• LUN operation description: Attach Detach Attach a logical unit number to a virtual disk. Detach a logical unit number from a virtual disk. The matching rules of access control are followed from the LUN' 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?"  "iqn.host1" and "iqn.host2" are accepted. "iqn.host*"  "iqn.host1" and "iqn.host12345" are accepted. This field can not accept comma, so "iqn.host1, iqn.host2" stands a long string, not 2 iqns. 4.4.6 Example The following is an example to create volumes. This example is to create two VDs and set a global spare disk. • Example This example is to create two VDs in one RG, each VD shares the cache volume. The cache volume is created after system boots up automatically. Then set a global spare disk. Last, delete all of them. Step 1: Create a RG (RAID group).

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 LUN’ 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?”
“iqn.host1” and “iqn.host2” are accepted.
“iqn.host*”
“iqn.host1” and “iqn.host12345” are accepted.
This field can not accept comma, so “iqn.host1, iqn.host2” stands a long string, not 2 iqns.
