AIX

I only see only one disk here, no RAID 10... Im missing something...

Because if this is the case what I submitted in the first place is valid... start by adding ONE new disk to rootvg, and get it to be accepted (because sure you will have to mody PP size for the group) then just do a mirrovg...once done split the mirror and remove the other 72GB disk - not physically: Properly using appropraite commands so you can add your second 144GB disk to the VG and mirror again...

Thanks. I'll give this a try today.

I appologize for forgetting to mention this is a RAID setup.

So, if you have a disk failure, what do you see and where? You surely have something to alert you and manage the replacement.

When you replace a disk, do you get a notification when RAID is back at the required redundancy?

With 2 disks in a RAID set, I'd suggest that is RAID 1 (full disk mirror)

The disks are in RAID 1, AIX's RAID manager calls it RAID 10 for whatever reason. When a drive fails we notifications from diagela and/or the HMC.

Ok, before we beat around the bushes, can you answer the below

1. Are the disk internal SAS or they are SAN disks?
lsdev -Ccdisk

2. If they are internal SAS disks, who created the RAID? you as Admin using diag?

3. If they are SAN disk, they responsibility is of a SAN admin and NOT yours.

Provide the output of the below

Code:

lspv
bootinfo -s <rootvg hdisk>
bootinfo -s <new empty hdisk>
