I did a full backup of the system after my reinstall, before doing the Restore from my tape. I had to clean the heads of my tape drive, luckily I still had a cleaning tape and it worked. I restored everything except /etc/conf and the job completed "with exceptions" - but I don't know what they were or if important.
The one problem is that /u is a File System, I know this for a fact, but I don't remember what type of File System. After the restore and reboot, it looks like it tried and failed to mount the /u filesystem - it just said "failed to mount". I know this is where most of the inner workings of my legacy application live, so can you tell me what steps to take in order to try and remount this /u file system?
Thanks - you have been VERY helpful and I appreciate it.

Been reading up a little, it looks like I need to run divvy to create the u division on the disk. Old system had root from 539648 - 10000025, and u from 10000026 - 38973679 (40 GB hard drive)
Current system shows root from 539648 -134070446 (140 GB hard drive) I think divvy will let me create the u division and I can probably figure a size. If this is the correct action, should I first delete everything I "restored" to the /u directory? Then would I create and mount the file system, and do a new restore of the /u on the backup tape?
Let me know if I am on the right track, or what else to do. Thanks again.

amtape
AMTAPE(8) System Manager's Manual AMTAPE(8)
NAME
amtape - user interface to Amanda tape changer controls
SYNOPSIS
amtape config command [ command options ]
DESCRIPTION
Amtape performs tape changer control operations. It uses the underlying tape changer script defined by the tpchanger option for a particu-
lar Amanda configuration as specified by the config argument.
Tape changers maintain a notion of the current and next slot for each configuration. These may or may not correspond to an actual physical
state of the device, but do tend to minimize searching through the tape storage slots. If the desired tape is in the current slot, it is
likely the next tape needed is in the next slot rather than at some random position in the storage slots.
See the amanda(8) man page for more details about Amanda.
COMMANDS
reset Reset the tape changer to a known state. The current slot is set to the first slot. Other device-specific side effects may occur.
Some gravity stackers need to be reset to the top position by hand. This command notifies Amanda the stacker is back in that posi-
tion.
eject If a tape is loaded in the drive, it is ejected and returned to the slot from which it was loaded.
clean If a cleaning tape is defined for the changer, it is used to clean the drive.
show Show the contents of all slots. This can be slow.
label label
Search for and load the Amanda tape with label label.
taper Perform the taper scan algorithm. Load the next tape in the configuration's tape sequence, or a fresh tape with a suitable label.
device Display the name of the current tape device on stdout.
current
Display the current slot.
update Update the changer label database, if it has one, to match the tapes now available.
slot slot
Eject any tape in the drive and put it away, then load the tape from slot slot and reset current.
slot current
Eject any tape in the drive and put it away, then load the tape from the current slot.
slot prev
Eject any tape in the drive and put it away, then load the tape from the previous slot and reset current.
slot next
Eject any tape in the drive and put it away, then load the tape from the next slot and reset current.
slot first
Eject any tape in the drive and put it away, then load the tape from the first slot and reset current.
slot last
Eject any tape in the drive and put it away, then load the tape from the last slot and reset current.
slot advance
Eject any tape in the drive and put it away. Advance current to the next tape, but do not load it.
This is useful with non-gravity stackers to unload the last tape used and set up Amanda for the next run. If you just use eject,
the current tape will be mounted again in the next run, where it will be rejected as being still in use, ejected and the next tape
requested. Using slot next followed by eject does an unnecessary mount.
Note: most changers optimize the slot commands to not eject the loaded tape if it is the one being requested.
