Hi.
I have a disk in my pool that shows signs of failures.

As you can see, my zones pool is configured as a striped mirror.
I would like to replace the faulty disk with a new one (exact same model).
This is what I am planning on doing:
# zpool offline c4t5000CCA012B12465d0
- shutdown the machine
- replace the drive
- boot
# zpool replace zones c4t5000CCA012B12465d0 <my-new-drive>
I've never done it before so I have 2 questions to ensure I am not doing
anything wrong or stupid here.
1. is what I proposed (offline+replace) correct?
2. the new drive will probably have another device name, won't it? If so, won't
I get into problem if I use the replace command with c4t5000CCA012B12465d0 which
will probably not exist anymore (since that disk got replaced)?
Thank you very much for any hint.
