solaris 10 errors mount external usb Harddisk zfs on a nas without cdrom

Hi,

I try to mount an external USB HD on a solaris 10 without any success.

Machine hardware: i86pc
OS version: 5.10
Processor type: i386
Hardware: i86pc

The HD is a zfs, but I installed this with a Ubuntu 8.10.

iostat -En displays this:

--> so the system sees this HD.

I tryed all the following, without any success:

zpool import

mount -F ufs /dev/dsk/c8t0d0p1 /mnt

mount -F zfs /dev/dsk/c8t0d0p1 /mnt

mount -F zfs /dev/dsk/c8t0d0 /mnt

df -k

mount -F pcfs /dev/dsk/c2t0d0p0:c /rmdisk

/etc/init.d/volmgt stop
/etc/init.d/volmgt start
--> does not help.

Cannot run a live cd because this sun does not have a reader.

Can anyone help me please?
