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.
Nice docs.
