# Usage: block-iscsi [add tgtname | remove dev]

# This assumes you're running a correctly configured
|

# iscsi target (server) at the other end!

# Note that we assume that the passwords for discovery (if needed)
|
|
# are in /etc/iscsid.conf
|
|
# and the node session passwords (if required) in the
|
|
# open-iscsi database below /var/lib/open-iscsi/node.db
