Resolution
Restart tgtd on the VM's hypervisor. This can be done with 'service tgtd restart'.
If tgtd is stuck, you will need to kill the old processes and then restart it.
[root@sjhypervisor1 ~]# ps aux | grep tgtd
root 13240 0.0 0.0 103296 836 pts/10 S+ 12:10 0:00 grep tgtd
root 28097 0.0 0.0 54836 1152 ? Ss 02:10 0:03 tgtd
root 28098 0.0 0.0 19916 424 ? S 02:10 0:01 tgtd
[root@sjhypervisor1 ~]# kill -9 28097 28098
[root@sjhypervisor1 ~]# /etc/init.d/tgtd restart
Stopping SCSI target daemon: not running [FAILED]
Starting SCSI target daemon: [ OK ]
[root@sjhypervisor1 ~]#
Make sure to use "restart" and not "start". Restart will clean up the old stuff from the previous running tgtd processes.
Cause
The backup server needs to log in to the iscsi targets on that HV. These targets are temporarily created for the backups.
