Problem Description:
The TSM 4.2.2 UNIX backup-archive clients may produce error messages
similar
to the following when performing incremental backup of files with hard
links:
ANS1228E Sending of object '<filename>' failed
ANS4018E Error processing '<filename>': file name too long
where <filename> is the name of the file that failed to back up. It is
important to note that file names experiencing this problem are NOT too
long.
Message ANE4018E (same text as ANS4018E above) may also be logged to
the TSM
server.
This problem affects files that have hard links. For affected files,
the
problem occurs only during incremental backup. SELECTIVE backup of
these
files works correctly.
For files that have hard links, both the link and the original file may
be
affected by this problem: If the original file does not have a backup
version
on the TSM server, then the original file will experience the problem.
If the
hard link does not have a backup version on the TSM server, then the
hard
link will experience the problem.
Files with hard links where the file already has a backup version
(regardless
of whether the link has a backup version) are unaffected.
Hard links where the link already has a backup version (regardless of
whether
the original file has a backup version) are unaffected.
Files that have no hard links are unaffected.
Client APAR IC33645 has been opened to address this problem.
The version 4.2.2 UNIX clients have been removed from the FTP download
site.
They will soon be replaced with newer client code that fixes this
problem.
Circumvention:
Use SELECTIVE backup to back up those files that are affected by this
problem. They can be identified by reviewing the ANS1228E and ANS4018E
messages in the dsmerror.log file.
The backup-archive GUI may also be used to back up these files. From
the
GUI, be sure to select the "Always backup" option (located in the
drop-down
list to the left of the "Help" button).
Alternatively, customers who were running an earlier 4.2.x version of
the
client can remove 4.2.2 and reinstall the earlier version. Customers
who
upgraded from version 4.1.x or below can not back off, and must use the
circumvention described above. We plan on having a fix available soon,
so
this circumvention is viewed as being very short-term.
Users Affected:
All TSM 4.2.2 UNIX backup-archive clients.
Recommendation:
Apply fixing code when available. We anticipate that the fix will be
delivered on or before the end of May 2002.
