Error "0511-445 Internal Packing error" When Creating a mksysb tape


OS Level: AIX Version 4.1.x
Type/Model: 990


The following error is received when creating a mksysb tape:
   0511-445 Internal Packing error

One of the known causes of this error is a problem with the backbyname command in which the packing routine has a file size limit. This limit has since been removed.

However, this is not the only reason for the packing error. No files can be opened when the packing routine is accessing them.


The bos.rte.archive fileset corrects this problem in the backbyname command. Also, since the packing routine requires much CPU space, other CPU usage must be kept to a minimum.

Additionally, if you are using a 5GB or 7GB 8mm with compression turned on, it may be better to use the hardware compression without the software compression. To turn off the software compression, complete the following steps:

  1. Change into the /usr/bin directory and open the mksysb file. Enter in sequence:
       cd /usr/bin
       vi mksysb
  2. In the mksysb file, search for pf. This should bring you to a line that reads:
       ${cat} "$archive_lst" | { ${backup} -iqpf"$DEVICE" $BFLAG 2>&1; echo "$?"
  3. Remove the -p flag in the backup portion of the preceding line mentioned. After removal, the only applied flags should be iqf.

  4. Save the file.
This will disable the software packing and eliminate the error.
