Hello gents just to really undesrstand my issue I want to know if the connector is playing any role after the Luns are connected like in the transfer of data?
Secondly I did some researchs in the Internet where people are saying to deactivate MPIO . how do you do that on the ISCSI connector? and what are the consequences? if it were activated before

Hi
Yes off course, you can see the connector as a driver like IDE or SATA, without it functioning the OS has no clue there is a SAN nor does it understand Some iscsi commands.
Disabling MPIO is not something i can advise, you can do it in two ways. Delete the feature or delete the disks in MPIO properties.

MPIO is for sharing same volume with multiple machines, if the volume is not accessing from any other server then you can disable it..
from Iscsi initiator you can disable it ...
as well you can disable multi path from Equallogic volume properties there some where you'll find the check box...
all the best
