Summary: My Cluster is hosed

Hi ,
      Thanks all for all the emails.
I still have not found the reason why the whole cluster crashed (which is 
scary). No logs to analyse :(.

John Larnier had sent me a document, which allows backup/restoring of 
Cluster_root/usr/var without using tapes.

I got lot of emails for my advfs problem. As always Dr.Blinn was most insightful 
. Tom Smith and he mentioned that I have lost two disk_domains which are 
depended on dsk15c and dsk17c. Since I had done a fresh install I had all my 
disks renamed . So it took me a a while to figure out my domain structure.
  I had lost two more disk_domains which were depended on dsk15c and dsk17c.
For some reason the disk domains (dsk8c and dsk10c )could not be activated .
So I created another volume (thank god I have some spare capacity) and recovered
stuff from tape.
I will be looking into that next week when I'm back in the lab.
Once again I would like to thank all for there help.

Cheers
