To replace failed drive, you can prepare slot and put in new (replacement) drives on dells and it should start scrubbing.

In case it doesn’t start scrubbing (there is a delay, so wait 2min),
 AAC0> container set failover (scsi id of new disk)

Or if that fails

 AAC0> container unmirror 1

That will demote it to a volume,
Then container create, etc…
