9–iDRAC Express
The second digit denotes the series of the server. It is retained in the
server naming convention and does not replace the letter X. 0–series 10
1–series 11 2–series 12 3–series 13 4–series 14 5–series 15
The last digit (X) always denotes the make of the processor as described
below: 0-Intel 5-AMD NOTE: For servers that use an AMD processor, the model
number is made up of four digits instead of three. The third digit (X) denotes
the number of processor sockets that the series of server supports.
