iSCSI Virtual Target Configuration
Configuring an iSCSI environment involves creating iSCSI virtual targets (VTs), discovery domains (DDs),
discovery domain sets (DDSets), and defining iSCSI VT-iSCSI initiator authentication.
NOTE:
You can also configure iSCSI virtual targets through the Web Tools Graphical User Interface as an
alternative to the command line interface. See the
Web Tools Administrator’s Guide
for descriptions of
GUI-based configuration procedures.
You create iSCSI VTs using the LUN values of FC targets. The FC target must be accessible from the iSCSI
gateway. iSCSI VTs can be automatically generated or manually created.
After mapping iSCSI targets
do not move the targets out of Administrative Domain 0 (AD0)
, unless you
then explicitly add them back to AD0.
Automatic iSCSI VT creation
An iSCSI VT is created using target LUNs from the attached FC network. LUNs are mapped to iSCSI VTs by
creating unique iSCSI Qualified Names (IQNs) for each target.
You can create iSCSI VTs by using the
iscsiCfg
--
easycreate tgt
command. There are two
options:
An iSCSI VT may be created for every FC target. IQNs are created automatically, using the port
WWNs as the user defined portion of the IQN.
A port WWN may be specified to create one ISCSI VT with all LUNs for that FC target. The WWN of
the FC target is used as the user defined portion of the IQN.
Generating iSCSI VTs for every FC target
1.
Connect and log in to the switch.
2.
Enter the
iscsiCfg
--
easycreate tgt
command with no options.
The command returns a prompt indicating that this could be a long running operation.
3.
Enter
y
or
yes
to continue. IQNs are created. The default value of
iqn.2002-12.com.brocade
, is
used for the prefix unless it has been changed by using the
iscsiSwCfg - -modifygw -t
<
tgtname
>
command. The port WWN is used as the user-defined portion of the IQN.
The following is an example:
