hardware operation. For this test to be meaningful, the machine under test

must be attached to a network with at least one other system on the

network.

Parallel Test

The Parallel test verifies the functionality of the IEEE 1284 parallel port

device by performing an internal loopback test that transfers a known data

pattern.

"  Serial Test

The Serial test checks the system's on-board serial ports (zs[0,1], zsh[0,1],

se[0,1], and se_hdlc[0,1]), as well as multi-terminal interface (ALM2) boards 

(

mcp[0-3]

). Data is written and read in asynchronous and synchronous

modes utilizing various internal loopback paths.

SPARCstorage" Array Controller Test

This test checks the functionality of the controller board on the

SPARCstorage" array by checking the state of the array's battery and fan

modules. It also invokes SCSI read buffer commands of various sizes to the

array's NVRAM, verifying the host and array Fibre Channel hardware, the

array resident management software, and the hardware component

interaction on the array controller card.

"

Tape Test

This test verifies that the tape drive is connected, the tape media is loaded,

and the drive type can be determined.
