Configuring iSLB Using Device Manager

Prerequisites

Perform the following actions prior to configuring iSLB:

• Enable iSCSI (see the "Enabling iSCSI" topic for more information).
• Configure the Gigabit Ethernet interfaces (see the "Configuring Gigabit Ethernet Interface" topic).
• Configure the VRRP groups (see the "Configuring Load Balancing Using VRRP" topic).
• Configure and activate a zone set (see the Fabric Configuration Guide, Cisco DCNM for SAN for more information).
• Enable CFS distribution for iSLB (see the "Enabling iSLB Configuration Distribution" topic).

Detailed Steps

To configure iSLB using Device Manager, follow these steps:

1. Choose IP > iSCSI iSLB.

You see the iSCSI iSLB dialog box.

2. Click Create to create a new iSCSI iSLB initiator.

You see the Create iSCSI iSLB Initiators dialog box.

3. Set the Name or IP Address field to the iSLB name or IP address.
4. Set the VSAN Membership field to the VSAN that you want the iSLB initiator in.

Also see the "Assigning VSAN Membership for iSLB Initiators" topic.

5. Check the Persistent check box to convert a dynamic nWWN to static for the iSLB initiator.

Also see the "Making the Dynamic iSCSI Initiator WWN Mapping Static" topic.

6. (Optional) Check the SystemAssigned check box to have the switch assign the nWWN.
7. (Optional) Set the Static WWN field to manually assign the static nWWN. You must ensure uniqueness for this nWWN.
8. (Optional) Check the Port WWN Mapping Persistent check box to convert dynamic pWWNs to static for the iSLB initiator.

See the "Making the Dynamic iSCSI Initiator WWN Mapping Static" topic.

9. (Optional) Check the SystemAssigned check box and set the number of pWWNs you want to have the switch assign the PWWN.
10. (Optional) Set the Static WWN(s) field to manually assign the static pWWNs.

You must ensure uniqueness for these pWWN.

1. (Optional) Set the AuthUser field to the username that you want to restrict the iSLB initiator to for iSLB authentication.

Also see the "Restricting iSLB Initiator Authentication" topic.

2. Fill in the Username and Password fields to configure iSLB initiator target CHAP authentication.

Also see the "iSLB Session Authentication" topic.

1. In the Initiator Specific Target section, set the pWWN to configure an iSLB initiator target.
2. (Optional) Set the Name field to a globally unique identifier (IQN).
3. (Optional) Check the NoAutoZoneCreation check box to disable auto-zoning.
4. (Optional) Check the TresspassMode check box.

Also see the "LUN Trespass for Storage Port Failover" topic.

5. (Optional) Check the RevertToPrimary check box to revert back to the primary port after an HA failover when the primary port comes back up.
6. Set the PrimaryVsan to the VSAN for the iSLB initiator target.
7. Click Create to create this iSLB initiator.
8. If CFS is enabled, select commit from the CFS drop-down menu.
