Dear Managers ,
Sorry for the late summary ,
But its is most of the times Better late than never ;) .
I got few but good responses and I would like to thank
Roberts ,Izzat and Shawn for putting me on the right track .
Now for the summary
Well for some reason I had a mucked up sysconfigtab, which I had to
restore from backup .
Unfortunately I had erased my hw db so had to rename my devices back
to the old config , that took me a while, but the beast cameback online :) .
I was wondering if there is such a thing for a cluster system .
Shawn had send me a document outlining what has to be done .
Follow these steps after restoring the root disk before booting
GENVMUNIX. For TRU64 UNIX 5.1
