Add drive to existing array after moving servers

[art76]

Hi All,
Here's the situation. Have a DL360 G3 which failed on the weekend and to get our websites up quickly I just moved 1 of the mirrored drives to a spare DL380 G3 I had spare.

Now I only moved one of two drives from the mirrored RAID so I would have one good backup drive.

So, now on the DL380 I need to add a spare drive I have become the mirror of the working drive from the DL360.
Going into ACU I see both drives with the working drive being in Array A but I can't seem to add the second empty drive I have to this array. Anything I do just makes an Array B which isn't very useful to me.

I have broken mirrors before to put bigger hard drives in but it just isn't working for me this time.

Looking for some help. TIA.

I doubt this issue is because the raid is not properly set. However, if 2 arrays are available delete one array and expand the existing array.

Also, check the raid settings in ACU or ORCA by pressing F8 at POST.
