On one of our systems it appears 2 disks are defect. It is a rx 2620 server with 11.23 HPUX
First disk is the mirror of boot disk and the second one is a non boot disk and one of a group of 4 disks in a volume group. mirrored and pvgroup.
Both disks are not seen anymore in an ioscan.
Where can I find the exact steps to replace the disks and make sure no data is lost?
Thanks, Alfons
Solved! Go to Solution.

Re: replace disk
It seems unlikely that *two* disks have actually failed. Check your cabling and your disk controllers in 'ioscan'.

Re: replace disk
It is a system in another country where the administrator is on vacation.
This morning the machine acted real strange, so I took a look at it.
The non root disk crashed this morning (Oracle Instance running on it)
Looking at the output of ioscan I only did see one root disk. In the syslog I could see that the problem with the root disk started on 17 june.
The disks do have different controlers.
Thanks, Alfons

Re: replace disk
Can you provide following info here. We can help you to make out steps for you then.
#vgdisplay vg00
#vgdisplay -v vg00
#ioscan -fnC disk
#ll -rt /dev/*/group
and vgdisplay -v for another VG.

Re: replace disk
So that you can minimize the risk of running system on single disk.
Do you have ignite backup on tape using make_tape_recovery?

Re: replace disk
>>be some other issue.
Agreed. If you have a support contract you should definitely log a call so HP can analyze and get you the parts, disks or whatever, that you need.
>>Two disks cant be defective at sametime.
That is absolutely NOT true. While the chances are low for 2 to be defective at the same time it is absolutely possible.
If you read one of the responses you will notice that it was said that one shows defective as of June 17. So if the other one failed recently that is essentially a span of 2.5 months between failures, which changes the odds considerably.
