SETTING UP LINUX ISCSI INITIATORS

For the example used in this configuration, the following items should be noted:

• The Red Hat Linux initiator has an iSCSI card that uses IP addresses 192.168.10.119 and

192.168.11.119.

• The target is ION Accelerator in HA mode. Each node has a card installed and configured for

iSCSI. The IP addresses are 192.168.10.8 and192.168.11.8 for the first node, and
192.168.10.9 and 192.168.11.9 for the second node.

• An ION Accelerator volume of 100GB is used, with LUNs already created and presented to

the Linux initiator.

Each initiator iSCSI port should be in a separate subnet that is the same as that of the target
iSCSI port.

Discovering and Accessing an ION Accelerator Volume

By running the

targets

command in the CLI, you can view the targets as seen from the HA side of

an ION Accelerator system.

targets -dt --cluster
