You are at a customer site and assisting with testing a sudden site disaster scenario with their MetroCluster solution. All the equipment at the production site is suddenly powered off, and the command metrocluster switchover -forced-on-disaster true is issued. After the switchover to the disaster site is complete, the customer notices that one of their database applications is offline. All other data is accessible from the disaster site. You notice the following in the volume show output:

Correct Answer:
C
The in-nvfailed-state: true indicates that the volume is in Nonvolatile RAM (NVRAM) failed state, which happens when write operations could not be committed properly during a disaster event. This causes the volume to go into a read-only protected mode to avoid data corruption.
To restore access, you must manually override this state with:
volume modify -vserver SVM1-mc -volume APP02_DB -in-nvfailed-state false
This will bring the volume out of failed state and allow the database application to function again during the switchover.
