SCSI Sense Data

When something wrong happens on your SCSI network (FC, iSCSI, infiniband, FCoE, etc…), error messages rise in ESXi logs.

When a SCSI target device returns a check condition in response to a command, the initiator usually then issues a SCSI Request Sense command. This process is part of a SCSI protocol called Contingent Allegiance Condition. The target will respond to the Request Sense command with a set of SCSI sense data which includes three fields giving increasing levels of detail about the error
