quorum string on boot drives

[Rick Garland]

Hi all:

Got HPUX 11.11 on PA and 11.23 on IA.
Have a project to check the quorum strings on the mirrored boot drives. Check the override quorum. (Not really sure what is being asked so I put it out here.)

Anyway, what the goal is to check the mirrored boot drives to ensure that all configurations are correct and in place for failover boot.

Looking for some guidance/opinions on how I would proceed.

From what I have gathered, I would be using the 'lifcp' and 'lifls' commands, but what I am looking for?

Obviously the ultimate test for mirrored boot drives is to bounce the box and switch the drives. This is not doable, I need to be able to run commands and see the output.

Many thanks

Find the boot devices for the machine, then do:

lifcp /dev/dsk/c1t0d0:AUTO -

(Note the between the O in AUTO and the '-')

This copies the boot string in the AUTO file in the lif area to STDOUT. What you should see is:

hpux -lq

If you have mirrored disks, then BOTH disks need to have the '-lq' so that either can boot if the other disk fails.

For IA systems :

efi_cp -d /dev/rdsk/c2t1d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.pri

cat /tmp/AUTO.pri

Note: change c2t1d0 with you actual disk.

this is from knowledge base doc for mirroring root disk for IA.

Thanks Patrick - so al I am looking for is the hpux -lq

Correct?

First,

do a lifls /dev/dsk/c1t2d0 and make sure that an AUTO file exists -- using the desired disk device, of course.

Next, copy the AUTO file to a UNIX file.

lifcp /dev/dsk/c1t2d0:AUTO /var/tmp/auto

cat /var/tmp/auto and see if the "-lq" option is specified.

Normally, I add the -lq option to hpux via mkboot -a on both the primary and alternate boot drives; otherwise the machine becomes less likely to boot unassisted should a drive fail because both mirrors would be required without this option. The downside to setting -lq on both drives is that it is possible to overlook the failure of a drive BUT any sysadmin that allows any failed drive to go unnoticed for any significant period of time should be shown the job egress door.

Hi Rick,

your test on an Integrity disk (see Ivan's post) should return this result:

boot vmunix -lq

for the quorum mode.

You may set this mode with this commands:

# echo "boot vmunix -lq" > /tmp/AUTO.lq
# efi_cp -d /dev/rdsk/c3t2d0s1 /tmp/AUTO.lq /EFI/HPUX/AUTO

(replace c3t2d0 if needed)

Another thing to make sure is that the alternate boot path, autosearch and autoboot are listed and enabled by running setboot on the command line.

Reopening this thread.

I am having trouble with the IA systems.
I have posted my commands and results here. Essentially I am getting the message that my boot devices are not efi partition. I know this particular system boots because it was bounced last night. No, did not test the mirror boot.

Per the posts from above, I should be see the "boot vmunix -lq" message. But instead I am see the "invalid efi partition" message.

Any clues?
Thanks

No hits - open new thread.

The "s2" is HP-UX. "s1" is EFI.

You must use cxtydzs1 (note "s1") in the command.
