Configuring discovery domain sets
You can create four discovery domain sets, but only one set can be enforced at a time. Discovery
domain sets allow you to enable and disable fabric-wide iSCSI VT access with a single command.
To create and activate a DDSet, complete the following procedures:
• “Creating a DDSet”
• “Enabling a DDSet”
Creating a DDSet
To create a discovery domain set, use the iscsiCfg --create ddset command with the -n and -d
options:
To create a new DD set
1. Connect and log in to the switch.
2. Enter the iscsiCfg
--create ddset command with the -n and -d options as follows:
switch:admin> iscsicfg --create ddset -n ddset-engineering -d dd-host001
The operation completed successfully.
3. To verify the DDSet, enter the iscsiCfg --show ddset command with the -v option as follows:
switch:admin> iscsicfg --show ddset -v

Enabling a DDSet
An enabled DDSet is enforced fabric-wide. In a deployment with an active DDSet, only iSCSI
initiators in an enforced DD can access iSCSI VT in the same DD.
To enable a DD set
1. Connect and log in to the switch.
2. Enter the iscsiCfg
--enable ddset command with the -n option as follows:
switch:admin> iscsicfg --enable ddset -n ddset-engineering
This will enable the DDSet specified.
Continue (yes, y, no, n) [n]: y
The operation completed successfully.
