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 label is located above Expander A.

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.
