The vmemtest checks virtual memory; that is, it tests the combination of physical memory and the swap partitions of the disk(s).
This test may not stop immediately after being disabled.
This test uses the Solaris valloc (page aligned) system call to allocate, write, read, and compare virtual memory. These operations normally cause heavy paging activity on the system and simulates a stressful environment for the operating system. This test also detects ECC parity errors, memory read errors, addressing problems, and displays the corresponding virtual memory addresses on failure.
Running this test places a significant burden on the operating system, since it uses the majority of swap space available for testing. You should use the vmemtest swap space reserve option when non-SunVTS test processes are started after SunVTS testing has started. See "Swap Space Requirements" in the SunVTS User's Guide for a complete discussion of swap space requirements.
This test is only available in the Functional test mode. In this mode the, vmemtest writes a pattern to an amount of virtual memory specified by the user. Then the data is read back and compared. If there is a miscompare, the data is read again and compared. Whenever there is a miscompare, the virtual address is reported. When there is a miscompare on recomparison, an attempt is made to convert the virtual address to the physical address if the SunVTS diagnostic driver is installed.

Table 42-2 vmemtest Command Line Syntax
Argument |
Explanation |
---|---|
mode=type |
Specifies which mode of the vmemtest you want to run; you can choose between page mode, which tells the write/read memory test to proceed one system memory page at a time, and regular, which valloc's the entire assigned memory which is read and compared, one long word at a time. |
reserve=number |
Specifies the amount of Mbytes of virtual memory to reserve in addition to the default amount. |
amount=number |
Specifies the number of Mbytes of memory to be tested instead of the default amount. |
bdinfo=number |
Provides the board number information for all the CPU/memory boards in the system. For example, if board 0 and board 5 have memory, then the bdinfo=33 (2**5+2**0). |
cerr=number |
Specifies the maximum number of contiguous errors to be dumped when a memory error occurs. |
64-bit tests are located in the sparcv9 subdirectory: /opt/SUNWvts/bin/sparcv9/testname. If a test is not present in this directory, then it may only be available as a 32-bit test. For more information refer to "32-Bit and 64-Bit Tests".
