driver:

What host type is the linux host configured as on the EVA (check in
command view under hosts) ?

Which version of the Controller software are you running ? (check
hardware - rack 1 - controller enclosure - controller a or b in command
view)
It is listed as software version.

Run hp_rescan on the host and send the output.

How many vdisks are presented to the host, what are their assigned luns
?

What does dmesg |grep sd return ?

I have a hunch but would like to confirm it with the data above.
