Hi
Are you booting from the tape, or using stm?
When you perform the ioscan command, does the server reboot? If it does, you may have some hardware problem.
Be sure to have no I/O on the disks while uprading, ie, if possible deactivate the volume groups where the disks are, or just umount the file system.
Bye
