Remote System Control (rsctest)

The rsctest exercises the Remote System Control (RSC) feature, which is integrated on the Sun Enterprise 250 as well as the next-generation RSC 2.0 plug-in card introduced with the Sun Fire 280R line.

The RSC provides secure remote access for system monitoring, firmware updates, and failure recovery. The RSC communicates with the host through two internal serial lines, the I2C bus, and reset lines.

The RSC 1.0 hardware consists of the controller, flash, SEEPROM, 10MB Ethernet port, and an external console serial port.

The RSC 2.0 plug-in card hardware consists of the controller, flash, SEEPROM, 10MB Ethernet port, FRUSEEPROM, Time Of Day (TOD) device, internal PCMCIA modem card, and battery backup.

rsctest is not scalable.

rsctest Subtests

The rsctest will present different subtests and options based on which revision of the RSC hardware it is testing.

The subtests common to both RSC 1.0 and 2.0 include:

TABLE 44-1 Subtests for both RSC 1.0 and 2.0
Subtest	Description
Ethernet	Allows for internal loopback testing, on the Ethernet device with user specified data, size, and number of packets.Allows for external loopback testing with user-specified data, size, and number of packets. This requires a connection to a 10MB hub or switch for RSC 1.0, or a passive loopback connector for RSC 2.0.Allows for a ping to be sent to a specified host and checks the response.
Flash CRC	Performs a checksum test on the flash device.
SEEPROM CRC	Performs a checksum test on the SEEPROM device.
Serial	Allows internal loopback testing with user-specified data and size on the two internal serial ports. Allows for internal and/or external testing on the external `ttyu` port. The external test requires a passive loopback connector.

rsctest also presents the following subtests when running on the RSC 2.0 hardware:

TABLE 44-2 Subtests for RSC 2.0 Only
Subtest	Description
FRU SEEPROM CRC	Performs a checksum test on the SEEPROM device.
I2C	Tests the i2c bus connection between the host and the RSC.
TOD	Performs multiple reads to the TOD device and verifies that the time is incrementing.
Modem	Verifies that the modem is installed. Displays the manufacture information, in Verbose mode. Performs AT inquiry commands.

The subtests call test modlets that are written in the native Real Time Operating System (RTOS) that resides in the RSC firmware. The rsctest subtests execute the test modlets, passes parameters, and retrieves results from the RSC using a test protocol on the host to RSC internal serial lines.

rsctest Options

To reach the dialog box below, right-click on the test name in the System Map and select Test Parameter Options. If you do not see this test in the System Map, you might need to expand the collapsed groups, or your system may not include the device appropriate to this test. Refer to the SunVTS User's Guide for more details.

TABLE 44-3 `rsctest` Options
`rsctest` Options	Description
Enet test	Enables or disables RSC Ethernet testing.
Data Pattern Type	Selects Sequential, Random, or both types of data patterns.
Packet Size	Defines the size of each data packet to be sent for all tests.
Num Packets	Specifies the number of data packets to send in one test loop.
Target Host	Specifies the IP address of a host to use for the ping test.
Enet Test Type	Selects any or all Internal, External, or ping tests.
Flash test	Enables or disables the flash checksum test.
SEEPROM test	Enables or disables the SEEPROM checksum test.
FRU SEEPROM test	Enables or disables the FRU SEEPROM checksum test (RSC 2.0 only).
TOD test	Enables or disables the Time Of Day test.
I2C test	Enables or disables the I2C test (RSC 2.0 only).
Serial test	Enables or disables the RSC serial test.
Data Size	Defines the data size to be sent.
Loopback Type	Selects Internal, External, or both. External requires a loopback plug.
Data Pattern Type	Selects Sequential, Random, or both types of data patterns.
Serial Test Type	Selects serial ports to be tested, u to u, c to c, or d to d.
TTYU_Baud	Select a fixed baud rate or all baud rates for testing the ttyu port. The valid baud rates under TTYU_Baud are: ALL, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 76800, 115200. The default is 9600.
Modem Test	Used to Enable or Disable the RSC PCMCIA modem test (RSC 2.0 only).

rsctest Test Modes

rsctest supports Connection and Functional tests as described in the table below.

TABLE 44-4 `rsctest` Test Modes
Test Mode	Supported?	Description
Connection	Yes	Reports the status of the RSC.
Functional (Offline	Yes	Tests the RSC's Ethernet, flash, SEEPROM, and serial devices. All tests use internal modes as defaults. The `rsctest` will not run the serial test on ttyc if the console has been redirected to the RSC. The ttyu tests will not run if there is an open login on `ttyu` .
