Hmm, if you use two files, why can't you do like:
<target iqn.2010-03.com.cluster1:01>
<backing-store /gpfs/file1>
vendor_id cluster1
product_id target1
scsi_id cluster1_target1_lun1
lun 1
</backing-store>
</target>
<target iqn.2010-03.com.cluster1:01>
redirect-address 10.0.1.51
redirect-port 860
redirect-reason Temporary
</target>
I might be wrong since I don't know about tgt-admin.
btw,
<target iqn.2010-03.com.cluster1:01>
<redirect>
address 10.0.1.51
port 860
reason Temporary
</redirect>
</target>
It looks prettier?
