CAM-StatusValues
detect completion of the request. An AWAITIO[X] procedure call must be used to
detect completion of the request and transfer of the data back to the user buffer.
These CAM-status values are added or changed as follows:
•
CAM-status value 1B is reserved under the current CAM specification. This CAM
status has the meaning of Software Error and indicates either that the IOP
encountered a processing error or that one of the software subsystems the IOP
interacts with reported an unrecoverable error.
•
CAM-status values 1C through 3F are not returned by the IOP and need not be
checked by the application.
Table 3-8 lists the hexadecimal CAM-status values supported by the Open SCSI IOP
and gives the description or meaning for each. This table includes a subset of the
CAM-status values listed in the ANSI X3T9.2 792D (1994) CAM specification.
