6. You are presented with a confirmation panel stating that the CHAP secret has been set successfully. Click OK. You will now be returned to the Mutual Authentication panel as shown in Figure 6-20. We can now see that our host redbooks03_iSCSI has CHAP authentication defined as Permission Set. Figure 6-20 CHAP Mutual Authentication 414 SAN Boot Implementation and Best Practices Guide for IBM System Storage
CHAP authentication using the Initiator Chap Secret has now been set up. You should be able to establish a secure connection between the DS5000 storage subsystem and the host server. Perform the following tasks to configure the boot LUN for your operating system partition: 1. Create a logical volume (LUN) of size that fits your OS system partition requirements: a. In the Storage Manager’s Subsystem Management window, go to the Logical tab. b. Right-click Free Capacity � Create Logical Drive..., as shown in Figure 6-21.
