Checking the Status of a LUN

Procedure

  1. On the CLI, run the show lun general command to check whether Health Status and Running Status of the LUN are Fault and Offline, respectively.

    NOTE:
    As shown in the preceding figure, the Health Status values of LUN 0, LUN 1, LUN 2, LUN 3 and LUN 4 are Fault, and the Running Statusvalues are Offline.
    • If yes, go to 5.
    • If no, go to 2.

  2. On the CLI, run the show lun general command to check whether Health Status is Fault, and Running Status is Onlineor Running Fail (the LUN destruction task fails).

    NOTE:
    As shown in the preceding figure, the Health Status values of LUN 0, LUN 1, LUN 2, and LUN 3 are Fault, the Running Status values are Online, Health Status of LUN 4 is Fault, and Running Status of LUN 4 is Running Fail.
    • If yes, go to 3.
    • If no, no problem exists on the current system.

  3. On the CLI, run the show alarm command to check whether an alarm is displayed indicating that a disk in the disk domain where the LUN resides is removed.

    NOTE:
    As shown in the preceding figure, the disk in slot 11 of Enclosure CTE0 in disk domain 0 is removed.
    • If yes, go to 4.
    • If no, go to 5.

  4. Reinsert all the disks whose Running Status values are Offline. On the CLI, run the show lun general command to check whether Health Status of the LUN is Normal, and Running Status is Online or Running Success (the LUN destruction task succeeds).
