Severity

INFORMATIONAL

Description

This message occurs when one of the drive in bay 1 or 2 is missing.

Corrective Action

(None).

Syslog Message

Disk shelf %s is recommended to have slot 1 and slot 2 populated at all times.

ses.shelf.changedId

Severity

ERROR

Description

This message occurs on a SAS disk shelf when the disk shelf ID changed after power is applied to the disk shelf.

Corrective Action

Verify that the disk shelf ID displayed in this message is the same as the disk shelf ID shown on the disk shelf. If they are different and the disk shelf ID displayed in this message is the one you want, reset the disk shelf number to match it. If you want the new disk shelf ID instead of the disk shelf ID displayed in the message, verify that the disk shelf ID you want does not conflict with other disk shelves in the domain. Then power-cycle the disk shelf chassis. You can wait to perform this procedure until your next maintenance window. If the warning persists on both disk shelf modules after you completed the procedure, replace the disk shelf chassis. If it persists on only one disk shelf module, replace the disk shelf module.

Corrective Action

Consult system documentation for the maximum number of supported disk shelves, which might be lower than the number reported here. Reduce the number of attached disk shelves to no more than the documented number. Consolidating disk drives into sparsely populated shelves and removing excess shelves is one way to reduce shelf count.
