Dell MD3220i, MD3200i manual Source Port Selection for iSCSI Host Ports

Page 46

7In the Storage Array Login screen, in the Controller# column, select the iSCSI host port of the storage array that needs to be configured and its IP address(es). In the Host Address column, from drop-down menu list, select the host IP address that logs into the iSCSI host port of the storage array.

See "Source Port Selection for iSCSI Host Ports" on page 46 for more details about how these host IP addresses are listed in the drop-down menu and the recommended guidelines for selecting the host IP addresses.

Click Next to continue to enter the login information for another controller or Click Apply to commit the array login information.

8In the Connect to Additional Arrays screen, select whether you want to connect to another storage array or not.

If you want to connect to another storage array, repeat the above steps starting from step 4 or step 5 depending on your last selection.

If you do not want to connect to additional arrays, then click Finish on the final screen to exit the utility.

Source Port Selection for iSCSI Host Ports

In order to establish data communication between a host and an iSCSI-based storage array, the iSCSI initiator on the host must be configured to establish iSCSI sessions to the iSCSI host ports of the storage array. The iSCSI port login screen allows you to specify the host and storage array IP addresses the iSCSI initiator uses to establish these iSCSI sessions.

Port Login Selection

Each iSCSI port for each controller in the storage array is presented with a list of host IP addresses through which the iSCSI initiator is able to login. The host IP addresses are the source IP addresses and the iSCSI port is the target.

Each list contains only the host IP addresses that are able to communicate with the associated iSCSI port. If none of the host IP addresses are able to communicate with an iSCSI port, Not Available is the only option shown for that iSCSI port. If none of the host IP addresses are able to communicate with any iSCSI ports of either storage array controller, the host configuration option is aborted for that storage array.

NOTE: The behavior described in the preceding paragraph does not apply to Microsoft Windows Server 2003.
