RAID 1+0 problem
I added two 146 GB HDD in RAID 1+0
Before expend array:
Two logical drive 1- 72 GB, 2 - 72 GB
After expend array:
Three logical drive 1-72 GB, 2 - 72 GB, and 3 - 72 GB,
I don’t understand way the two HDD (146 GB) is not creating a logical drive 3 - 146GB.\
I have a warning message the HDD is not the same capacity.

Re: RAID 1+0 problem
Where did you get this warning and for which drives? This warning means that the two drives are not the same size, maybe you put in one 146Gb and one 72GB drives?
Were you able to see the TWO NEW drives showing up as 146GB drives in ACU?

The above does not mean that Drive 1 is on the two disks ID 2 and ID3 and Drive 2 is on disks ID 4 and ID 5. What it means is that Drive 1 is on all 4 disks and Drive 2 is on all 4 disks.
When you added the new 146GB disks it can not use them.
What you should have done is create a new array B using the two new disks only.

Re: RAID 1+0 problem
I cannot assign a group of physical drives to the same array unless they are of the same capacity. If the drives have different capacities, the excess capacity of the larger drives cannot be used by the array and is wasted.
I must to create a new array B.

The Novell ACU may be different too.

Re: RAID 1+0 problem
I delete the logical drive 3 and now the 2 physical drives is like unused drive but is assigned on A array.
I want to know whatâ s happened if I take off this last drives added in my array A and I restart the server. I can have a message warning about the 2 physical drive is missing?
It is possible to have an option on reboot to delete this drive on my array A?
