Error Handler Scsi Eh 0


If INTERMEDIATE or INTERMEDIATE-CONDITION MET status is not returned, the series of linked commands is terminated and the I/O process is ended. Once the initial timeout is reached (normally 30 seconds), the eh_deadline starts.  If the SCSI error handling doesn't complete before the eh_deadline timeout (if not defined as 0 by default) for This has to be cleaned.
