Solaris

I have a Sun box that was unplugged for a short while. When I try to bring it up I get an error message "Device not Ready"

I can boot from the Cdrom in single user mode, but not familiar with Unix.

Found another error message bad superblock or wrong magic number. Followed instructions using fsck but didn't resolve the issue.

Any guidance would be greatly appreciated

maybe there is a defect harddrive.... run the "format" command from a shell and post the output. also post the whole message abut the superblock.

appreciate the help but know little about unix and how to format command from a shell

Boot to CDROM (boot cdrom -s)

once in the shell run command:

# format
or
# :| format

//If you see any error, then disk could be bad.

# iostat -En
//look for soft errors and hard errors.

Shutdown the system to OK prompt (commands are halt or shutdown -i0 -g0 -y)
at the OK prompt run these commands without the "OK" :

OK setenv auto-boot? false
OK reset-all
OK probe-scsi-all
//look for errors and also your disk.
OK setenv auto-boot? true
// by now you should have a fair idea as to if the disk is bad or not.
// if the disk is bad, best bet is to get a new disk and reload everything from backup or install new disk and OS, then mount the bad disk and copy any important files you need and trash it.
