Failed to apply sysback on install


  AIX 3.2.5
  RISC 580

  Customer tries to install sysback from diskette
  and it fails to apply sysback and does a clean up
  There are no other messages at all

Action Taken:
restore -Tvq
   Thsi worked fine, so it appears the diskette is 
   readable.  So it appears to be failing somewhere
   in the instal script that is used by installp command
   in sysbacks installp image.
   Below is a method for debugging the instal script

1.  cd /tmp
2.  restore -xvqf /dev/fd0.18
3.  cd /tmp/usr/lpp/sysback
4.  ar x liblpp.a instal 
5.  vi instal
    Add a set -x to each of these functions

    abort() {
        trap 1 2 3 15
        set -x   \#ADD THIS LINE

make_dirs ()   \# Create directory and parent directories
{        set -x   \#ADD THIS LINE

trap 'abort 9' 1 2 3 15
set -x   \#ADD THIS LINE

Save the file

6.  ar -ru liblpp.a instal
7.  /tmp
8.  find ./lpp_name ./usr -print | backup -ivqf sysback.test
9.  installp -acqd sysback.test all 2>&1 | tee /tmp/error.out

This should show where the command is failing at in the
instal script.

It turns out that the customers /usr/ccs/bin/ar command
was of a size 0.  Once we copied that file from another
3.2.5 system the installp worked fine.

Action Plan:
  Closing with customer approval
