Hua-Ying,
The partition table *is* confusing so don't try to make sense of it. :-)
Partition or slice 2 represents the entire disk, cylinders 0-24317.
You created slice 0, which is cylinders 1-24316. Slice 8 is a reserved,
legacy area for boot info on some x86 systems. You can ignore it.
Looks like a reasonable partition setup to me.
As long as the partition tables for your c3d0 and c3d1 disks are similar
you should be able to attach the disk, like this:
# zpool attach rpool c3d0s0 c3d1s0
Don't forget to add the bootblocks to c3d1s0 as described in the
troubleshooting wiki.

I'm confused by the output of the partition command, this is the

current partition table (original):

5 unassigned wm 0 0 (0/0/0) 0
6 unassigned wm 0 0 (0/0/0) 0
7 unassigned wm 0 0 (0/0/0) 0
8 boot wu 0 - 0 7.84MB (1/0/0) 16065
9 unassigned wm 0 0 (0/0/0) 0
It seems like the partition 0,2,8 are sharing the same part of the
disk. How is this possible?

Hi Hua-Ying,
Some disks don't have target identifiers, like you c3d0
and c3d1 disks.
To attach your c3d1 disk, you need to relabel it with an
SMI label and provide a slice, s0, for example.
See the steps here:

P.S. For cfgadm output, you might need to use the cfgadm -al or maybe
-av syntax. The options/output of this command might depend on the hardware
types. I'm not quite sure what it needs in this case.

When I use "cfgadm -a" it only seems to list usb devices?

I'm trying to convert a nonredundant storage pool to a mirrored pool.
I'm following the "zfs admin guide" on page 71.
I currently have a existing rpool:
#zpool status
pool: rpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c3d0s0 ONLINE 0 0 0
I want to mirror this drive, I tried using format to get the disk name
#format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c3d0 <DEFAULT cyl 24318 alt 2 hd 255 sec 63>
/p...@0,0/pci-...@14,1/i...@0/c...@0,0
1. c3d1 <drive type unknown>
/p...@0,0/pci-...@14,1/i...@0/c...@1,0
So I tried
#zpool attach rpool c3d0s0 c3d1s0 // failed
cannot open '/dev/dsk/c3d1s0': No such device or address
#zpool attach rpool c3d0s0 c3d1 // failed
cannot label 'c3d1': EFI labeled devices are not supported on root pools.
Thoughts?
Thanks,
Hua-Ying

How do I discover the disk name to use for zfs commands such as:
c3d0s0? I tried using format command but it only gave me the first 4
letters: c3d1. Also why do some command accept only 4 letter disk
names and others require 6 letters?
Usually i find
cfgadm -a
helpful enough for that (mayby adding '|grep disk' to it).
Why sometimes 4 and sometimes 6 characters:
c3d1 <- this would be disk#1 on controller#3
c3d0s0 <- this would be slice #0 (partition) on disk #0 on controller #3
Usually there is a also t0 there, e.g.:
cfgadm -a|grep disk |head
sata0/0::dsk/c0t0d0 disk connected configured ok
sata0/1::dsk/c0t1d0 disk connected configured ok
sata0/2::dsk/c0t2d0 disk connected configured ok

sata0/4::dsk/c0t4d0 disk connected configured ok
sata0/5::dsk/c0t5d0 disk connected configured ok
sata0/6::dsk/c0t6d0 disk connected configured ok
sata0/7::dsk/c0t7d0 disk connected configured ok
sata1/0::dsk/c1t0d0 disk connected configured ok
sata1/1::dsk/c1t1d0 disk connected configured ok
