4.6.5 Logical unit number
Enter “Logical unit” function to view the status of attached logical unit number of each UDV
You can add LUN by clicking the “ ”. The confi guration screen will show, as in Figure
4.6.5.1 You must input an initiator name in the “Host” fi eld for access control, or fi ll-in wildcard “”, which
allow every host can control the volume. Choose LUN and permission, click “
” as
shown in Figure 4.6.5.2.

LUN operations description:
ATTACH Attach a logical unit number to a user data volume
DETACH Detach a logical unit number from a user data volume
The authorization rules of access control are applied in top-down order. For example: there are two rules
for the same UDV, one is “*” for LUN 0 and the other is “iqn.host1” for LUN 1. A different host “iqn.host2”
is allowed to login to have access control because the rule one allow access for all host.
The access will be denied when there is no matching rule.
4.6.6 Example
The followings are examples for creating a volume. Example 1 is to create two UDVs sharing the same
CV (global cache volume) and confi gure a global spare disk. Example 2 is to create two UDVs. One
shares global cache volume while the other uses dedicated cache volume. A dedicated spare disk will
be confi gured.
Example 1
Example 1 is to create two UDVs in one VG, each UDV shares global cache volume. Global cache
volume is automatically created after system boots up, therefore no action is needed to confi gure CV.
Finally, set a global spare disk. The last protion will show how to delete all confi gurations.
