swinstall question

Michael D'Aulerio — Tue, 07 Sep 2004 11:05:10 GMT

I'm a littled confused by the behavior of swcopy and swinstall on my system and was hoping someone out there could explain it. I'm trying to install patch PHKL_23418 (mount(2) cumulative patch) on a B180 running HP-UX 10.20. When I tried to create a SW depot, I got an error from swcopy that it could not create the depot because the patch PHKL_16750 (SIG_IGN/SIGCLD,LVM,JFS,PCI/SCSI cumulative patch) was not in the depot. PHKL_16750 is already installed on my system but I added it to the depot anyway.

I ran swinstall and marked PHKL_23418 for install and PHKL_16750 was marked also because of dependencies. After PHKL_23418 installed, I checked the swinstall.log and swagent.log. The analysis showed that the install for PHKL_16750 was to be skipped because it was already installed on the system.

Don't swinstall and swcopy check what patches/products are installed on a system before marking products to be installed. Are there any flags I need to set or parameters I must pass to swcopy and swinstall to get them to ignore errors for patches that are already installed. This thing's got me stumped. Thanks for any help.

Mike

The analysis phase determines if a patch has been installed already. This occurs after the patches/products are marked.

Hi Mike,

When you swcopy any depot, you would need to put all the dependencies in that depot. You can overwrite it with swcopy options. Swinstall will give out a warning. This was your first problem.

Secondly, the answer is no. It is done during the analysis phase.

swinstall/swcopy don't do any checking until the analysis phase which occurs after the sofware has been marked.

There are are couple of options that you can change:

interactive:
[ ] Enforce dependency analyis errors in agent
[ ] Autoselect dependencies when marking software

command line:
-x enforce_dependencies=false
-x autoselect_dependencies=false

Be very careful when disabling dependency enforcement. SW may not work properly if dependencies have not been resolved when it is installed. However, I typically turn-off the dependency checker when I am copying patches to my patch depot.

swcopy by default will check that dependencies exist in the depot.

You can tell swcopy to ignore dependencies in the case where the dependencies are already installed:
# swcopy -x enforce_dependencies=false ....

The dependencies for PHKL_23418 include
PHCO_18563
PHCO_23844
PHKL_16750
PHKL_16959
PHKL_17857
PHKL_20610
PHKL_21594
PHKL_21660
PHNE_22506

Thank you all.

I'm going to try the -x enforce_dependencies=false option of swcopy.

I think I'll stay away from -x autoselect_dependencies=false for swinstall for now.

I dont see there is any way of skipping the analysis that if the product/patches are already installed on the system.
You can also use swinstall -p -s on the patches you want to install which will tell you clearly the analysis.
You can set the options for installation in /var/adm/sw/defaults file for installation. Before that do not forget to read the patch description at ITRC.
Hope it helps
Thanks and regards
Prashant

Thanks all. I used the -x enforce_dependencies=false option of swcopy and it works fine.
