4.4.5 Logical unit
“Logical unit” can view, create, and modify the status of attached logical unit
number(s) of each VD.
User can attach LUN by clicking the “Attach”. “Host” must enter with an iSCSI node
name for access control, or fill-in wildcard “*”, which means every host can access
the volume. Choose LUN number and permission, and then click “Confirm”.

Figure 4.4.5.2
(Figure 4.4.5.2: VD-01 is attached to LUN 0 and every host can access. VD-02 is attached to
LUN 1 and only the initiator node which is named “iqn.1991-05.com.microsoft:iStoragePro” can
access.)
LUN operation 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 followed from the LUNs’ created time; the
earlier created LUN is prior to the matching rules. For example: there are 2 LUN rules
for the same VD, one is “*”, LUN 0; and the other is “iqn.host1”, LUN 1. The host
“iqn.host2” can login successfully because it matches the rule 1.
Wildcard “*” and “?” are allowed in this field. “*” can replace any word. “?” can replace
only one character. For example:
“iqn.host?” Æ “iqn.host1” and “iqn.host2” are accepted.
“iqn.host*” Æ “iqn.host1” and “iqn.host12345” are accepted.
