Retrieval of Load Balance Policy after reboot hp-ux server

[hermesplus]

After reboot we got this message in rc.log:

Start Auto Path recover daemon
Output from "/sbin/rc3.d/S999autopathinit start":

If #autopath retrieve is done, no message is displayed and no change is done in Load Balance Policy.
With command #autopath set... the Load Balance Policy is set.

Q:
How to store the Load Balance Policy to retain it after reboot and in which file it is stored so we can check it?

The persistence settings are kept in /opt/HPswsp/perset. You can run command 'autopath retrieve' to reset the load balance policy based on this file. If for some reason the file is missing, you will have to reset all the load balance manually.

Hi Edi,

Was there any LUN removal happend in this server ?.Please try the below command to find out wherther any LUNs are excluded in autopath.

#autopath display -u

If any devices are listed here which is still connected to server and usable, then you will have to add it back by executing,

#autopath add -l

"autopath retrieve" may fail if the /opt/HPswsp/perset file is corrupted.In that case you may delete/move this file and set the policy once again to recreate this file.

Regards !

Hello,
thanks for your answers...

I am wondering how to check that the file /opt/HPswsp/perset is up to date?

If we do:

/root:#strings /opt/HPswsp/perset

600508B4000111A70000E00000660000
600508B4000111A70000E00000690000

From the above output there is no info about the Load Balancing policy.

We will try to do some tests (if available for reboot) on one test server.

Regards
Edi
