Can you help me with some more information to solve the problems? Is this SCSI command time-out something that happened on the target server with the storage, my storage is having a hard time with high latencies, but I am not having any hardware warnings/errors. Or is this related to the iSCSI client servers as well? I am using open-iscsi as client: http://paste.debian.net/108898/ These are my node records and settings, is there a setting I should try to change or optimise for tgtd?
