Create ZONE in ZFS pool solaris10

Question

Hi Gurus,
I'm reading some solaris 10 tutorials about ZFS and Zones. Is it possible to create a new storage pool using my current hard disk in which I installed solaris???
I'm a bit new in Solaris, I have a SPARC box in which I'm learnin about solaris 10. I have installed Solaris 10 using ZFS file system. I think my box only have 1 disk but not sure. I see 46 GB of free space running "df -kh " command
I run "format" command, this is the output
root@orclidm # format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0t0d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
/pci@780/pci@0/pci@9/scsi@0/sd@0,0
1. c0t1d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
/pci@780/pci@0/pci@9/scsi@0/sd@1,0
Specify disk (enter its number):
zpool list "display this:"
root@orclidm # zpool list
NAME SIZE ALLOC FREE CAP HEALTH ALTROOT
rpool 68G 13.1G 54.9G 19% ONLINE -
zfs list "display this:"
root@orclidm # zfs list
NAME USED AVAIL REFER MOUNTPOINT
rpool 21.3G 45.6G 106K /rpool
rpool/ROOT 11.6G 45.6G 31K legacy
rpool/ROOT/s10s_u10wos_17b 11.6G 45.6G 11.6G /
rpool/dump 1.50G 45.6G 1.50G -
rpool/export 66K 45.6G 32K /export
rpool/export/home 34K 45.6G 34K /export/home
rpool/swap 8.25G 53.9G 16K -
I read in a tutorial that when you create a zpool you need to specify an empty hard disk, is that correct?
Please point me on the best approach to create zones using zfs pools.
Regards

This shows two disks. In a production setup you might mirror this.
zpool list "display this:"
root@orclidm # zpool list
NAME SIZE ALLOC FREE CAP HEALTH ALTROOT
rpool 68G 13.1G 54.9G 19% ONLINE -
The command:
zpool status
would show you what devices you are using
zfs list "display this:"
root@orclidm # zfs list
NAME USED AVAIL REFER MOUNTPOINT
rpool 21.3G 45.6G 106K /rpool
rpool/ROOT 11.6G 45.6G 31K legacy
rpool/ROOT/s10s_u10wos_17b 11.6G 45.6G 11.6G /
rpool/dump 1.50G 45.6G 1.50G -
rpool/export 66K 45.6G 32K /export

No.
You can use partions/slices instead. A zone storage pool is composed of one or more devices; each device can be a a whole disk, disk slice or even a file if i remember correctly ( .... but you really dont want to use a file normally).
Please point me on the best approach to create zones using zfs pools.
RegardsYour storage rpool is 68GB in size on a 72GB disk .... therefore the disk is full up and their is no space for another zfs pool. If zpool status shows your disk is mirrored by zfs that is that. Otherwise you may choose to create a storage pool on the other disk (not best production practice).
often one creates a zfs filesystem out of an existing filesystem.
zfs create -o mountpoint=/zones rpool/zones
zfs create rpool/zones/myzone
Then use zonepath=/zones/myzone creating the zone.
- I was googling to cross check my answer ... the following blog has an example but it is a little old and may be opensolaris orientated.
