To support storage array controller failover, the host server must be
connected to at least one iSCSI port on each controller. Repeat step 3
through step 8 for each iSCSI port on the storage array that you want to
establish as failover targets (the
Target Port a l
address is different for each
port you connect to).
The

Viewing the Status of Your iSCSI Connections
In MD Storage Manager, click the iSCSI tab and then Configure iSCSI Host
Ports to view the status of each iSCSI port you attempted to connect to and
the configuration state of all IP addresses. If either Disconnected or
Unconfigured is displayed, check the following and repeat the iSCSI
configuration steps:
• Are all cables securely attached to each port on the host server and
storage array?
• Is TCP/IP correctly configured on all target host ports?
• Is CHAP set up correctly on both the host server and the storage array?
