status_key Error Codes

SBCSCSI/D1 D-3

SS_RSVCON (0x18)

This is the SCSI status of RESERVATION CONFLICT. This status is returned

whenever an initiator attempts to access a logical unit that is reserved

exclusively for another SCSI initiator.

This error indicates that in a multiple initiator system another initiator has

locked a target device. The simplest recovery attempt is to retry this command

at a later time in hopes that the device has since become released. Recovery

beyond this measure would require communication with the other initiator

through some user defined protocol.

SS_CMDTERM (0x22)

This is the SCSI status of COMMAND TERMINATED. This status is returned

whenever the target terminates the current I/O process after receiving a

terminate I/O process message. This is the expected status posted to the user

in response to initiating this message.

SS_QFULL (0x28)

This is the SCSI status of QUEUE FULL. This status is implemented if tagged

queuing is implemented. This status is returned when a simple queue tag,

ordered queue tag, or head of queue tag message is received and the

command queue on the target device is full.

This status indicates that the Firmware is configured for a Q_DEPTH greater

than that supported by the target device. The user may simply wait until

outstanding commands to the Firmware are returned before resending this

command; however, a more robust solution would be to reconfigure the target

device Q_DEPTH to a smaller value using the Firmware CONFIG command.
