DRIVE COMMAND SETMODE SELECT (15H)The SCSI sense information bytes point to the last block within the read extent that required any of therecovery described previously. The ACCESS EVENT LOG command can be used to determine the natureof the recovery.For write commands, a recovered error will be posted when a relocation is required in the write extent. TheSCSI sense information bytes will point to the last block relocated in the write extent. In the absence of arelocation in the write extent, a Spares Full Warning, Sense Key 01, ASC 32 and ASCQ 00, may be postedto the host. This will occur if the number of relocation sectors left on the side of media that is being writtento is 100 or less.Refer to the REQUEST SENSE command description for the relevant Sense Key and Error Codedefinitions.DTEIf the Disable Transfer on Error (DTE) bit is set, the LaserDrive will terminate the data phase when arecovered error is detected. If the DTE bit is not set, the LaserDrive will not terminate the data phase whena recovered error is detected. The PER bit must be set if the DTE bit is set.Read Retry CountThe Read Retry Count fields specify the number of times that the LaserDrive shall attempt its recoveryalgorithm during read operations. This value is 16 and cannot be modified; however, values of 4 and 8 willnot be rejected.NOTEIf an invalid mode for the error recovery combination is sent by theInitiator, the Target shall return CHECK CONDITION status with theSense Key set to ILLEGAL REQUEST and the Additional Sense Codeset to Invalid Field In Parameter List.DEVICE DISCONNECT/RECONNECT PARAMETERSThis page specifies the parameters that control the LaserDrive's SCSI bus usage during data transferoperations.Disconnect/Reconnect Parameters Page (02H)BITBYTE7 6 5 4 3 2 1 000 Reserved Page Code (02H)01 Parameter Length (0AH)02 Reserved03 Reserved04 Reserved05 Reserved06 Reserved07 Reserved08 Reserved09 Reserved10 Maximum Burst Length (MSB)11 Maximum Burst Length (LSB)97653978 HPage 71
