Description
Parameters Savable. For MODE SELECT, this bit must be 0.
This field indicates the number bytes in the page. However, the value
does not include bytes 0 and 1. The length is returned in MODE
SENSE commands and must subsequently be set to the same value
when performing MODE SELECT. If the page length does not match
that expected by the drive, a CHECK CONDITION status is returned,
sense key set to ILLEGAL REQUEST.
The drive returns a CHECK CONDITION status with sense key set to
ILLEGAL REQUEST if it receives an unsupported Page Code or a Page
field with values not supported or changeable. In such cases, no
parameters are changed as a result of the command.
Performance bit. Not supported.; always = 0.
Disable Information Exception Operations. If = 0, the reporting
method specified by the contents of MRIE is selected. When this bit
= 1, all information exception operations are disabled and the
contents of the MRIE field are ignored. When in this mode, the
TapeAlert Log page is polled by the software. To enable CHECK
CONDITION mode, DExcpt should = 0. Default setting = 1.
Test Bit. Not supported.
Error Log. Not supported
