Destroy ZFS Dataset with a dataset is busy error

Overview

I had this issue removing zfs dataset on an OpenSolaris file server. The dataset I was trying to remove was data/vi-san-1, which was a shared ISCSI target.

The Error

Sun Microsystems Inc. SunOS 5.11 snv_111b November 2008
root@atlas:~# zfs list

Stopping the ISCSI Services

I manaully stopped the iscsi services to ensure that there are no clients (initiators) connected to this iscsi target

root@atlas:~# svcadm  disable svc:/system/iscsitgt:default

Verify that the iscsi services have stopped:

root@atlas:~# svcs -a | grep iscsi
disabled Jun_11 svc:/network/iscsi_initiator:default
disabled 13:12:16 svc:/system/iscsitgt:default

Volume Registration in the ISCSI Services

Delete the registration with the iscsi services for the volume.
