I started to ask this question once before, but didn't follow up.
I have a zpool that looks like this:
[root@LEI-SmartOS ~]# zpool status
pool: zones
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
zones ONLINE 0 0 0
mirror-0 ONLINE 0 0 0

These drives are sitting in a Supermicro 2U 12-bay chassis with
a BPN-SAS-825TQ SAS/SATA Backplate
My SAS/SATA controllers are 2 x IBM SERVERAID M1015 crossflashed to IT mode
(i.e., pass-through).
I've wired the IBM M1015's to the backplate in what I believe is the
correct order so the drive bay numbers on the backplate match the drive
order on the raid card. However, I'm not entirely sure how to verify this.
Question: What is the best way for me to know where a failed drive is
located in the chassis? Perhaps the backplate/raid card are smart enough
to light up the red error LED when a drive fails, but I'm not certain of
this.
Thanks,
Greg
