Resolving a problem with new expansion enclosures

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. SAN Volume Controller 2145-24F and 2145-92F enclosures have two LEDs per Serial-attached SCSI (SAS) port: one green link-status LED and one amber fault LED. The link status LED of the ports that are in use is on while the fault LED is off. For details about LED status, see SAN Volume Controller 2145-24F and 2145-12F expansion canister SAS ports and indicators and SAN Volume Controller 2145-92F expansion enclosure LEDs and indicators.
Verify that the SAS cabling to the expansion enclosure is correctly installed. To review the requirements, see Connecting the optional 2145-92F SAS expansion enclosures, Connecting the optional 2U SAS expansion enclosures to the 2145-SV1, and Connecting the optional 2U SAS expansion enclosures to the 2145-DH8.
