3.6.6 Logical Unit
“Logical unit” can be used to view the status of attached logical unit number of each
VD, or can be used to attach or detach a LUN.
User can attach LUN by clicking the “
”. In the “Host” field, user
must enter an iSCSI node name for access control, or fill-in wildcard “*”, which means
every host can access the volume. Choose LUN number and permission, then click
“
”.
VD-01 is attached to LUN 0 and every host can access. VD-02 is attached to LUN 1 and
only initiator node which is named “iqn.1991-05.com.microsoft:demo” can access.
 LUN operations description:
Attach Attach a logical unit number to a Virtual disk.
Detach Detach a logical unit number from a Virtual disk.
The matching rules of access control are inspected from top to bottom in sequence. For
example: there are 2 rules for the same VD, one is “*”, LUN 0; and the other is
“iqn.host1”, LUN 1. The other host “iqn.host2” can login successfully because it
matches rule 1.
The access will be denied when there is no matching rule.
