This issue has been solved. See solution.
Make sure that the shared disk is not mounted on any node in the cluster.
If applicable, unmount the NetBackup shared mount point. Stop the volume
the mount point is on and deport the disk group for that volume on all nodes
of the cluster.
What exactly happens when active node switch to passive node?I want to know the process

Before break-up, make sure you have a good backup.....  ;-)

Can you please provide my query solution?

i think your query should be at VCS (HA) forum & not NetBackup

If there is node failover, Ideally it resource group which is dependent with Disk resources should also failover to alternate host (May be time consuming , depends upon application)

i wana know the complete process like 

n this case, VCS monitors the NetBackup application on active node at all times and if NetBackup becomes unavailable, VCS will detect this failure, it will gracefully stop everything, unmount the Shared volume from active node, mount on the Passive node and start netbackup there. The failed node can be now worked upon for disaster recovery and backups will be interrupted for just a few minutes.

How this LUN is created and the location?

"i wana know the complete process"

Again - this is a VCS question. Not NetBackup.
See VCS forum in 'Storage and Clustering community'.


"How this LUN is created and the location?"

This is a question for your array support team. Not NetBackup.
The Storage Foundations Forums (
in 'Storage and Clustering community') may also help you.

Storage Foundation and Clustering manuals can be downloaded from:

Very difficult question - what happens is different if I am using VCS on Solaris than if I am using ServiceGuard on HP ...

For example, if I have a clustered application (not necessarily NBU) on an HP metro cluster using an XP array, the filesystem is made readonly on the array on the failing side, and read/write on the failover side, using XP array commands, which is different to what happens if you have a shared disk, which is unmounted from one disk, and mounted on the other.

**NOTE. Above is basic description of details, can't remember the very exact details.

To get the exact details of what VCS does to achive this - please check on the VCS forum, as I will be honest, I have absolutley no idea, as when I do it it works ...  If one day it does not, I will look into why, until then I have too many other things to learn about.

The VCS forum will be your friend ...
