Bug ID 4370760

Problem Summary: You cannot remove the last host from a metaset unless you first take the device group offline.

Workaround: To remove the last host from a metaset, take the device group offline first. To remove the last host, run the following two commands as superuser from the host to be removed.

# /usr/cluster/bin/scswitch -m -D disksetname
# metaset -s disksetname -d -h hostname
