When I use "cfgadm -a" it only seems to list usb devices?
#cfgadm -a
Ap_Id Type Receptacle Occupant Condition
usb2/1 unknown empty unconfigured ok
usb2/2 unknown empty unconfigured ok
usb2/3 unknown empty unconfigured ok
usb3/1 unknown empty unconfigured ok
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
