    Dear,

    actually we have an infrastructure based upon XenServer 7.0
    With an external storage (SAN), that mount the SR with (ISCSI).

    Some times, we come with network problems.
    With that problems, the VMs lost the connection with the SANs, and the filesystem goes to
    read only, very quickly.

    Multipath is not available at the moment. So we want to rise up the IO timeout so
    that a momentary disconnection of SAN does not cause an immediate readonly disk change.

    Can you describe how to do that, on a VMs under XEN?

    Thank you.
