HP Smart Array; Is it possible to convert Raid1 to Raid0 by dropping a failed drive

failedhp-smart-arrayraid0raid1

I have a server that was running two 60GB drives as a logical RAID1. At some point the second drive was physically removed and the logical drive has been in "Interim Recovery Mode" for several months now.

There's no need for the redundancy of RAID1 on this machine, and I have no intention of replacing the missing drive. If possible I would like to convert the current RAID1 to a single-drive RAID0 by simply dropping the failed drive from the current configuration.

I'm only interested in doing this if it can be done in-place. Otherwise I'm perfectly content to leave it in "Interim Recovery Mode" indefinitely.

Yes, it can be done (depending on the controller). You may need the "HP Smart Array Advanced Pack" ($$).

HP calls RAID1->0 "mirror splitting."

Smart Array Advanced Pack is hosted on the Smart Array Controller hardware and can be enabled on the HP Smart Array P212, P410, P410i, and P411 controllers with a Battery Backed Write Cache module or a Flash Backed Write Cache module.. SAAP functionality is standard on the HP Smart Array P812 controller.
