Un i x should come up in single-user mode. If the user file system
was not damaged, go to step 14.
If the /usr file system suffered major damage, perform the remaining
steps in this section to restore it.
If you made a separate backup tape for /usr, remove the bootable
backup tape and put the /usr tape in the tape drive.
11. Make a clean user file system:
IRIS 3020:
mkfs /dev/rmd0c
labelit /dev/rmd0c usr sgi
IRIS 3030:
mkfs /dev/rsi0f
labelit /dev/rsi0f usr sgi
12. Mount the new /usr file system and change to that directory:
IRIS 3020:
mount /dev/md0c /usr
cd /usr
IRIS 3030:
mount /dev/si0f /usr
cd /usr
13. Rewind the tape, position the tape to the third file on it, and copy
/usr from the tape to the disk:
mt rewind
mt fsf 2
cpio -ivhmud2
14. Any periodic backup tapes more recent than the bootable backup
tape should now be used to recover the root and, if necessary, user
file systems as fully as possible.
