Configure virtual IP and iSNS for iSCSI

VIPs are required for iSCSI load balancing and fault tolerance and for using HP DSM for MPIO. For
more information, see

Using Virtual IP addresses

Virtual IP (VIP) addresses are required for all clusters in SAN/iQ software versions 8.0 and higher.
1. Click the iSCSI tab to bring it to the front.
Because a VIP is required in release 8.0 and greater, the choice to use a virtual IP is disabled
by default in the 8.0 CMC. If you have management groups that are running 7.0 or earlier
software, the choice to use a VIP remains enabled.
2. Add the IP address and subnet mask.

Adding an iSNS server

(Optional) Add an iSNS server.
NOTE:
If you use an iSNS server, you may not need to add Target Portals in the Microsoft iSCSI Initiator.
1. In the iSCSI tab view, click the iSCSI Tasks menu, and select Add iSNS Server.
The Add iSNS Server window opens.
2. Enter the IP address of the iSNS server.
3. Click OK.
4. Click OK when you have finished.
The cluster is created and displayed inside the management group.
5. Select the cluster to open the Clusters tab window.
