Hello Syed
Looks like you have corrupted root file system.
Try to boot from instalation CD, and do fixfdmn and (or) salvage.
If you do not know how to do it, say what instructions you need.
I also hope that you have recent backup.

Hello thanks for the response , sorry to say that i am not having any backup for this server since after upgrade from 5.1A to 5.1B I haven't taken the backup .Oracle Database 10g also residing in this server. I have only the cd for Tru64 5.1B patch

Thanks,

You should boot with your operating system cd-rom. After the boot process finished, select "Shell Window" or exit the installation:

>>> boot dka500

Mount the old root domain:
# mount old_root_domain#root /var/mnt
Run the /sbin/advfs/verify command with the -a option.
Run the /sbin/advfs/fixfdmn command.
Recover files with the salvage command and save them to a temporary fileset or tape. If you have an old backup, run the salvage command
with the -d option.

For detailed instructions, see "Recovering from Data Corruption of an AdvFS root Domain" in "AdvFS Administration".

Thanks for the response,
I successfully able to boot
I just done the foll steps.

P00>>>set boot_file genvmunix
P00>>>boot

after restarting the server it take as genvmunix , my question is i have to copy this genvmunix as vmunix or leave as it is.
