Tim,

It has been a long time since I have restored a unix box, but I can
think of a couple of things about the root. =


The /etc/vfstab file is very critical to booting the box. This is the
file that mounts different partitions. i.e. if you have a 70GB raid
drive and want to use the extra data partition you have to edit
/etc/vfstab and add a mount point for it. I have seen this file get
corrupted and the only time you know it is if you reboot the box. You
could do an interactive restore of this file to a different location and
compare the file. =


HOST file is /etc/hosts which is linked to /etc/inet/hosts.

There can be any number of important files in the root, I would not
trust the drive without restoring root.

Regards,

Ed

Subject: [foxboro] Restoring AW51B to larger drive

All,
Status update on this problem:  I have successfully restored the LARGER
drive with backup tape from the original system.  However, to get it to
restore and reboot without  the "cannot mount root" error I had to
restore everything EXCEPT the root directory.  I did this by REM'ing out
all lines in the QF #991274D restore script that had to do with root
directory file system creation and restore.

 =


Any ideas from this point?  What consequences will I have by not
restoring root from the old system?  I know that the HOST file is
located in the root somewhere.  Is there anything else that is critical?
Any ideas as to what is being restored when I do restore the root
directory that is causing my problems?

 =


Thanks for all of your help on this!

Best Regards,
