4.10 MODE SENSE (6) / (10) Command (1Ah / 5Ah)

The MODE SENSE command allows the SDLT tape drive to report its media type and current—or

changeable—configuration parameters to the host. It is a complementary command to MODE

SELECT.

The CDB for the 6-byte MODE SENSE (1Ah) command is shown below. An illustration of the CDB

for the 10-byte MODE SENSE (5Ah) command follows on the next page.

NOTE: 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 not changeable. In such cases, the drive

does not change any parameters as a result of the command.
