HSI/S Boards Test (sunlink)

This test verifies the functionality of the SBus HSI boards. sunlink tests the HDCL and SDLC protocol of SBus HSI boards. sunlink downloads the DCP microcode, initializes the selected channel, and configures the selected channel to the protocol being tested.

Next, sunlink opens a datagram socket and tries to modify the socket to accept ioctl communications with the driver, and receive synchronous mode information from it.

sunlink then opens the ports, linking the upper and lower layers with ioctl calls. After initialization, this test checks for activity before attempting to send or receive data. An error message is returned if activity is detected; otherwise the transmit buffer is filled with random data. Random data is used by default; other patterns may be specified. The data is then transmitted. If the transmission succeeds, sunlink then receives the returned data and verifies that it is identical to what was sent.

Finally, statistics about the send and receive are gathered from the socket.

A full sunlink test takes approximately 8 minutes per port. sunlink does a brief check of the board ports before the actual test begins. If the port is bad, the test immediately aborts and returns an error message.

Note - This test will not pass unless you install the correct loopback connectors or port to port cables on the ports you are testing. The ports specified for test in the option menu must have loopback connectors attached. See Appendix A for loopback connector part numbers and wiring instructions.

• Clock Source lets you select either the on-board clock or an external clock for use when using sunlink. To use the external clock option, the transmit, receive, and clock data lines must be physically loopbacked.

• Internal Loopback enables or disables internal loopback tests. Internal Loopback is only needed when the Loopback setting is not port-to-port, and the clock source is on-board.
• Loopback specifies the loopback type: simple single external port loopback, multiple external port loopback, and port-to-port external loopback.

sunlink Command Line Syntax

/opt/SUNWvts/bin/sunlink standard_arguments -o
dev=device_name,P=port#, p=data_pattern,I, C=B/E

Argument	Explanation
dev=device_name	Specifies the device to be tested. hih0 HDLC and SDLC protocols
P=ports	Specifies the port number to be tested.
p=data_pattern	Specifies the data_pattern as one of the following: c..Character (0x55) i..Incrementing d..Decrementing r..Random (default)
I	Enables internal loopback for HSI/S (external).
c=clocksource	Specifies the clock source value as one of the following: B..On-board clock source E..External clock source

The following is a typical command line syntax for testing an HSI/S Sbus card:

# /opt/SUNWvts/bin/sunlink -o dev+hih0,P=0_to_1+2_to_3

Typing this at the command line tests the internal loopback for port 0.
