The error message "groups(): Driver '' is not available" has been generated
by scstadmin. Apparently a target driver module that should have been loaded
wasn't loaded. I see only one possible cause for this, namely that scst.conf
was hand-edited and some other separator had been used than a single space
in the "TARGET_DRIVER" lines. scst.conf parsing has been relaxed in r3568 on
the trunk. Does that help ?

Mark maintains scstadmin. I'm not sure how far Mark got with implementing
ALUA support in scstadmin.
