SCSI Commands

∙When a WRITE 0 FILEMARKS command is issued.

∙When data has been in the cache longer than the maximum time specified by the value of the Mode Parameter “Write Delay Time” (the default is 30 seconds).

∙When a non-write type media access command is received (for example,

SPACE, READ, UNLOAD, LOCATE, ERASE).

5.2SCSI COMMAND DESCRIPTIONS

The SCSI commands are presented in alphabetical order. Each command starts on a new, odd-numbered page. Because information about a particular command may span multiple pages, the command name is repeated, in italics, at the top of every page that concerns that command. Blank pages in the chapter can be used for note-taking.

The SCSI command descriptions that make up the rest of Chapter 5 contain detailed information about each command supported by the Quantum DLT 7000 system tape drive. Fields common to many of the SCSI commands are supported as follows:

Name of Field:

How Field is Supported in SCSI Commands:

 

 

Logical Unit Number

LUN for tape drive is 0.

Reserved

Reserved bits, fields, bytes, and code values are set aside for

 

future standardization and must be set to 0. If the drive

 

receives a command that contains non-zero bits in a

 

reserved field or a reserved code value, the command is

 

terminated with a CHECK CONDITION status and the sense

 

key is set to ILLEGAL REQUEST.

RelAdr

Relative Address. Unused; contents should be 0.

 

 

Explanations for those common fields are not repeated for every command in which they appear.
