As far as I remember, that didn't work for us. We've always ran 4.0.x.y 
linux-iscsi, and took us a bit of time to figure out what was going on.

Not yet, with the amount of problems we have had with linux-iscsi, and finally 
arrived at a semi-stable setup, we decided we'll wait a bit before 
experimenting with another implementation of iscsi driver.

However, on a side note, we are trying to implement an environment where we 
use linux software raid 1 across multiple iscsi targets. It tooks us a bit of 
figuring out how to properly do it with the linux-iscsi, and we're still not 
happy with the results. 

The question would be, does anybody else use raid1 across iscsi targets, and 
what are your comments regarding the setup? Of course the basic functionality 
we are looking for is ability of the driver to detect failed devices and 
report it after X amount of time to the scsi layer. The second and also very 
important issue is being able to re-attach an iscsi target without stopping 
the entire iscsi interface on the initiator. In a scenario where iscsi 
targets are available to the initiator, then raid1 is laid over them, then 
lvm, then a filesystem, and multiple iscsi targets are attached to the 
initiator, any interruption in the existing connections is fatal. 

I guess if anybody has any comments/thoughts on this subject, please share 
them with me. 

thank you,
