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.
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.
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.
