Chapter 24 Configuring IP Storage
Choose IP > iSCSI from Device Manager. You see the iSCSI dialog box.
Step 1
Choose the Targets tab to display a list of existing iSCSI targets.
Step 2
Click Create to create a new iSCSI target. You see the Create iSCSI Targets dialog box.
Step 3
Step 4 Set the iSCSI target node name in the iSCSI Name field, in IQN format.
Step 5 Set the port WWN for the Fibre Channel target port you are mapping.
Click the List radio button and set the iSCSI initiator node names or IP Addresses that you want this
Step 6
virtual iSCSI target to access, or click the All radio button to let the iSCSI target access all iSCSI
initiators. See the
Step 7 Click the Selected from List radio button and check each interface you want to advertise the iSCSI
targets on or choose the All radio button to advertise all interfaces.
Step 8 Click Apply to save this change or click Cancel to close the dialog box without saving any changes.
For multiple interfaces configured with iSNS, a different static virtual target name has to be created for
each interface tagged to an iSNS profile and each static virtual target must be advertised only from one
interface.
Advertising iSCSI Targets
You can limit the Gigabit Ethernet interfaces over which static iSCSI targets are advertised. By default
iSCSI targets are advertised on all Gigabit Ethernet interfaces, subinterfaces, PortChannel interfaces,
and PortChannel subinterfaces.
High Availability Static Target Importing
Statically imported iSCSI targets have an additional option to provide a secondary pWWN for the Fibre
Channel target. This can be used when the physical Fibre Channel target is configured to have an LU
visible across redundant ports. When the active port fails, the secondary port becomes active and the
iSCSI session switches to use the new active port (see
