Cause

When many devices exist, the system recognizes them all when restarted.

However, some VxFS devices that are related to MSDP and AdvancedDisk are only recognized and mounted in the final stage of the restart.

NetBackup depends on the mounting of these related devices.

When NetBackup starts, these devices have not been mounted yet, which causes NetBackup to fail to start.

Solution

Use the following commands in the NetBackup Appliance Shell Menu to restart NetBackup:

Support> Processes> NetBackup Stop

Support> Processes> NetBackup Start
