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 component. The storage array can function
with one active controller while the component is added on the standby controller.
•
Before removing a controller, address any power supply issues in the peer controller if the power supplies do not
show proper operational status (green LED). For HPE Alletra 6030 and 6050 arrays with 800 W power supplies,
this precaution is critical.
Procedure
1. Prepare the controller for removal.
a) Log in to the array using the CLI.
b) Determine whether the controller is in Standby mode.
ctrlr --list --array array_name
c) If the controller is in Active mode, perform a manual failover.
failover --array array_name
d) Verify that the manual failover placed the controller in Standby mode.
ctrlr --list--array array_name
e) Halt the controller.
halt --array array_name --controller {A | B}
2. Remove the controller
a) Disconnect the power cords from the two controller power supplies.
b) Label all cables to ensure proper recabling later, then remove them from the controller.
c) Loosen the left and right thumbscrews to free the controller release levers from the controller.

d) Pull the controller release levers down until they stop. The controller ejects slightly from the chassis.
e) Supporting the weight of the controller, pull the controller release levers to slide the controller out of the chassis. Then
place the controller on a flat surface.
3. Replace the failed fan with the new fan.
a) Locate the failed fan.
