    ESX4.1 and iSCSI Enterprise Target - Writes failing

    raining Novice

      I am using ESX4.1 with Fiber Channel Backend storage. I also have a Virtual Appliance exporting an iSCSI Enterprise Target (IET) to the server. I initiated a copy of a vmdk file from the Fiber Channel datastore to the datastore created on the IET LUN and get only 5 IOPS. When I look at the vmkernel, I see plenty of Abort messages as shown below:

      Eventually, the iSCSI connection was marked on ONLINE, but writes kept failing, until eventually the connection was marked as OFFLINE once again as seen below:
