Riaan is correct in that you should check the MountV_A.txt log that is located in %vcs_home%\log folder.
If you need asisstance with this process, please open a case with Symantec Technical Support. We are available 24x7x365 to assist with this type of issue.
There is nothing in your opening post that says this FS is a cluster resource?
If this is a cluster resource, please post the Service Group config in main.cf as well as engine_A and MountV_A logs.
If this is not a cluster resource, tell us more about config....
Can you verify that disk/lun is present at OS level at boot time?
Anything in Event Viewer and/or Application logs?
Thank you guys. We did the FC(flash copy) hardware copy using IBM storage and some how it was holding the old info. After rebooted the server I was about to mount the FS.
Thank you for all the helps guys.
