Using two RAID arrays on one controller in turn?

Question

RAID

Good afternoon.

I have an old server with 4 x 2 TB disks in RAID10, vmware
Can I do the following due to the lack of necessary resources.
1. Pull out all 4 disks.
2. Install new 4 disks for the weekend, create a raid, deploy OS, services, etc. tasks
3. Pull out 4 new disks.
4. Install 4 disks from point 1.
Will the controller remember the old RAID 10? Will these actions destroy it?

Thank you!

Answer 1

raid metadata should be stored on hard drives. if this is the case and the controller can import a new configuration, then most likely yes, it will work,
but if the purpose of such gestures is backup, then it’s better to do it by other means

Answer 2

Pull out the discs and sign them - who was in which basket. Usually controllers can read the metadata and build the array themselves, but it's better to play it safe just in case.

Answer 3

At least LSI controllers can do this for sure, but! It is important to keep order, and it is important to have backups. In general, for a test environment, at the very least it will do, for a combat one - well, it’s not worth it at all. The second nuance is that if the hypervisor is not on an array, it may not appreciate such a feint with its ears and may not recognize old disks.
