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.
The expansion shelf serial number is on the system information label at the rear of the chassis. The label extends out from
the bottom left for reference.
Note:
• Be sure to identify the correct expansion shelf by its serial number.
• Be sure to identify the correct expander (A or B) as the one that has
failed.
• If the incorrect expander is removed, an unplanned failover occurs.
Procedure
1. Prepare the array for expander replacement.
a) Log in to the array using the CLI.
Type ctrlr --list --array array_name to determine which controller is in Active mode (A or B).
b) If the controller in Active mode is in the same path as the failed expander, perform a manual failover:
Type failover array_name
ctrlr --list --array array_name to verify that the manual failover placed the controller in Standby mode.
2. Remove the failed expander.
a) Label all cables to ensure proper recabling later, then remove the cables from the expander.
b) Disconnect the power cables from the power supplies of the expander.
c) Loosen the left and right thumbscrews to free the release levers from the expander.
