We have a customer with a 25TB R5 array (I know its bad, don't ask, inherited) on an MD1000, drive 14 went out, we replaced with exact brand and model, firmware is very close. Most are 0001, and there are a few SN03 and SN04, this new one in question is SN04.
When we replaced the drive it initialized on the same controller, then a few minutes later it put the drive into the Connector 1, when the rest of the array is in Connector 0. Disk Shows Green in the separate Connector, but we still have an amber light on the drive, and it looks like the drive has a ton of activity.
With seeing varing results I am scared to pull it and try another brand new drive, also being it is R5. Drive was replaced 3 weeks ago, so the rebuild should have been done by now.
Thoughts? HELP!
