Mount problems !!!
After some latest patches installation on HP-UX11i server, one of the volume group fails to get activated and the filesystems under this volume group are not mounted.
After activating the volume group using vgchange -a y , problem was solved but with every reboot it occurs again.
Any suggestions to get rid of this problem.
Thanks
Venky

Re: Mount problems !!!
Could you attach the contents of the following, or review for completeness and accuracy:
strings /etc/lvmtab
vgcfgrestore -f /etc/lvmconf/vg##.conf -l
strings /etc/mnttab | grep -i vg##
cat /etc/fstab | grep -i vg##
Finally, please check the LOGTOOL utility in STM.
STM > TOOLS > UTILITY > RUN > LOGTOOL > FILE > VIEW > RAW SUMMARY.
Note the first and last dates of transactions and calculate the difference. If the difference is short, like 4 hours, then this is important to note. Now read down the report of hardware addresses and observe the integer numbers in parenthesis. Anything over 150 in this 4 hour period should be called into HP for replacement.

Re: Mount problems !!!
AUTO_VG_ACTIVATE is set to 1 in /etc/lvmrc file.
Frederick : I have checked the outputs as mentioned in your reply and all the files have relevant entries for the problematic VG.
Thanks

Re: Mount problems !!!
The VG would be activated via the /sbin/bcheckrc which checks /sbin/lvmrc exists and is executable. If the AUTO_VG_ACTIVATE=1 is set then the VG should be activated on bootup.
Check both are readdable ane executable .
If the VG has failed to activate and if /etc/fstab has an entry for the mount of the filesystem then I would expect an ERROR in the /etc/rc.log under:
Mount file systems
Output from "/sbin/rc1.d/S100localmount start":
----------------------------
Its a bit strange you don't see any messages in /etc/rc.log .
Hope the above helps .

Re: Mount problems !!!
As a work-around or just for testing, in lvmrc, set AUTO_VG_ACTIVATE to 0, and activate all your volume groups (especially that, that makes problems) explicitly within the custom_vg_activation subroutine, e.g.
custom_vg_activation()
{
/sbin/vgchange -a y /dev/vg01
/sbin/vgchange -a y /dev/vg02
return 0
}
Maybe, this will produce some valuable error messages, or hints to the problem solution.
