I follow those steps: Only if all CHAP auth is the same for all targets, in which case you can specify the user/pass pairs in /etc/iscsi/iscsid.conf Otherwise, you have to configure individual targets via iscsiadm. I like your use of environment variables to specify targets and portals (though I believe the default port is used if unspecified). I'd arrived at the same convention myself. And though I'd turned up the authmethod assignment method somewhere, I can't for the life of me remember where -- neither the iscsi-initiator-utils document (README) nor the iscsiadm manpage seem to address this -- they're otherwise pretty good.
