Reservation Conflict
The COMMAND STATUS description is as follows:
Good - Indicates the WREN IV has successfully completed execution of the command.
Check Condition - Any error, exception, or abnormal condition that causes sense data to be set will cause a
Check Condition Status. The Request Sense command should be issued in response to
a Check Condition status, to determine the nature of the condition.
Busy - Indicates the WREN IV is busy. This status will be sent whenever a WREN IV is unable to accept a
command from an Initiator.
Reservation Conflict - This status will be returned whenever a SCSI device attempts to access a logical unit
that is already reserved for that type of access to another SCSI device.
