Format Command Failure Degraded Mode Note: This table assumes FDD (Mode Page 0) is set to zero. 11.1.9 Command processing while reserved A logical unit is reserved after successful execution of the RESERVE command. Each time a RESERVE command is executed successfully, the Target records the SCSI ID of the Initiator that made the reservation and the SCSI ID of the Initiator that is to receive the reservation. This information is needed to determine whether subsequent commands should be permitted or if the RESERVATION CONFLICT Status should be reported. The Initiator to receive the reservation may be either the same or a different Initiator (third-party reservation). If the logical unit is reserved when a new command is received, the Target examines the command opcode and the SCSI ID of the issuing Initiator to determine whether a RESERVATION CONFLICT Status should be returned based on the following rules: 1. If the issuing Initiator is the one that made the reservation and also the one to receive the reservation, all commands are permitted. 2. If the issuing Initiator is neither the one that made the reservation nor the one that receives the reservation, ! A REQUEST SENSE, INQUIRY, REPORT LUNS, LOG SENSE, READ CAPACITY, REPORT DEVICE IDENTIFIER or START STOP UNIT with START bit is permitted. ! A RELEASE command is permitted but is ignored ! Any other command results in a RESERVATION CONFLICT Status Ultrastar 146Z10 hard disk drive specifications 203

11.1.9 Command processing while reserved
A logical unit is reserved after successful execution of the RESERVE command. Each time a RESERVE
command is executed successfully, the Target records the SCSI ID of the Initiator that made the reser-
vation and the SCSI ID of the Initiator that is to receive the reservation. This information is needed to
determine whether subsequent commands should be permitted or if the RESERVATION CONFLICT
Status should be reported.
The Initiator to receive the reservation may be either the same or a different
Initiator (third-party reservation).
If the logical unit is reserved when a new command is received, the Target examines the command
opcode and the SCSI ID of the issuing Initiator to determine whether a RESERVATION CONFLICT Status
should be returned based on the following rules:
1.
If the issuing Initiator is the one that made the reservation and also the one to receive the reserva-
tion, all commands are permitted.
2.
If the issuing Initiator is neither the one that made the reservation nor the one that receives the
reservation,

A REQUEST SENSE, INQUIRY, REPORT LUNS, LOG SENSE, READ CAPACITY, REPORT
DEVICE IDENTIFIER or START STOP UNIT with START bit is permitted.
!
A RELEASE command is permitted but is ignored
