http://blogs.msdn.com/san/archive/2008/07/28/microsoft-iscsi-software-initiator-location-guide.aspx

      2. Pre-configured iSCSI target. You will first need to create a LUN on your iSCSI target. A list of supported targets   is here:  http://blogs.msdn.com/san/archive/2008/08/04/logo-listings-for-enterprise-storage-arrays.aspx

SET ipaddress=%1

echo "Trying to add target %1 for discovery"

iscsicli QAddTargetPortal %ipaddress%

REM – Find out the number of Targets discovered for the portal address

SET _count=0

FOR /F "usebackq skip=1" %%G IN (`iscsicli ListTargets`) DO (

SET _cmp=%%G

SET _result=!_Cmp:~0,4!

REM - Get a valid IQN Name.

IF !_RESULT!==iqn. (

set TargetName=!_cmp!

SET /a _count = _count + 1

)

)

REM - Check if there is only one target.
