Mirroring on itanium server

boomer_2 — Thu, 12 Apr 2007 00:18:05 GMT

Hi guys,
I have a setup of 2 HP rx4640 server with hpux 11i v2 on it..itanium processor.
I would like to check whether mirroring is there or not...
From the below info i suppose mirroring is not done.
now how do i come to know the exact disk path of my second internal disk and how do i mirror it as i havent mirrored itanium server boot disk...also can i do it online...?

Hi,

the info

# lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/dsk/c2t0d0s2 (0/1/1/0/4/0.0.0) -- Boot Disk
Boot: lvol1 on: /dev/dsk/c2t0d0s2
Root: lvol3 on: /dev/dsk/c2t0d0s2
Swap: lvol2 on: /dev/dsk/c2t0d0s2
Dump: lvol2 on: /dev/dsk/c2t0d0s2, 0

indicates there is only 1 boot disk.

BUT,

disk 1 0/1/1/0/4/0.0.0 sdisk CLAIMED DEVICE HP LOGICAL VOLUME
/dev/dsk/c2t0d0 /dev/dsk/c2t0d0s3 /dev/rdsk/c2t0d0s2
/dev/dsk/c2t0d0s1 /dev/rdsk/c2t0d0 /dev/rdsk/c2t0d0s3
/dev/dsk/c2t0d0s2 /dev/rdsk/c2t0d0s1

indicates this is a *hardware RAID*!

"HP LOGICAL VOLUME" is telling this.

So the disk looks like hardware mirrored and not LVM mirrored.

A full "ioscan -fn" may be helpful.

Re: Mirroring on itanium server

Shalom,

Software Mirroring is not set up.

You if you have disk can get mirror/ux and do it with software.

You may also be able to get a smart array and do your mirroring with hardware just like with a DL380. The rx6600 and rx3600 series now have a hardware raid card available.

Hi steve,
i do have 2 internal disks...but what abt hardware mirroring what if my boot disk fails now then can i just remove the failed disk and put the other disk which is hardware mirrored in place of it and carry out the syncing.

also
swlist|grep -i mirror
shows nothing....

This is the IMPORTANT part here:

As you can see, you have a smartarray controller installed:

This HARDWARE RAID is serving your boot disk:

Please run

# sautil /dev/ciss2

to get more information about the RAID config.

Re: Mirroring on itanium server

It is all in the output - your 2 internal disks are mirrored via the smartarray controller.
Looks fine!

Hi torsten,
Thnx for the information...
But what if one of my boot disk fails how do i replace it with the other one which is mirrored.
How will i come to know which has failed ?

Re: Mirroring on itanium server

This would be like with any other smartarray in any other system - you will see a red light on the disk. Swap it out and a new drive in and the controller will mirror again.
Additionally the diagnostics will inform you about errors.

hi Torsten,
that means even if my boot disk fails the control would be automatically transferred to other boot disk..right...
and after replacing failed boot disk it would resync on its own ..no command would be needed right..

Thanx for being patient with me...very very thnx...

You are right.
For safety check with "sautil".

Points are welcome - have fun!

I will just add one thing, as the main questions around mirroring were pretty much nicely answered.

Rx are itanium systems, and as such, they have a bit different disk layout for boot disks. Reasons why your pvdisplay commands on c2t0d0s1 and c2t0d0s3 and whole c2t0d0 failed were:
These three guys (drive and 2 partitions) are not part of LVM, so using pvdisplay on them where there are no lvm structures on those disks is useless (and might confuse some people). c2t0d0 is the whole disk from the view of OS. c2t0d0s1 is system partition (500M) with efi stuff. c2t0d0s3 is service partition (400M) with diagnostics. This partitioning is valid only for boot disks on itaniums. All other disks are treated as usual.
