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:
• Consult your RMA work order to verify on which controller to install the USB boot device
• Determine the state of the controllers and power supplies. 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 or Unknown 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 failover placed the controller in Standby mode.
ctrlr --list --array array_name
e) Halt the standby controller.
halt --array array_name --controller {A | B}
2. Remove the controller from the chassis.
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.
