In /etc/tgt/targets.conf
wildcard (172.16.2.*
) not work with initiator-address. I'm preparing for Red Hat High Availability Clustering exam (EX436).
The student workbook says:
With
tgtadm
command, You are allowed to use wildcards like 172.16.X.* in an--initiator-address
option if you want.
But this is configuration in targets.conf
is not working with a wildcard:
# cat /etc/redhat-release
CentOS release 6.6 (Final)
# rpmquery scsi-target-utils
scsi-target-utils-1.0.24-16.el6.x86_64
# cat /etc/tgt/targets.conf
....
<target iqn.2015-09.rhel6.storage1>
backing-store /dev/mapper/vg_rhel6-clustorage1
vendor_id ex436prep
initiator-address 172.16.2.*
</target>
# tgt-admin -s

But when I set initiator-address
to the initiator’s IP address (172.16.2.10
) in targets.conf
, everything works as expected:
# cat /etc/tgt/targets.conf
...
<target iqn.2015-09.rhel6.storage1>
backing-store /dev/mapper/vg_rhel6-clustorage1
vendor_id ex436prep
