Unfortunately this function is not available. There are applications that provide additional functions that will assist on this and allow multiple systems to access the same Target
by using a special SAN file system.

SAN File System programs. Examples are listed below:

SAN file system solutions are very expensive. The easiest way to share
the data on iSCSI Target is to create network share and get clients to
connect to the network share and not directly to the target.
