Problem: New expansion enclosure not detected

Determine why a newly installed expansion enclosure was not detected by the system.

When you install a new expansion enclosure, follow the Add Enclosure wizard in the management GUI. Select Monitoring > System and select Add Enclosures. If Add Enclosures is not available on the System -- Overview page, there might be a cabling issue that needs to be verified.

If the expansion enclosure is not detected, complete the following verifications:

Verify the status of the LEDs at the back of the expansion enclosure. At least one power supply unit must be on with no faults shown. At least one canister must be active, with no fault LED on. For details about LED status, see Procedure: Understanding the system status from the LEDs.
Verify that the SAS cabling to the expansion enclosure is correctly installed. To review the requirements, see Problem: SAS cabling not valid.
