Hi Siva,

What seems to be the problem at hand? What kind of range of values for 
TargetPort do you propose?
TARGET_PORT_MIN/MAX_NUM refer to a range of values (0-65535) that be set 
in TargetPort field in iSCSI HII. 3260 is a default TCP port for iSCSI.
I see nothing wrong with that.

Thanks,
Maciej
