ISSUE:

STACKER BOOT TIME ERROR MESSAGES

MESSAGE1:
X: = Y:STACVOL.xxx Cannot find STACVOL file - NOT MOUNTED

EXPLANATION1:
This message suggests that a STACVOL.xxx file has been deleted or the
STACKER.INI is incorrect.

ACTION1:
If the STACVOL.xxx file has been deleted, the STACVOL.xxx file may
remain UNDELETED as long as you have not written additional data on
to the drive that contained the STACVOL.xxx file.  Otherwise,
UNDELETE will not be able to recover the STACVOL.xxx file because a
portion of it has been written over.

The STACKER.INI may be searching for a STACVOL.xxx file on the wrong
drive.  Check the STACKER.INI file to make sure each line that loads
a STACVOL.xxx file points to a drive that actually contains a
STACVOL.xxx file.

EXAMPLE1:
/C:\STACVOL.XXX,SW

MESSAGE2:
X: = Y:STACVOL.xxx Updating Stacker allocation map...OK

EXPLANATION2:
This message suggests that the data on a compressed drive does not
correspond to Stacker's internal table for keeping track of where
that data is located.

ACTION2:
Do nothing.  Stacker will adjust this automatically.

MESSAGE3:
!!! Stacker not found to relocate - nothing done.

EXPLANATION3:
This message indicates that the STACKER.BIN device driver is not
loaded and cannot be put into Upper Memory by the STACHIGH device
driver.

ACTION3:
The STACKER.BIN device driver needs to be in the root directory of
the bootable partition. STACKER.BIN has the (R)ead only, (H)idden,
and (S)ystem attributes attached to it. You can reinstall STACKER.BIN
by SYSing the boot partition using a Stacker aware boot disk (with
SYS on the disk). Or you can build STACKER.BIN by combining
STACLOAD.BIN and STACKER.COM files using the following command:

               COPY /B STACLOAD.BIN + STACKER.COM STACKER.BIN

=====================================================
STACKER RUN TIME ISSUES

MESSAGE4:
No error during bootup. After bootup a DIR on the compressed drive
does not list the files that should reside there.

EXPLANATION4:
This suggests that the STACKER.INI file is bad or missing.

ACTION4:
Check the root directory for a (H)idden STACKER.INI file.  If it does
not exist, create one as such the following:

               /P=1
               /DIR=C:\<Novell DOS 7 directory name>
               /X:\STACVOL.xxx,sw

where <Novell DOS 7 directory name> is the name of the directory that
contains your Novell DOS 7 files.

where /X is the drive that contains a STACVOL.xxx file.  This line
would be included for each of the drives that contain STACVOL.xxx
files.

MESSAGE5:
UNSTACK gives the message "Unable to open STACVOL file x:\STACVOL.DSK
for verification.

ACTION5:
Check to see that the drive that contains the STACVOL file has not
been overwritten by a network drive.  Log out and run UNSTACK again.

=========================================================
STACKER MAINTENANCE ISSUES

Third-Party Surface Scan and Fix:

Run all surface scan and fix programs on the uncompressed portion of
a Stacker drive (drive containing STACVOL.xxx) without the Stacker
drivers loaded.

If an error is found within the STACVOL.xxx file, do the following:

     1.   Exit the surface program.
     2.   Remove the attributes on the STACVOL.xxx file.
     3.   Run the surface scan on the drive again and allow it to fix
any problems.
     4.   Return the attributes to the STACVOL.xxx file (+RSH).
