Red Hat Bugzilla – Bug 922270
unable to pass "--iscsi portal=..." args to tgtd
Last modified: 2013-11-21 17:30:25 EST
Description of problem: /etc/init.d/tgtd does not support command-line arguments to tgtd Version-Release number of selected component (if applicable): scsi-target-utils-1.0.24-2.el6.x86_64 How reproducible: Need to include "--iscsi portal=x.x.x.x:3260" args to restrict socket binding on multi-homed system. Steps to Reproduce: 1. have a multi-homed system 2. require iscsi to only bind to one NIC 3. fail :-) Actual results: tgtd binds to 0.0.0.0:3260 by default. Expected results: tgtd binds only to a specific IP. Additional info: Adding support is trivial: ***BEGIN PATCH*** --- tgtd 2012-03-20 14:22:28.000000000 -0500 +++ tgtd.local 2013-03-15 16:24:57.298215576 -0500 @@ -31,7 +31,7 @@ [ -x /usr/sbin/$exec ] || exit 5 echo -n $"Starting $prog: " # Note /dev/null redirection to silence rdma not found messages - daemon $exec >/dev/null 2>&1 + daemon $exec ${TGTD_OPTIONS} >/dev/null 2>&1 retval=$? if [ $retval -ne 0 ] ; then failure ***END PATCH*** and since /etc/sysconfig/tgtd does not contain a TGTD_OPTIONS line, default behaviour remains unchanged. The workaround is obvious, but this needs to get into an errata pkg so I'm not customizing initscripts to support a fully-documented feature (see http://stgt.sourceforge.net/manpages/tgtd.8.html). Should be possible to include in errata since default behaviour does not change.
