/etc/name_to_sysnum corrupted

Hi all ,
i have an issue in netra 20 server
when i boot the system its getting rebooting
and it is giving tha" /etc/name_to_sysnum " file not found
i done
OK> boot -ar
then also not solved
please can any body send the answer ASAP

regards

I would boot the server using the boot CD. Mount the root filesystem, fsck the filesystem and check the /etc/name_to_sysnum. If it is corrupt, "mv" it out and reboot the server with the "boot -ar"

I hope this helps.

still not solved
please help me in this

Do you have a boot CD for this system? If so, can you boot into single user? If you can boot into single user, can you see the contents of /etc?
