MSA 1500 MSA20
We currently have an MSA1500 controller with a 12 bay SATA drive array (MSA20). We have a 40 gig logical drive on the array that we wish to remove, without disturbing the other drives, however it was not the last drive to be created.
Is this possible?
We have not yet upgraded the firmware on these devices to the latest, as we are still planning a time to do so. Does the most recent firmware make any changes that would allow us to remove this drive?
Thanks

I believe the restriction still stands, only the last LUN can be deleted.

Re: MSA 1500 MSA20
This rule only applies with drives in the same arraygroup.

Re: MSA 1500 MSA20
This issue with deleting out of order LUNs under an Array, isn't entirely the MSA fault. All Smart Array Controllers have this limitation.
The issue lies with ACU. Think of the ramifications if you allow this to happen. Example three LUNs under Array A, delete LUN1. Now we would have to shift that space toward the bottom. Not a big deal but if you have a fault with a drive during this shifting, then you could potentially loose your data.
