1 Checking the Status of a Namespace
- On the CLI, run the show namespace general command to check whether Health Status and Running Status of the namespace are Fault and Offline, respectively.

NOTE: As shown in the preceding figure, the Health Status values of namespace 0, namespace 1, namespace 2, namespace 3 and namespace 4 are Fault, and the Running Status values are Offline.
- If yes, go to 5.
- If not, go to 2.
- On the CLI, run the show namespace general command to check whether Health Status is Fault, and Running Status is Online or Running Fail (the namespace destruction task fails).

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

Repair Suggestion : Step1 Reinsert the removed disk. If the alarm persists=> [Step2]. Step2 Collect related information and contact technical support engineers. 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 not, go to 5.
- Reinsert all the disks whose Running Status values are Offline. On the CLI, run the show namespace general command to check whether Health Status of the namespace is Normal, and Running Status is Online or Running Success (the namespace destruction task succeeds).
