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 management GUI Add Enclosure wizard. Select Monitoring > System. From the Actions menu, select Add Enclosures.

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, and all the serial-attached SCSI (SAS) port 1 LEDs must be on. For details about the LED status, see the troubleshooting procedure about understanding system status using the LEDs.
  • Verify that the SAS cabling to the expansion enclosure is correctly installed. To review the requirements, see the troubleshooting problem description about SAS cabling that is not valid.
