SCSI Commands
Quantum DLT 8000 Tape System
5-39
LOG SELECT Command (4Ch) (continued)
5.7.1 Log Detection Summary in LOG SELECT Command Descriptor Block
The following conditions constitute errors that are detected by the drive in relation to
the CDB. The request sense data is set to ILLEGAL REQUEST, INVALID FIELD IN
CDB.
The conditions that constitute errors are:
•
PCR bit is set to 1 and parameter list is not set to 0.
•
SP bit is set to 1
•
A parameter list length that would cause a parameter within a valid page to be
truncated or otherwise incompletely initialized.
5.7.2
Operation of LOG SELECT
The LOG SELECT command allows the initiator to modify and initialize parameters
within the logs supported by the tape drive.
There are two ways to initialize the log parameters.
1.
Set the PCR bit in the LOG SELECT CDB; this clears all parameters.
2.
Specify the log page and parameter values as the log parameters to clear individual
pages. The following pages can be cleared using this method:
Page Code
Page Description
02h
Write Error Counter Page
03h
Read Error Counter Page
32h
Compression Ratio Page
If multiple pages are sent during the DATA OUT phase, they must be sent in ascending
order according to page code. Otherwise, the command terminates with a CHECK
CONDITION status, sense key set to ILLEGAL REQUEST, and additional sense code
set to INVALID FIELD IN PARAMETER LIST. The same status is returned if an
unsupported Page Code appears in any header or if the specified page cannot be cleared.
