(Figure 3.6.6.2: UDV-01 is attached to LUN 0 with every host can access. UDV-02 is
attached to LUN 1 with only initiator note named “iqn.1991-05.com.microsoft:s1300n” can
access.)
• 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 matching rules of access control are from top to down by sequence. For
example: there are 2 rules for the same UDV, one is “*”, LUN 0; the other is
“iqn.host1”, LUN 1. The other host “iqn.host2” can login because it matches the
rule 1.
The access will be denied when there is no matching rule.
3.6.7 Examples
The followings are examples for creating volumes. Example 1 is to create two
UDVs sharing the same CV (global cache volume) and set a global spare disk.
