to an initiator that specifies an incorrect Buffer ID, Mode, Length or Buffer Offset. The Mode is

always Data (0x2), the Buffer ID is always 0 and the Buffer Offset is always 0.

Exhibit 4.1-2 The SCSI command process: reserve the Diamond-VT, send the command, release the Diamond-VT.

Initiator/Host

 

Diamond-VT

 

 

 

Goal: reserve the Diamond-VT for an in-band CLI command

 

 

SCSI cdb: Reserve LUN 0

=>

 

 

<=

SCSI success

 

 

 

Goal: retrieve the Diamond-VT temperature via in-band CLI

 

 

1. Issue the command:

 

 

SCSI cdb: WriteBuffer LUN 0, bid=’AA’, “get Temperature\n”

=>

places “Temperature=28C\n\r” into

 

 

the read-data buffer

 

<=

SCSI success

2. Retrieve the results:

 

 

SCSI cdb: ReadBuffer LUN 0, bid=’AA’

=>

 

 

<=

Returns “Temperature=28C\n\r” from

 

 

the read-data buffer

 

<=

SCSI success

 

 

 

Goal: release the Diamond-VT for other in-band users

 

 

SCSI cdb: Release LUN 0

=>

 

 

<=

SCSI success
