By default the LUN number is 0, when you insert in the dhcp server
iscsi:ServerAddress.x.com::::iqn.2009-11.com.x:test
The problem is that TGT is by default assigning 0 to the controller of the iSCSI drive, and the LUN number for the device itself is 1.
So you must assign the value 1 to the definition.
iscsi:ServerAddress.x.com:::1:iqn.2009-11.com.x:test
… if you don’t assign it, you will get error “ 0x1d704039 ", or PXENV_STATUS_TFTP_CANNOT_READ_FROM_CONNECTION.

BTW, here is my configs…
