Create two new iSCSI Authentication profiles, this one is for inbound and I created another outbond, this needs to be configured on your storage array also.
From your Boot Policy, click on Set iSCSI Boot Parameters and select the Inbound CHAP Authentication Profile from the drop down box.
You can also create a policy here if you haven’t already done this separately from the “Create iSCSI Authentication Profile” link.
Once In Bound CHAP is set we need to set the Out Bound CHAP on each iSCSI target, select your target and click the modify button as highlighted below
Set the Out Bound Authentication profile or create one on the link below
