Example message

"Lost access to volume 496befed-1c79c817-6beb-001ec9b60619 (san-lun-100) due to connectivity issues. Recovery attempt is in progress and outcome will be reported shortly."

VMware states this is due to the heartbeat not being received for a period of 16 seconds.

This only happens with FC volumes iscsi are ok, any help would be appreciated. I looked at the tests.log but it means nothing to me
