AIX

Hi Folks,

I am working on a task - Cloning the OS from fullSystem partition to 3 new LPAR's using alt_disk_install.

I just wanted to clarify my steps here.

1. alt_disk_install -CBO hdisk1 and rename it to alt1
2. alt_disk_install -CBO hdisk2 and rename it to alt2
3. alt_disk_install -CBO hdisk3 and rename it to alt3

the 3 profiles/partitions are already created.

4. boot the first new partition into SMS mode and select hdisk1 as boot disk , exit and and boot into normal mode. And same for rest 2.

Am I missing any steps here? I am not sure on do I have to export and or remove the disks first?
All these partitions are on same power 7.

Please let me know. Thanks

Basically, you have to "remove" the disk if you are going to boot a new partition with it. "Remove" in this case is probably, as padmin on VIOS

Code:

$ rmvdev -vtd vtscsiX
$ mkvdev -vdev hdiskX -vadapterN

and once the new, or while, the new partition is starting up
"rinse and repeat"

In short, not "alt1,2,3" but altdisk - 3x

Hi Michael,

Thanks for your response.

Actually we don't have any VIO's on this p7.

So shall I go with below :

rmdev -dl hdisk<>

Well, if you are not using any virtual i/o (could have also been vfcmap for NPIV) then the storage people will have to redefine where the LUN is going.

rmdev -dl hdiskX is only to remove it from the ODM - it does not move the disk.

Well,

The thing is we have 1 fullsystem partition where we have all disks are visible according to sysplan.


So once we deactivate this fullsystem partition, then the new partitions will have these disks visible right?

So I guess here we don't need the movements of disks..

correct me if I am wrong.

Thanks for quick response.
