Hello everybody.
I created mirror disk in RX2620 itanium server , followed this procedure:

Hi,

It seems that step are ok, Only one thing is missing that is "setboot -b on". Try this command and then check it again.

Please find the attached script for Mirror disk.

There are wrong steps!

How about the output of your commands?

You did
mkboot ...
commands and later a
pvcreate ...

You did NOT mirror the swap.
You did not

lvlnboot -r /dev/vg00/lvol3
lvlnboot -b /dev/vg00/lvol1
lvlnboot -s /dev/vg00/lvol2
lvlnboot -d /dev/vg00/lvol2

Finally, I don't know what you did, but I think you mirrored
/tmp
to lvol1 (should be /stand).

I would revert the changes and start over.

Here are the links to the manuals - make sure you run the commands in a correct order

I recreate the disk mirror using the correct secuence and now works fine. The server boot from the secondary when i remove the primary, but if i remove the secondary booting from the primary the server generates a crash dump. When i re install the secondary disk the system boots again. What i am doing wrong ?

Thanks in advance

Did you capture the messages?
Is it really the primary having the problem?
Did you mirror the swap this time?

Check "vgdisplay -v vg00" carefully.

Hi!

Is your AUTO file on the primary disk correctly configured (boot vmunix -lq?

I do not capture message.
Yes it is the primary have the problem , because i take off secondary disk.
No, I do not mirror swap area. I send the output commands.

Of course you need to mirror the swap too.
Why you didn't?

The swap must be the second lvol mirrored, so remove the mirrors again and mirror the swap.

BTW,
grep "Boot device" /var/adm/syslog/syslog.log
Oct 2 20:26:58 SAPDESA vmunix: Boot device's HP-UX HW path is: 0/1/1/0.1.0

this is the "secondary" disk (without swap).

Hello Torsten.

Yes, it is secondary disk (Oct 2 20:26:58 SAPDESA vmunix: Boot device's HP-UX HW path is: 0/1/1/0.1.0 .

I have another question.
I create a secondary swap area by requirement of SAP people.
I think mirroring this swap area too.

You really should mirror everthing - especially the swap!

If the disk containing the un-mirrored swap is failing, you can compare this to a failed memory. Imagine what happens to your OS ...
