System Test Monitor,
Continued
The following tests are included:
Inquiries test
Performs inquiries to find out which devices are connected to
the SCSI bus.
Size Bus test
Spins up all the hard disk drives, ensures that the drives are
ready (if not in customer mode), forces disk block sizes to 600
bytes, and obtains the capacity of the drives. This test also
verifies that removable media are write protected; that the
key pattern is present on removable media in Digital Services
mode; and that VMS boot block is present on the hard disk
drives when in manufacturing mode.
Data Transfer test
Verifies SCSI bus communication between the controller and
available peripherals. It also verifies the data path of the
controller to the memory.
Device test
Verifies the peripheral devices attached to the SCSI bus, and
the DMA data path. Interrupts are enabled.
