NOTE:

If you are using the PowerVault NX1950 cluster solution configured with

Target 3.0 iSCSI Target software, you must add a virtual iSCSI IP that is part of the

Cluster Resource in the Target Portals field. This IP address must be a virtual IP

address in the same subnet where iSCSI NICs are configured. This ensures proper

connection between Initiator and Targets during cluster node failover or during

Cluster Group move among different nodes of cluster. This configuration also

ensures that iSCSI I/O traffic is not transmitted on the public network.

NOTE:

If you are using PowerVault NX1950 cluster solution configured with 3.1

iSCSI Target software, you must create at least one iSCSI HA instance on each

node and use the IP address of the iSCSI HA instance for iSCSI traffic. This ensures

Active/Active Initiator-Target connection (connection with targets created on all

nodes of cluster) and high-availability. If one node fails, the surviving node or the

node that owns the cluster group takes over and owns all iSCSI Targets (targets of

its own and targets of failed node) and the iSCSI I/O operations.

iSNS Servers—You can also perform Target discovery using iSNS servers. Add

the iSNS Server IP address or DNS name. If the iSNS service is up and running

on a server, all clients (Initiators and Targets) that are registered with the iSNS

server are listed in the Registered Clients screen. To retrieve this information

on the iSNS server, go to Microsoft iSNS properties→ Registered Clients.
