Getting started
Front-Accessible NVMe Storage (FANS) is a utility application for NVMe
Enclosure units. FANS provide a unified interface for drive status monitoring,
drive ejection, RAID information for any inserted NVMe® drives, and
configurable notifications of drive events.
NOTE : RAID is defined as a redundant array of independent disks or a
redundant array of inexpensive disks.
Supported operating systems
The following table describes the operating systems supported by FANS.
Table 1-1 FANS Compatibility

- Run the following command from a terminal: sudo system ctl start hp-fans.
Quitting FANS
This chapter describes how to quit FANS manually.
Background service
To quit the FANS service manually, follow the steps for your operating
system.
Windows
Follow these steps to quit the FANS service manually in Windows.
- From the services app, find the service. For more information, see Background service on page 2.
- Right-click the service and select Stop. You can also left-click the service to select it and select Stop Services in the services app.

- To manually quit the client, right-click the FANS icon in the system tray, and then select Quit. This action stops the FANS client process and removes the FANS icon from the system tray.
FANS user interface
This chapter describes the elements in the FANS user interface that monitor and control the utility. The following diagram and table illustrate these elements.
Table 4-1 FANS user interface
| Number | Element | Description |
|---|---|---|
| 1 | Refresh button | This button starts a rescan of the NVMe Enclosure and any |
RAIDs that include drives inside the QX enclosure. FANS usually detects
changes dynamically, but in case it ever stalls, use this button.
2| Pop-out & anchor-back button| If FANS is in the system tray, this button
opens FANS in its own window. This feature allows you to interact with other
applications without having the FANS user interface automatically hide. Use
this button to drag the FANS window around (resizing is not available). If
FANS is already in its own window, use this button to anchor the app back to
the system tray.
3| Notification settings| Use the settings tab to customize the notifications
that you receive from the FANS application.
Number| Element| Description
---|---|---
4| About & help page| The about page includes the version number of the FANS
application and a link to this user guide.
5| Drive array tile| Displays information for a drive array, which is an array
of physical drives where one or more RAID volumes can exist. RAID volume
refers to the storage partition created on the array, or some subset of it.
NOTE: The more general term RAID refers to the combined concept of drive arrays and RAID volumes. Some RAID providers might not distinguish between drive arrays and RAID volumes. They might only consider RAID as a concept.
6| Drive array identifier| This label assigns each drive array a number that identifies it.
NOTE: In Windows Storage Spaces, a drive array is a storage pool.
7| Drive array status indicator| No physical LED indicates the drive array status. The drive array status has only two colors. Green indicates an array with healthy RAID volumes, and red indicates that at least one of the RAID volumes has encountered a RAID fault. This status includes warnings and errors that result in an unhealthy status. You can hover over the status indicator to see a tool tip that shows the status as text.
NOTE: RAID faults are resolved through the RAID provider. FANS monitors the status of RAID volumes but you cannot use it to resolve issues.
8| Drive array/RAID provider| This element shows the software that provides
the RAID capability. Some examples of such software include VROC, Windows
Storage Spaces, Linux MD, and Linux LVM.
9| RAID volume| The first line in the RAID volume box lists the RAID volume
label. The second line lists the RAID volume type, which signifies what kind
of data redundancy the RAID volume has. For example, RAID 1 is a mirror-
redundancy.
NOTE: In Windows Storage Spaces, the RAID volume is a storage space.
10| Model numbers of RAID drives| This element displays the model number of
each drive in the RAID.
11| Slot numbers of RAID drives| This element displays the slot number of each
front NVMe drive in the RAID. For drives that are not front NVMe drives, the
message Internal is shown instead of the slot number.
12| Front NVMe drive tile| This element displays information about the drive,
such as the eject button for the drive. The position of this
tile correlates to the position of the drive in the NVMe Enclosure. For example, a drive in the top right of the NVMe Enclosure displays in the top- right tile of this application.
13| Drive model number| This element displays the model number of the drive in
the slot.
Number| Element| Description
---|---|---
14| Drive tile slot number| This element displays the slot number of each
front NVMe drive. In the NVMe Enclosure the top-left slot is numbered 1, the
top-right is slot 2, the bottom-left is slot 3, and the bottom-right is slot
4. In the other NVMe Enclosure, the left slot is slot 1, and the right slot is
slot 2.
15| Drive status indicator| The colored circle represents the status of the
physical LED on the NVMe Enclosure. The status circle in the user interface is
the same color as the physical LED. The message to the left of the status
circle also shows the status.
Status colors key:
● Green: Healthy. The status message shows Drive is Present.
● White: Ejected. The status message shows Safe to Remove Drive.
● Red: Warning or error. Includes SMART critical warnings. The status message shows Drive Warning if there is a warning, or Drive Unhealthy for more serious errors.
16| Left tile: Volume letter (Windows) / Mountpoint (Linux)
Right tile: Drive array label
| On Windows, if the drive is formatted with volumes, this element displays those volumes’ drive letters. On Linux, if the drive has mounted partitions, those mountpoints are displayed. On either OS, if the drive is a member
of a drive array, this element displays that drive array number. If the drive is not formatted with a volume or a member of a drive array, this label is blank.
17| Eject button| Selecting this button ejects the drive, and makes it safe to
remove. Always select this button before removing a drive to prevent loss of
data. You are not able to eject your OS drive, or any drive in a RAID. The
former would instantly crash your machine, and the latter would degrade RAID
redundancy or data availability.
18| System tray icon| This element is the icon for FANS. When the application
is not open, clicking this icon opens the user interface of the app. The icon
has a status circle that reflects the status of the front NVMe drives and
RAIDs that the app monitors. If every drive and drive array is healthy, the
status circle on the icon is green. If at least one of the drives or drive
arrays has a warning or is unhealthy, the status circle is red.
