HP strongly recommends configuring all iSCSI-based storage for application servers on a dedicated

network bandwidth for storage as well as increased security.

To configure storage networks for iSCSI traffic:

1.

Under Preferred Storage Network, select a network that will be designated to manage all
iSCSI traffic.

2.

Under Available for Failover, select a network that can be used to manage iSCSI traffic in the
event that the preferred storage network fails. In the event of iSCSI initiator failure, iSCSI traffic
fails over to the designated network.

NOTE:

Any existing iSCSI connections must be reset before changes take effect.
