Checking the Status of a Disk Domain

Procedure

1. On the CLI, run show disk_domain general disk_domain_id=0 and check whether Running Status of the disk domain is Offline.

   

   NOTE:

   For example, in the preceding figure, Health Status of disk domain 0 is Fault, and Running Status is Offline.
   • If yes, go to step 6.
   • If no, go to step 2.

2. Check whether an alarm is displayed indicating that a disk is removed from the disk domain (ID: 0x100F00A0010).

   For details about how to view an alarm on the DeviceManager, see Checking System Alarms.

   • If yes, reinsert the removed disk and go to step 3.
   • If no, go to step 4.

3. Perform the check again to observe whether the check item fails.
   • If yes, go to step 4.
   • If no, no further action is required.

4. Check whether Health Status of the disk domain is Fault.
   • If yes, go to step 6.
   • If no, go to step 5.

5. Check whether an alarm is displayed indicating that a disk in the disk domain where the storage pool resides is abnormal (fault alarm ID: 0xF00A0001, imminent-fault alarm ID: 0xF00A0003, slow-disk alarm ID: 0xF00A000D or 0xF000A005F).
   • If yes, replace the faulty disk.
   • If no, go to step 6.
