Patch Name: PHSS_1263 Patch Description: This patch fixes various problems with HP OmniBack 2.0 The following problems are fixed: 1. -append to non-OmniBack tapes This is a functionality enhancement. It is now possible to append to tapes that have not previously been written by OmniBack. 2. restore bug for files created 00:00 Jan. 1, 1970 east of Greenwich This fix makes it possible to restore files which have "negative" date-time-modified values. It also fixes a problem where such files were not backed up (unless they were specified in the worklist as a top-level tree.) 3. hardlinks to device special files could not be restored This fix makes it possible to see in the log files that hardlinks to device special files were, in fact, backed up, and to restore these files. In OmniBack 2.0, these files were backed up but were not recorded in the log files. Further, they could not be restored with the 2.0 software. 4. dates in /backup_log off by 10 years This fix corrects a problem where the base date for incremental backups in /backup_log was 10 years ahead of the actual date. 5. volume relative -vs- root relative restore tree specifications This fix address the following problem: Assume, for example, that /users/guest is a mounted volume and that the worklist contains the following entry: volume server1_guest ip:server1 /users/guest With OmniBack 2.0 software, the following restore tree specification (which requests that the entire volume be restored) would not work: -volume server1_guest /users/guest The above restore specification now works. Note: the work around for the 2.0 software was to use the following specification: -volume server1_guest / 6. listing of named pipes in the detail logs This bug is partially fixed. In OmniBack 2.0 named pipes are not listed in the detail logs. With this patch pipes are listed but they are listed as "files". 7. The -exclude option does not behave as it is documented This fix ensures that the correct semantics for the -exclude option are enforced. OmniBack 2.0 has the following erroneous behavior for the -exclude option: If the worklist contains something of the form, VOLUME server1 ip:server1 { -tree / -exclude /foo } then /foo is excluded as is /tmp/foo and /users/smith/foo, i.e. any file or directory whose name is "foo" is excluded. The semantics of -exclude are that ONLY /foo should have been excluded. This is now fixed. 8. During restores using positioning not all hard links may be restored If all of the hard links are within the same directory and there are n hard links, only n-1 may be restored if the restore starts at a position behind the start of the backup volume. 9. After restore, some files may have zero length When a restore is done, some files may be restored without any associate data. They will be restored with their original attributes, but will have a length of zero. This is because the data was not written to the media during the backup. This problem occurs randomly; it cannot be predicted which files will suffer the problem. Further, it cannot be determined from the backup tape or logs which files have been truncated.

Note: Please back up your system before you patch. --------------------------------------------------------------------------- After getting the patch onto your machine, unshar the patch (sh PHSS_1263). To install this patch do the following: 1) Run the update program (Note: you must be logged in as root to update a system). 2) Once in the update "Main Menu" move the highlighted line to "Change Source or Destination ->" and press "Return" or "Select Item". 3) Make sure the highlighted item in the "Change Source or Destination" window is "From Tape Device to Local System ...", then press "Return" or "Select Item". 4) You should now be in the "From Tape Device to Local System" window. Change the "Source: /dev/rmt/0m" to "Source: /tmp/PHSS_1263.updt" (this assumes that you are in the /tmp directory where PHSS_1263.updt has been placed). Note: You must enter the complete path name. 5) Press "Done". 6) From here on follow the standard directions for update. The customized script that update runs will move the original software to /system/PHSS_1263/orig. HP recommends keeping this software there in order to recover from any potential problems. It is also recommended that you move the PHSS_1263.text file to /system/PHSS_1263 to be retained for future reference. If you wish to put this patch on a magnetic tape and update from the tape drive, dd a copy of the patch to the tape drive. As an example the following will create a copy of the patch that update can read: dd if=PHSS_1263.updt of=/dev/rmt/0m bs=2048
