Dell 3000i manual If you are using a Linux Server, Iscsicli SessionList

Page 56

To view active sessions to the target, use the following command:

iscsicli SessionList

To support storage array controller failover, the host server must be connected to at least one iSCSI port on each controller. Repeat step 3 for each iSCSI port on the storage array that you want to establish as a failover target. (The Target_Portal_Address will be different for each port you connect to).

PersistentLoginTarget does not initiate a login to the target until after the system is rebooted. To establish immediate login to the target, substitute LoginTarget for PersistentLoginTarget.

NOTE: Refer to the Microsoft iSCSI Software Initiator 2.x User’s Guide for more information about the commands used in the previous steps. For more information about Windows Server 2008 Server Core, refer to the Microsoft Developers Network (MSDN). Both resources are available at www.microsoft.com.

If you are using a Linux Server

If you configured CHAP authentication in the previous steps, you must restart iSCSI from the Linux command line as shown below. If you did not configure CHAP authentication, you do not need to restart iSCSI.

/etc/init.d/iscsi restart

Verify that the host server is able to connect to the storage array by running the iscsi -ls command as you did in target discovery. If the connection is successful, an iSCSI session will be established to each iSCSI port on the storage array.

Sample output from the command should look similar to this:
