Tech Note Number: 9309
Date: August 9, 1993
Subject: Palindrome Troubleshooting Tip
Error 20: FATAL TAPE ERROR
Affected Products The Network Archivist, version 2.0 -
2.0g
Palindrome Backup Director, version
2.1
───────────────────────────────────────────────────────────────────────────
Symptom:
Backup aborts with "20 ERROR: FATAL TAPE ERROR <tape label>".
───────────────────────────────────────────────────────────────────────────
Cause:
The combined size of the Control Database files have exceeded the pre-
determined limit of 94K. The reserved segment on tape is not large enough
to hold the Control Database when it exceeds
94K and an error 20 is reported.
The Control Database (AS*.PAC) is located in the installation directory.
Place yourself in that directory and list all files that match the AS*.PAC
pattern.
Example:
F:\TNA> DIR AS*.PAC
Note: When listing the directory using the AS*.PAC filter, the only files
displayed should be ASNX.PAC and ASDB.PAC. Rename any other files that
match the AS*.PAC pattern to something other than .PAC. If a file named
ASFT.PAC exists and you are using version 2.0 or later, you may delete
it. This file was used in earlier versions of TNA and is no longer needed
with versions 2.0 and later.
Add up the combined size of the two AS*.PAC files. If the files
displayed exceed 94K, then proceed to the workarounds listed below. If
the combined file size is well below 94K, then you may need to check the
tape and/or tape drive for possible hardware failure.
───────────────────────────────────────────────────────────────────────────
Workaround:
1. Reduce the number of tapes in the library by forgetting tapes that are
no longer needed.
2. Reduce the number of volumes on the protected volume list. This can be
done by splitting the installation into two separate installations.
3. If you are using TNA 2.0d or higher, there is a Palindrome utility
available that can compress the Control Database files, making them
smaller and able to fit on the reserved segment of tape.
Download the utility called PACKCDB.ZIP, password = prime. Follow the
directions contained in the readme file.
Palindrome's BBS number is 708-505-3336 and uses 8N1.
