Creating Discovery Domains And Domain Sets - HP A7990A - StorageWorks SAN Director 4/16 Blade Switch Hardware Reference Manual

iSCSI node name in readable notation. The name always starts with "iqn" and includes the uses Internet
domain and the year and month on which the Internet domain was assigned:
iqn.yyyy-mm.<reverse of DNS>:<optional unique SCSI string>
Below is an example of a virtual target node name which follows the above naming convention, not
including the optional SCSI string):
Example:
iqn.2005-10.com.company:tgt1
iscsicfg [--create | --modify | --delete | --clear | --show | --commit] tgt args
To create a virtual target, use the iscsicfg --create command with the -tgt and -t operands:
switch:admin> iscsicfg –-create tgt –t iqn.2005-10.com.company:tgt1
Operation Succeeded
After creating the iSCSI target, add the FC devices and the corresponding LUNs to it as follows:
iscsicfg [--add] lun -t target_name -w fc_wwn -l LUN_map args
Then verify the addition of devices and LUNs:
iscsicfg [--show] lun -t target_name
Use the fcLunQuery command to find out which LUNs are available to add to the iSCSI target:
The list of available FC targets in the fabric with the LUN configuration can be displayed using the
fcLunQuery command, which lists the LUN IDs of the LUN(s) that are exposed. The WWN argument is
optional. If no argument is specified, LUNs for all accessible targets in the fabric are displayed. You can
specify either port or node WWNs.
fclunquery [-w wwn]
To view the available LUNs, use the fcLunQuery command:
switch:admin> fclunquery
Target Index: 1
Target Node WWN: 50:05:07:65:05:03:f9:39
Target Port WWN: 50:05:07:65:05:83:f9:39
Target Pid: 144e8
Number of LUNs returned by query: 1
LUN ID: 0x00
Once you have the port WWN of the LUN you want to add to the iSCSI target, you can add the LUN map
to the target with the specified target name. FC WWN provides the port WWN of the physical FC target
and the LUN map maps the physical FC LUNs to virtual iSCSI LUNs. The LUN mapping is specified as a
pair: virtual LUNs:physical LUNs
To add a Fibre Channel device to an existing virtual target, use the iscsicfg --add command with the
-tgt and -t operands:
switch:admin> iscsicfg –-add lun –t iqn.2005-10.com.brocade.tgt1 –w
22:00:00:04:cf:20:5d:33 –l 0:0
Operation Succeeded
Once the iSCSI target configuration is committed to the configuration database, the iSCSI target will be
accessible to the iSCSI host during the discovery process.

Creating discovery domains and domain sets

Discovery domains are analogous to zones and discovery domain sets are analogous to zone sets. When
there are no discovery domain or discovery domain sets defined, then all the iSCSI hosts have access to all
iSCSI targets.
