TABLE 10-3 bsctest Command-Line Syntax




device_name is the device to be tested, for example, bsc


testlist is the list of subtests, for example: BSCSelfTests, PSU, Fan, Temp, ToD, OBP, EEPROM, LED

Note - 64-bit tests are located in the sparcv9 subdirectory:
/opt/SUNWvts/bin/sparcv9/testname, or the relative path to which you installed SunVTS. If the test is not present in this directory, then it may only be available as a 32-bit test. For more information refer to the "32-Bit and 64-Bit Tests" section of the SunVTS 5.1 Test Reference Manual (816-5145-10).
