Howto solve this disk error in Solaris in single user mode

UNIX Solaris
1

Hi all,

OS is Solaros 10 Sparc

While doing Netbackup upgradation to 7.5 , the server was asked to reboot.

But then it came up in single user mode,
and after I typed format command it showed some disk error.

bash-3.00# format

Please advise.

Well, your server isn't seeing the required disks. It appears that you have disconnected fiber channel devices and scsi devices. Is it possible your vfstab isn't up to date? Can you post more details on your server and disk configuration that may help?

If this is a hot-swap disk then re-seating the drive might help. Of course, it may be preferable to shutdown the system to do that.

Often just pulling out the drive and putting it back in to remake the contacts is all that's needed.
