I have attached the wire shark trace for OneWay-CHAP and Mutual-CHAP. I am
not sure how helpful this is.

In case of OneWay-CHAP, Open-iscsi initiator does not continues with the
login step and gives and error as follows:

Logging in to [iface: default, target: iqn.2008-07.com.wasabi:osd.1, portal:,3260]
iscsiadm: Could not login to [iface: default, target:
iqn.2008-07.com.wasabi:osd.1, portal:,3260]:
iscsiadm: initiator reported error (5 - encountered iSCSI login failure)
Target discovery or login failed

BTW, Microsoft initiator works fine with OneWay-CHAP and Mutual-CHAP with
our target. So I think it something subtle.
Thx, Arvind.

Actually not sure about Equallogic. I think we just tested one way. I am 
not sure if we tested 2 way.
