zfs discuss - Feb 2013 - Disk Unavailable

I am trying to replace a failed disk on my zfs system.
I replaced the disk and while the physical drive status is now OK, my logical
drive is still failed.
When I do a zpool status, the new disk comes up as unavailable:
            spare       DEGRADED     0     0     0
              c9t17d0   UNAVAIL      0     0     0  cannot open
              c9t23d0   ONLINE       0     0     0

And when I try to replace the disk I get the following errors:


root at xxxxxx:/usr/local/scripts# zpool online data c9t17d0
warning: device ''c9t17d0'' onlined, but remains in faulted
state
use ''zpool replace'' to replace devices that are no longer
present

root at xxxxx:/usr/local/scripts# zpool replace data c9t17d0
cannot open ''c9t17d0'': no such device in /dev/dsk
must be a full path or shorthand device name

This is the second disk I have used as a replacement and I am getting the same
errors with both new disks.  I am new to all of this and am NOT a sys admin! 
Please help!

Hi Kiley,

Can you post the listing of the "format" command?
It should print something like:

Searching for disks...done

AVAILABLE DISK SELECTIONS:
       0. c9t0d0 <ATA-WDCWD5003ABYX-1-1S02 cyl 60797 alt 2 hd 255 sec 63>
          /pci at 0,0/pci1028,28c at 1f,2/disk at 0,0
       1. c9t1d0 <ATA-WDCWD5003ABYX-1-1S02 cyl 60797 alt 2 hd 255 sec 63>
          /pci at 0,0/pci1028,28c at 1f,2/disk at 1,0
Specify disk (enter its number):

(Just hit Control-C to return back to the command line.)

This should give you a listing of all the drives you have available on
your machine. If c9t17d0 isn''t there, then there''s a good
chance that
you''ll need to run something like "devfsadm -c disks" to
force a SCSI
bus rescan (to discover new drives).

Cheers,
