Arrival or recovery of the volume does not bring the file system back into online state making the file system unusable
A disk may fail or a connection to a disk may fail. In such cases, if storage tolerance is exceeded, the volume that is constituted from that disk becomes disabled. The disabled volume causes the file system to go to an offline or faulted state making it unavailable for usage. After the underlying problem is corrected, the disk recovers and the volume also becomes enabled automatically. However, the file system does not come online on its own. This issue applies to all the file systems in the NetBackup Flex Scale cluster. (IA-25435)
