Move logical drive 1 from P400 to P800

[Marko H.]

I have a DL380 G5 with SA P400 and SA P800.
The SA P400 has 3 physical disks in RAID5 and logical drive 1 - this is also boot disk.
The SA P800 has MSA50 attached to it with 10 physical disks in RAID5 and logical drive 1 on them.
I need to move the disks from SA P400 to SA P800.

Here is my plan:
Shut down the server.
Disconnect the MSA50 from the P800.
Move disks from P400 to P800.
Boot and save the config in P800.
Shut down the server.
Connect MSA50 back to P800.
Boot the server.

And here is my dilemma:
will the logical drive 1 from SA P400 stay logical drive 1 when attached to SA P800?
As far as I know the OS will always boot from logical drive with lower number.

hi Marko

will the logical drive 1 from SA P400 stay logical drive 1 when attached to SA P800?

- yes it should

As far as I know the OS will always boot from logical drive with lower number.

- you're right

let us know the results

I'll replace it next week and let you know then.
I know logical drive 1 from SA P400 should stay 1 when I move it to SA P800 if I stick to my plan.
But there is this "should".
I am also asking if someone has done this with P and E controllers and has a good experience.

hi marko,

will the logical drive 1 from SA P400 stay logical drive 1 when attached to SA P800?

as you and Karlo said it should function.
But if thats not the case you can try this as a workaround:

Use system recovery and the map arc command to edit the boot.ini to reflect where c:\windows is detected:


And change for example from:

multi(0)disk(0)rdisk(0)partition(1)\windows

To:

multi(0)disk(0)rdisk(1)partition(1)\windows
