There seems to be no resource for NetBackup itself.
Resouce dependencies work like this (I will try my best to sketch a text version of a service group here):
NetBackup
(NBU services)
/ \
/ \
Lanman Mount
(virtual name) (Drive letter)
/ \
IP DiskGroup
/
NIC
Resources are onlined from the bottom up.
After Lanman and Mount resources have onlined successfully, the NetBackup resource must be onlined.
The NetBackup resource seems to be missing from the cluster config.
I see these resources going offline and online (you can map them to my picture above):
NIC is a persistent resource (always online) - no need to online or offline.
NetBackup_Server-IP
NetBackup_Server-Lanman
NetBackup_Server-MountV-H
NetBackup_Server-VMDg-H
You can see that there is no NetBackup resource. Something like NetBackup_server-NBU .
This command output will confirm configured resources:
hastatus -sum
Who performed the NetBackup Clustered installation and configuration?
Was it not checked and tested before handing over to the customer?
I found this TN that could explain the absence of a NetBackup resource:
https://www.veritas.com/support/en_US/article.000014833
(The TN is quite old, but worth checking with with Veritas Support to see if TN is still relevant.)
In all honesty, if this is the case, then someone has not done his/her job during initial testing.
