Andreas,

Does the pool tank actually have 6 disks c7t0-c7t5 and c7t3d0 is now
masking c7t5d0 or it is a 5-disk configuration with c7t5 repeated twice?
If it is the first case (c7t0-c7t5), then I would check how these
devices are connected before attempting to replace the c7t3d0 disk.

What does the format utility display for these devices?

I haven't seen this error but others on this list have resolved this
problem by exporting and importing the pool.

Always have good backups of your data.

Thanks,

Cindy

Hi there,
My zpool tank has been chugging along nicely but after a failed attempt at offlining a misbehaving drive I've got a wierd sitation. pool: tank
 state: DEGRADED
status: One or more devices has been taken offline by the administrator.
        Sufficient replicas exist for the pool to continue functioning in a
        degraded state.
action: Online the device using 'zpool online' or replace the device with
        'zpool replace'.
 scrub: none requested

Why does that particular drive appear twice? I am on SNV_134. They are 6x500Gb Western Digital RE drives. I have a spare 500Gb on another controller (c0t0d0) which I want to use to keep replace the (probably dying) drive but I'm not sure I can do this and it will correctly remove the one I want:

# zpool replace tank c7t3d0 c0t0d0
Any ideas? Gracias,
Andre
