My 2nd. internal boot drive in my 280R is failing and needs to be
replaced according to metastat command.
Do I have to undo any of the mirrors on the affected disk first?
Do I need to remove the state database from the bad drive first?
The affected metadevice is d5 below but that disk is also part of other
metadevices.
Here is my plan.
1. Pull bad drive (2nd. internal) while system is up and running.
2. Install new drive.
3. Partition new drive to match the primary boot disk in the system now.
4. Issue this command:
metareplace -e d5 c1t1d0s0
Do the above steps look correct or am I missing a step or two?
Or should I shut the system down and then replace the bad drive?
Thank You.
