Problem with XSWHWCR1100 - B.11.00.53.8 - Hardware Enablement & Critical patches June 2001

[roobala]

Hi All,

We have HP 9000 L-1000 Server Running with HPUX 11.00, used as a Mail Server.
Initially system came with Sendmail 8.8.6 and later for some new requirements we had compiled Sendmail 8.11.0 which was also working fine.

Recently we had installed the follwing patch.

XSWHWCR1100 B.11.00.53.8 HP-UX Hardware Enablement and Critical Patches, June 2001

Once after the installation Sendmail started giving problem, like for some of the domains it won't relay mails. for the same domains the server which has not upgraded with the patch could send mails.

The error when we send mail is like this.


Mail1 # sendmail -v midas@bom3.vsnl.net.in
midas@bom3.vsnl.net.in... bom3.vsnl.net.in: Name server timeout
midas@bom3.vsnl.net.in... Transient parse error -- message queued for future del
ivery
midas@bom3.vsnl.net.in... queued

When we ask for nslookup for the same domain it could resolve but the same could not be resolved by sendmail,which was ok before patching.

sendmail.org says "some broken resolver library" and asked to recompile the sendmail,which also been tried and could not help.

We tried uninstalling the patch and found the same problem persists.After uninstalling the patch Once again compiled the sendmail after that also problem is there.

This has been cross-verified again by fresly installing the O/S and sendmail + patch and well confirmed it is just after this Patch Only.

Anyone installed this patch and faced similar problem?
Is there any known bugs like broken libraries?
Any updated patch anything came for this?

Thanks in Advance,
Roobala

You said in your message that you have proved that his HWCR bundle causes your problem (by installing it on a test system) but that youve 'TRIED' to uninstall if from your live system but you still have the problem. It sounds to me you havent yet successfully swremoved this bundle. Often it can take quite a bit of work to fully remove an installed bundle. Have you checked for errors ? done an swlist -l fileset on the bundle and compared it to your current system to be 100% sure ALL the filesets have been removed ? normally when you fully remove a bundle everything rolls back perfectly, dont it many times, you just need to be sure its 100% completely removed.

It sounds to me like you have a patch within the bundle that is possibly bad. I would suggest using the custom patch manager on the itrc for you patch updates. You can create customized bundles for your servers that are as conservative as you like, or not. Hope this helps. In the meantime, you need to go through the long process of removing the bundle you had installed, which could take some time. Good luck

Hi Stefan,

But without any error it uninstalled the patch Bundle, and in swlist it is not shown now.
I don't have swlist -l fileset output of system before the patch installation, for me to compare now.

What you have tried to install is a patch bundle, which contains a large amount of individual patches for installation. Like Stefan had indicated, there may be a few patches that were not swremoved. Have you looked at /var/adm/sw/swagent.log for any clues? How many patches total were installed? Hope this helps.

[Stefan Farrelly]

What about checking the /var/adm/sw/swagent.log and swremove.log

The swagent.log will show when the bundle was installed and how many filesets it installed, and when you removed it there should be confirmation the same number of filesets were removed. I suspect these wont match. Can you check ?

[roobala]

Yes Stefan,
U R right,
While installing it installed 105 filesets and while removing it did only 63.

How do I remove now fully?

Roobala

[Stefan Farrelly]

If you do an swlist -l bundle the XSWHWCR bundle doesnt appear ? If so thats the easiest way, just to repeatedly try to swremove it. If not, from the sw logs compile a list of all the 105 filesets that were installed originally and edit it so say swremove for each one, then run it. If you have the source where you got the HWCR bundle from you can do an swlist -l fileset on it and create the list to swremove that way.

eg.
swremove PHxx_xxxx
swremove .....

Youll probably have to add the -x autoreboot=true option to swremove as some will require reboots.

Hi Stefan,

I had unistalled the XSWHWCR1100 from the system, while selecting all the patches bundled in that , which asked to unmark 5 patches or to mark some other 15 o/s patches.

For a safer side I unmarked those 5 patches and uninstalled the rest, Swremove went well without single error, and system rebooted and became a unbootable system.

System could not proceed from ISL> , vmunix.prev or my old vmunix.old backup also didn't work, then I used recovery CD and did the rebuild of Bootlif, and after that system came up with hpux -lm mode, and found everthing fine.

booted from the new kernel (patch removed kernel)which booted without any problem. my sendmail problem also got solved,
which shows,

1. swremove of this bundle causes to corrupt the bootlif. Once after fixing using recovery utilities it is ok.

what could be the probelm? I have similar systems of 12 numbers which is having the sendmail prb, with XSWHWCR1100 installed .
How do I go-ahead on this?

any suggestion pls.

Thanks and Regards

Hi,

For the same case a new observation is as follows,

In XSWHWCR1100 June 2001 Patch Bundle I found the culprit patch , I mean the patch which created the problem (Sendmail), i.e

PHCO_22314 Libc Cumulative Patch,
Once I uninstall this patch my problem get solved, Instead I tried installaing the superseded patches of the same
PHCO_24148 and PHCO_24732, and found the same problem persists.

Is there any known bug like this? any one installed this patch?
Uninstalling this patch will create any problem?

any suggestions pls.

Regards

[roobala]

sorry,

Pls read PHCO_24732 as PHCO_24723
