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.

Note:
• If one controller fails, the other controller takes over. The array can function with one healthy controller while the
replacement is installed.
• Replace the array controller if any of its components, such as the NVDIMM, have failed.
• Replacement controllers are shipped without the PCIe cage installed. Before installing the replacement controller,
you must remove the PCIe cage from the failed controller and install it into the replacement controller.
