Required type designator (iqn)
Date code (yyyy-mm)
Reversed domain name (tld.domain)
Any string guaranteeing uniqueness (string[[.string]...])
Optional colon-delimited sub-group string ([:substring])

EXAMPLES
Discover targets at a given IP address:
iscsiadm --mode discoverydb --type sendtargets --portal 192.168.1.10 --discover
Login, must use a node record id found by the discovery:
iscsiadm --mode node --targetname iqn.2001-05.com.doe:test --portal 192.168.1.1:3260 --login
Logout:
iscsiadm --mode node --targetname iqn.2001-05.com.doe:test --portal 192.168.1.1:3260 --logout
List node records:
iscsiadm --mode node
Display all data for a given node record:
iscsiadm --mode node --targetname iqn.2001-05.com.doe:test --portal 192.168.1.1:3260
