James,
Do you have a sample. I will only be using a limited number of iscsi targets which will be well defined for our organization.

A workaround may be to write udev rules to give your iSCSI devices
persistent alternate names. If you are connecting multiple targets then
the device names would change if the order they connected changed. I
have set my system up to create a /dev/iscsi/... device which I
reference instead of the /dev/sd... one.
