Collecting data for problems with PowerHA SystemMirror on AIX

The following procedures are for data collection, not for problem diagnosis. Gathering this information before calling IBM support can aid in problem determination and save time resolving Problem Management Records (PMRs).

Using zsnap for PowerHA SystemMirror

Run # zsnap --HACMP

This zsnap command gathers PowerHA data and creates the testcase file in one step. If you already have a PMR number, see the example below.

  • -Data

    The zsnap command for PowerHA SystemMirror gathers the same information as snap at this time. The data include:

  • -Example

    See zsnap usage for all available options.

    # zsnap --HACMP --pmr 12345,123,123

    The example gathers the appropriate data and creates a testcase file with the IBM standard naming convention for quicker processing. You will be prompted to send the file to IBM using the FTP protocol. If you don't have a PMR number, omit the --pmr flag to build the testcase file.

    You can also run the zsnap command from the AIX SMIT menus.

Using snap for PowerHA SystemMirror

The snap command is the standard AIX tool that gathers data and stores that information in /tmp/ibmsupt/. The snap command does not gather the following additional PowerHA related information.

  • -Data

    See zsnap Data section above for the data collected by the snap command.

  • - Sample snap procedure for PowerHA

    See snap usage for all available options

    Follow these steps to gather the PowerHA data.

    1. Run the snap -r command to remove all previously gathered data on all of the nodes in the cluster.
    2. Gather the additional information and put it in /tmp/ibmsupt/testcase. You may need to recreate the testcase directory.
    3. Run # snap -e on just one node.
    4. Rename the testcase file to adhere to IBM testcase file naming conventions, and then send the file to IBM.
    5. For information on sending testcase information, read Sending Testcases Electronically.
