[OmniOS-discuss] SSD rpool degraded

[Johan Kragsterman]

Hi!

I got a degraded rpool, consisting of a mirror of two SSD's. I feel unsure about if it really is the SSD that have failed, since it is enterprise grade and haven't been running that long

I would like to know if there is a way to figure out wether it is the SATA port or the SSD that have failed.

The zpool status looks like this:

NAME          STATE     READ WRITE CKSUM
        rpool         DEGRADED     0     0     0
          mirror-0    DEGRADED     0     0     0
            c2t0d0s0  ONLINE       0     0     0
            c2t1d0s0  FAULTED      1   191     0  too many errors



dmesg containes this:

>From that it looks like zfs hinting that it is the device, not the port...

But with cfgadm I get unsure again...

Someone know...?
