Copying a boot disk of an up and running vPar to another vpar in HPUX Itanium [11i v3]

willsfrazer — Tue, 19 Aug 2008 11:28:08 GMT

Hi,

This might sound strange but is there something like this :

Copying a boot disk of an up and running vPar to another vpar in HPUX Itanium [11i v3].

Whole idea is to see if we can add a raw disk to a vpar, let's say vPar1, which has an OS image and it's configured properly with all n/w, system and file system configuration. Now copy the image in such a format to this newly added raw disk that when we remove this disk from the vPar1 and add as BOOT disk to another vpar, assume vPar2, and say "vparload -p vPar2" it should load[come up with] the same image and configuration which we had on the vPar1. Then we could configure it as we want by logging in to it from MP console using same credentials of vPar1 and change the n/w configuration and other configurations if we want.

Now writing to a raw disk should be handled through adding it as new logical volume on vPar1 as image should be written only in new disk so that could be used for vPar2. Though not sure if we can specify using logical volumes that write to this particular disk only .

Is anything of such sort possible. I do not want ignite capturing as deploying image from ignite will require me to do n/w, system and file configuration at booting time, which I do not want. What I want is let me bring up the server with some default configuration so that I can install Ignite base[client] package on it and then I could use this setup for deploying the image through Ignite without doing any configuration manually.

Hopefully I conveyed what I am trying to do...

Shalom,

While I suppose you can use dd to copy a boot disk to a network destination, the supported way to do this is Ignite.

I never did this so far, because I only used ignite golden images or cold installations.

But I think you can "clone" the disk (think about DRD - dynamic root disk), assign the disk to another vPar, boot this vPar into single user mode and adjust hostname, IP, etc...

In case you "clone" with "dd", boot into single user mode first and use vgexport/import to adjust vg00 to the new H/W path.

Thanks for the help. Cloning works for me withh dd as I could bring another vPar up, but when I boot the vPar with cloned disk it gets lan card of source vPar with it and hence new cloned server has two lan cards, which I do not want as I want one card still to be with source vpar. When I bring the server which hosts both source and cloned vpar to nPar mode all the hardware resources seem to be in place, so VPDB does not have problem, the cloned disk is to be configured to release first vPars lan card, Any suggestions how can I do it.

-Thanks.

You have only this IO in vpar1:

IMHO this includes all beneath 1.0.0, but seams to be a little less.

Your vpar1 has only 1 LBA: 1/0/0.

You have a dual scsi HBA - that's it. No configured lan device at all.

Hi,

It's not that vpar1 did not or does not have any lan configured. Before I cloned the vPar3 with cloned disk, vpar1 was showing this :

Even now if I boot server in nPar mode everything seems to be fine as vpar database has entries right.

It's when I booted vPar3 with cloned boot disk[source boot disk is vpar1's boot disk for cloning] vpar3 automatically took ownership of lan of vpar1 as well. Might be due to system configuration which cloned disk had same as of vpar1. And this is what I want to change after cloning so that resources of vpars remain as they were assigned initially even if I clone boot disk n number of times and boot different vpars with those disks.

Thanks.
Wills.

IMHO you have a general problem wit I/O assignments.

Somehow you did configure the same path to vpar1 and vpar3. (1.0.1)

You should *always* use the LBA in any assignment (except boot disks), for example:

-a io:1.0.1
-a io:1.0.0
-a io:1.0.0.3.0.6.0 BOOT

Your vpar3 has

1.0.1.1.0.1.1.6.0.0.0.0.0 BOOT

and your vpar1 has

1.0.1.1.0.4.0

This is NOT possible!

Hi,

Initially boot disk for vPar3 was 1.0.6.1.0.1.208.0.0.2.2

then i changed it to 1.0.1.1.0.1.1.6.0.0.0.0.0 as this one is cloned disk and I was trying to boot vPar3 with this new boot disk.

So the conclusion is that I am doing a wrong configuration of resources.

How do we see what are all LBA's in nPar. And what is the correct assignment of these IO devices across the vPars depending upon these LBAs

Thanks.
