On the CLI, run show storage_pool general pool_id=0 and check whether Running Status of the storage pool is Offline.
NOTE:
For example, in the preceding figure, the Disk Domain ID of storage pool 0 is 0, Health Status is Fault, and Running Status is Offline.
If yes, go to step 6.
If no, go to step 2.
Check whether an alarm is displayed indicating that a disk is removed from the disk domain where the storage pool resides (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.
Perform the check again to observe whether the check item fails.
If yes, go to step 4.
If no, no further action is required.
Check whether Health Status of the storage pool is Fault.
If yes, go to step 6.
If no, go to step 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.
