I take it this is a separate pc?

Tar doesn't work quite well when backing up system files, so use cpio instead.

Try the following:

Boot the new system with the rescue disks, set up the partitions.

On the origanal pc insert a blank tape and type:

find "/stand" -depth -print -mount | /bin/cpio -ovcB -O /dev/(tape device)

then copy the / filesystem using a separate tape using the same command as above substituting the / for the /stand.

Once the stand filesystem is copied onto the tape, place in the new PC and type:

mkdir stand <enter>
chmod 777 stand <enter>
mount /dev/boot /stand <enter>
cd stand <enter>
cpio -iudvcmB -I /dev/(tape device)
unmount the /stand filesystem

Place the / filesystem tape into the new pc and type the following:

mount /dev/hd0root /mnt <enter>
cd /mnt <enter>
cpio -icvudA -I /dev/(tape device)
unmount the /mnt filesystem when tape is done

this will put the / filesystem on the hard drive.

Type the following to set up the new hd boot sequence:

/bin/dparam -w <enter>
dd if=/etc/hdboot0 of=/dev/hd0a <enter> (this is the default hd value, if your hd is different then change this parameter)
dd if=/etc/hdboot1 of=/dev/hd0a bs=1k seek=1 <enter> (if you changed the hd value in the above entry, this one must be the same)
/etc/haltsys to reboot

Upon reboot, make a stand directory and chmod 777 it. Add your other mount points and their chmod values.

Then type:

isverify -I <enter>
shutdown -g0 <enter> answer "y" to the question

Once rebooted, you can backup your other filesystems to tape and put them on the new system.

If you have any questions, pls let me know.

tapeinfo

TAPEINFO(1)						      General Commands Manual						       TAPEINFO(1)

NAME

       tapeinfo - report SCSI tape device info

SYNOPSIS

       tapeinfo -f <scsi-generic-device>

DESCRIPTION

       The  tapeinfo  command  reads  various information from SCSI tape drives that is not generally available via most vendors' tape drivers. It
       issues raw commands directly to the tape drive, using either the  operating  system's  SCSI  generic  device  (	e.g.  /dev/sg0	on  Linux,
       /dev/pass0 on FreeBSD) or the raw SCSI I/O ioctl on a tape device on some operating systems.

       One  good  time	to  use 'tapeinfo' is immediately after a tape i/o operation has failed. On tape drives that support HP's 'tapealert' API,
       'tapeinfo' will report a more exact description of what went wrong.

       Do be aware that 'tapeinfo' is not a substitute for your operating system's own 'mt' or similar tape driver control program. It is intended
       to supplement, not replace, programs like 'mt' that access your operating system's tape driver in order to report or set information.

OPTIONS

       The first argument, given following -f , is the SCSI generic device corresponding to your tape drive.  Consult your operating system's doc-
       umentation for more information (for example, under Linux these are generally start at /dev/sg0 under FreeBSD these start at /dev/pass0).

       Under FreeBSD, 'camcontrol devlist' will tell you what SCSI devices you have, along with which 'pass' device controls  them.  Under  Linux,
       "cat /proc/scsi/scsi" will tell you what SCSI devices you have.

BUGS AND LIMITATIONS

       This program has only been tested on Linux with a limited number of tape drives (HP DDS4, Seagate AIT).

AVAILABILITY

       tapeinfo  is  currently being maintained by Eric Lee Green <eric@badtux.org> formerly of Enhanced Software Technologies Inc. The 'mtx' home
       page is http://mtx.sourceforge.net and the actual code is currently available there and via CVS from http://sourceforge.net/projects/mtx/ .
