Gary -
The only way I know is to use DISCUTIL from the ISL prompt, then SAVE the
files off to tape. Then you can use VOLUTIL's RECOVER command to restore
file from the tape(s).
I have never tried this; all I know is that it exists. Perhaps others have
used this or another method and will comment.
I have attached the description/instructions on using DISCUTIL's SAVE
command below (got 'em from HP Instant Information CD).
Best of luck!

Use SAVE to retrieve files from disk and copy them to magnetic tape. You
might use SAVE after a system failure, when a directory has been
corrupted, or when a disk becomes inaccessible to the operating system.
If the volume label or the label table extent blocks are corrupt, SAVE
will stop retrieving files from that disk and move onto the next.
Saving one set of files
You can tell DISCUTIL which files you want to copy to tape. The file(s)
must reside on a disk that was mounted manually or during the startup of
DISCUTIL.
To specify which files you want to save with DISCUTIL, do the following:
1.At the discutil> prompt, enter the SAVE command.
2.At the ENTER FILE SET TO BE SAVED prompt, specify the files you want
copied using either MPE or HFS syntax. You can replace any part of the
file set specification with @ to indicate all members of the set.
3.At the prompt TRAVERSE DIRECTORIES UNDER FILESET (Y/N), press RETURN to
not save any hierarchical directories.
4.At the prompt ENTER THE LDEV, press return to tell the system to search
all logical disk devices for the files. To search a single disk, enter its
LDEV number.
5.At the prompt ENTER THE VOLUME SET NAME, press RETURN to search all
disks. To search one set, specify the set.
6.At the prompt ENTER THE MODIFICATION DATE (MM/DD/YYYY), enter a date to
save only those files in the file set that have been modified on or since a
certain date.
7.At the prompt ENTER THE TAPE LDEV, enter the LDEV number of the tape
drive on which you want to store the files.
DISCUTIL searches the label tables of all ldevs specified for the
indicated file(s). Each time a file is found, and when the file is
successfully written to tape, it prints a message. You may also see other
messages indicating that an error has occured while DISCUTIL was saving a
file.
If the end of a tape is reached before the procedure is complete, DISCUTIL
will prompt you to mount a new tape. Once you have done so, SAVE continues
until all specified files are copied. At that point, the ENTER FILE SET
TO BE SAVED: prompt appears again so that you may specify additional files
sets.
Saving multiple file sets
To save multiple sets of files, do the following:
1.Specify the first file set you want saved, answering each of the
questions DISCUTIL asks. Refer to the preceding set of steps for
information.
2.When you see the ENTER FILE SET TO BE SAVED prompt for the second time,
press RETURN to complete the first tape set and rewind the tape.
3.At the discutil> prompt, enter the SAVE command again. (This begins the
save procedure for the next file set.)
The following is a short sample of the interaction between a user and
DISCUTIL during SAVE:
discutil>SAVE

Subject: lost ldev 1 data recovert on other drives?
It should be Monday.... we lost ldev 1 (sysdisc) about 1 hour ago (I haven't
heard a head crash before, know I have).
Is there any way to save off the data that is on the other drives before we
reinstall the system?
Years ago I remember being told to keep data bases off sysdisc so you could
recover the data from the other drives .. great .... now how do you do it?
This is the first time we have had an actual hardware failure on our 5 year
old 947.
And the first time we have had an System failure since 1992.
