Sun Fire 880 FC-AL Disk Backplane Test (dpmtest)

dpmtest tests the Sun Fire trademark 880 FC-AL disk backplane. dpmtest verifies the operation of the embedded SES controllers and the disk enclosure system of the Sun Fire 880 workgroup server.

No special hardware is required to run the dpmtest test.

dpmtest 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.

FIGURE 13-1 dpmtest Test Parameter Options Dialog Box

TABLE 13-1 `dpmtest` Test Options
Option	Description
Test Path	Default: Test runs using the interface through which the test was registered. If the device tested is an SES device, then the `dpmtest` tests the device over the fiber channel interface. If the device is registered as an SSC100 device, then it tests over the I2C interface. Both: If selected, the test runs the same tests to this device over both the Fiber channel interface and the I2C interface. Note: This option will be grayed out if both paths are not available.
Loopback Test	When enabled, the subtest will cause the SES device to loop a packet around the fiber bus with varying data patterns. The device reads the packet after the packet is received, and verifies that the data payload is correct. Note: This test grays out if the SSC100 does not have access to the fiber bus.
Firmware Test	When enabled, this subtest runs the system friendly embedded firmware tests on the SES/SSC100 device.

dpmtest Test Modes

TABLE 13-2 `dpmtest` Test Modes
Test Mode	Supported?	Description
Connection	Yes	The test opens the device, extracts information about the device (firmware revision, drives installed, temperatures, etc) and displays the information for the user. Once the test is run, the device closes and the test exits.
Functional (Offline)	Yes	The test opens the device and runs the selected tests against the device. When fully run, the test closes and reports the results.

dpmtest Command-Line Syntax

/opt/SUNWvts/bin/dpmtest standard_arguments -0 dev= [device name] , path= [Default|Both] ,lb= [Enable|Disable] ,fwtest= [Enable|Disable]

TABLE 13-3 `dpmtest` Command-Line Syntax
Argument	Description
`-0 dev=` [device name]	[device name] is the path name of the device being tested.
`path=` [Default\|Both]	Default: Test runs using the interface through which the test was registered. If the device tested is an SES device, then the `dpmtest` tests the device over fiber channel interface. If the device is registered as an SSC100 device, then it tests over the I2C interface. Both: If selected, the test runs the same tests to this device over both the Fiber channel interface and the I2C interface. Note: This option will be grayed out if both paths are not available.
`lb=` [Enable\|Disable]	When enabled, the subtest will cause the SES device to loop a packet around the fiber bus with varying data patterns. The device reads the packet after the packet is received, and verifies that the data payload is correct. Note: This test will be grayed out in the case where the SSC100 does not have access to the fiber bus.
`fwtest=` [Enable\|Disable]	When enabled, this subtest runs the system friendly embedded firmware tests on the SES/SSC100 device.
