open-iscsi www.open-iscsi.org

open-iscsi is one of the best iSCSI initiators available with linux. One of the problems with open-iscsi initiator is how to do discovery which requires CHAP authentication

iscsiadm would not allow to specify CHAP authentication attributes without adding the discovery address, and you cannot add a discovery address without doing a successfull discovery which would require CHAP credentials if configured on target side

To Do discovery CHAP authentication with open-iSCSI
-------------------------------------------------------
Edit the /etc/iscsi/iscscid.conf to add the discovery authnetication manually

discovery.sendtargets.auth.username =
discovery.sendtargets.auth.password =

and then use iscsiadm to add the discovery address, it will then use the above CHAP credentials to authenticate with the target
