[Users] Storage domain issue iSCSI

[Yeela Kaplan]

Just a clarification, the UUID of the pool is f1b40ecc-b6a9-44e7-92cb-0fdf445e3175
and the UUID of the msd it is looking for is 68d8b0e2-c348-4cfe-a896-08c62d491dfb (according to the logs you sent me).
The problem really is in the msd version (Thanks Shu) but I need more details in order to solve the issue, 
can you also attach the engine logs?
thanks.
