[zfs-discuss] how do I revert back from ZFS partitioned disk to original partitions
I accidentally created a zpool on a boot disk, it paniced the system and now I can jumpstart and install the OS on it. This is what it looks like. partition> p Current partition table (original): Total disk sectors available: 17786879 + 16384 (reserved sectors) Part Tag Flag First Sector Size Last Sector 0 usr wm 34 8.48GB 17786879 1 unassigned wm 0 0 0 2 unassigned wm 0 0 0 3 unassigned wm 0 0 0 4 unassigned wm 0 0 0 5 unassigned wm 0 0 0 6 unassigned wm 0 0 0 8 reserved wm 17786880 8.00MB 17803263 partition> ========================I want to go back to this. partition> p Current partition table (original): Total disk cylinders available: 17660 + 2 (reserved cylinders) Part Tag Flag Cylinders Size Blocks 0 root wm 1041 - 16597 7.48GB (15557/0/0) 15681456 1 swap wu 0 - 1040 512.37MB (1041/0/0) 1049328 2 backup wm 0 - 17659 8.49GB (17660/0/0) 17801280 3 unassigned wm 0 0 (0/0/0) 0 4 unassigned wm 0 0 (0/0/0) 0 5 unassigned wm 0 0 (0/0/0) 0 6 unassigned wm 16598 - 17638 512.37MB (1041/0/0) 1049328 7 unassigned wm 17639 - 17659 10.34MB (21/0/0) 21168 partition>

Arif,
You need to boot from {net | DVD} in single-user mode, like this:
boot net -s or boot cdrom -s
Then, when you get to a shell prompt, relabel the disk like this:
# format -e
<select disk>
format> label
[0] SMI Label
[1] EFI Label
Specify Label type[0]: 0
Then, you should be able to repartition however you want.
