Support contact:
HPE recommends using the Maintenance Window functionality within the HPE InfoSight portal to inform HPE Support of
upcoming maintenance windows.
Refer to https://infosight.hpe.com/dashboards/nimble/wellness/maintenance-windows for more information.
You can disable automated support case generation during planned maintenance from the Manage Maintenance Windows
page. After a maintenance window is set, no further communication with HPE Support is required.
Important:
Controllers may only be serviced in Standby mode. Never remove a controller running in Active mode. You do not
have to shut down the array or expansion shelf to replace or add a PCIe card. The storage array can function with
one active controller while the PCIe card is added on the standby controller.
Note:
While a controller is removed (one at a time), the internal temperature of the chassis can rise to critical levels.
Keep installation time to no more than 15 minutes per controller.
If you are adding an SCM card, slot 2 is recommended.
If you are adding a new HBA, or moving an existing HBA to a different slot in the controller, you may need to run
an update on the HBA to reconfigure it in the system.
If you are upgrading an HBA, validate that the new WWPNs shown in the NimbleOS GUI have been added to the
switch fabric zoning configuration. For port zoning, additional configuration is not required. For WWN zoning, the
zoning configuration must be updated with the new WWPNs of the upgraded HBA.
Procedure
1. Identify and halt the controller that is in Standby mode.
a) Log in to the array using the CLI.
b) Determine which controller is in Standby or Unknown mode.
ctrlr --list --array array_name
c) Halt the standby controller.
halt --array array_name --controller {A | B}
2. Physically remove the standby controller.
a) Label all cables to ensure proper recabling later, then remove them from the controller.
b) Pinch the controller release lever catch to release the controller release lever.
c) Firmly pull the controller release lever until the controller slides out of the chassis. Then place the controller on a flat
surface.
