How to unconfigure a drive?

Hello

I purchased a new 8x8TB Pegasus32.

I have an old Pegasus3 where one drive has failed.

I would like to use the new 8TB drives from the pegasus32 to replace/rebuild the old pegasus3, one at a time.

(You may wonder why I didn't just buy eight 8TB drives that already come as unconfigured -- it's a long story)

My questions are around how the drives in the pegasus32 may arrive pre-configured (I read they come preconfigured as RAID5) -- but I need them to be unconfigured in order to replace/rebuild in the old PEgasus3. 

Question: What are the steps I should take, and in what order, to unconfigure the drives? I can imagine several options:

- physically plug a new drive into the pegasus3 -- the utility will tell me it can't be used as-is and will allow me to manually unconfigure it for a rebuild

- boot up the entire pegasus32 unit, intact, and during setup, is there some way to unconfigure all drives; and then, once that is done, physically remove a drive from the pegasus32 and insert into the pegasus3 for an automatic rebuild

- other options?

I would really love some feedback before I take action, I'm afraid of ruining something.

Thank you!

Hi Rima,

Please don't send the same question to support@promise.com and then post it to the forum. Do one or the other, I won't be answering every question twice. This question has already been answered in email.

Sorry! I didn't realize these were going to the same people. 

Happy to take the answer from email -- but I didn't see a response to how to unconfigure the pegasus32 drives actually. 

See you on email and sorry again to make double work

Hi Rima,

These questions have already been answered in the support alias emails, but they may be getting stuck in your company spam filter or something. To reiterate the second question about making all the drives unconfigured (already answered in email)...

- boot up the entire pegasus32 unit, intact, and during setup, is there some way to unconfigure all drives; and then, once that is done, physically remove a drive from the pegasus32 and insert into the pegasus3 for an automatic rebuild

If the drives are in the default RAID5 configuration, make sure the Pegasus is fully booted, start the CLI by opening a terminal and entering 'promiseutil', then enter this command.

array -a del -d 0

This will make all array drives inserted unconfigured.

This won't work on passthru or spare drives. Do not use drives in a PFA condition.

EDIT: To use the Promise Util CLI you need to install the Promise Utility for the Pegasus32, not Promise Utility Pro.
