Description:
The update installer on AIX hangs at this point (which it reached within seconds, then I waited several minutes):

In unattended mode it is not visible where the installer hangs, but here also it does not end.

May be the fact, that although specifying the "--backupdir" parameter as shown below the installer shows the default dir (relative to the given --installdir) as backupdir cn caus the problem? The given parameter is ignored:

The permissions for the install dir are 'rwxrwxrwx', so I don't think this can be the reason.

How to repeat:
see commands above

no work around available, as using 'n' in the backup question does not help, one is asked for a backupdir and then it hangs as noted above:

----------------------------------------------------------------------------
Current installation backup

Do you want to create a backup during the update process?

Backup the current installation [Y/n]: n

Backup directory [/users/csegieth/merlin/agent/1.2.0.7879/aix5.2-powerpc-32bit/aix52/patchbackup]: /tmp/pino

----------------------------------------------------------------------------

There are three issues reported on this case:

 - Agent update installer doesn't honor the --backupdir folder when --installdir is specified. We sent a fix for this to Keith on December 6th. (case #33018), we tested it thoroughly, maybe is it possible that the mentioned fix was not applied on this case?

 - The installer shows the backup directory parameter even though "Backup the current installation" was set to "no": both parameters belong to the same installer page, but in text mode we show every parameter on a sequential basis, no matter if they belong to the same or to a different page. The problem is that we only evaluate the user input after the whole logical "page" passes (changing this logic would introduce a major refactoring inside the installer code), so the only solution to hide / show the backup directory parameter based on the previous question would be to separate both parameters so they are placed on different installation pages (which is maybe not a desired solution).

 - The main issue, is that the installer hangs during the update process. After reviewing the messages, it seems that the hang occurrs during a copy file process. As we know that there has been another issue related to NFS shares, would it be possible if you try to reproduce the case so that the installer is run outside any nfs folder? (of course, the destination installation directory and backup directory should be placed outside any NFS folder as well).

No feedback was provided for this bug for over a month, so it is
being suspended automatically. If you are able to provide the
information that was originally requested, please do so and change
the status of the bug back to "Open".

The original error for this case was a file copying error operation, that was caused by an NFS problem, and we concluded that it was not really associated to the installers themselves. As we see that the case has been set back again to "Verified", could you please give us more details on what is the problem that was found this time?
