LUN masking considerations

The node WWN and port WWN of the local switch are used to query LUNs on the physical target. If

the physical target uses LUN masking to control access, these WWNs must be added to the LUN

masking to ensure that the LUN query returns the LUNs to the switch.

You can obtain these WWNs in either of two ways.

• Enter the iscsiCfg --easycreate tgt command with the -s option. The -s option returns the node

and port WWNs of the switch.

The following is an example.

switch:admin> iscsicfg --easycreate tgt -s

The following WWNs will be used for any easycreate operation from this switch:

Node WWN: 10:00:00:60:69:80:04:4a

Port WWN: 21:fd:00:60:69:80:04:4a

• Enter the fcLunQuery with the -s option. The -s option returns the node and port WWNs of the

switch.

The following is an example.

switch:admin> fclunquery -s

The following WWNs will be used for any lun query from this switch:

Node WWN: 10:00:00:60:69:80:04:4a

Port WWN: 21:fd:00:60:69:80:04:4a
