Controller diagnostic data collected

A controller was not able to process host I/O requests for an extended period of time (perhaps several minutes). This caused diagnostic data to be collected for both controllers and this problem to be reported. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

Important:
  • Diagnostic data can be used by your Technical Support Representative to diagnose potential problems.

  • You can resolve this problem in two ways:

    • Save the diagnostic data to a file.

    • Reset the diagnostic data status.

Recovery Steps

  1. Open either the Script Editor from the Enterprise Management Window (EMW), or the Command Line Interface (CLI).

    Note: The commands in this procedure are formatted as they are used in the CLI. Refer to the EMW online help for assistance with formatting these commands for the Script Editor.
  2. Perform one of the following steps:

    • If you want to save the diagnostic data, go to step 3.

    • If you do NOT want to save the diagnostic data, go to step 5.

  3. Execute the following command:

    save storageArray diagnosticData file="filename";

    Where filename is the location and name of the file that will be saved. The file will be formatted as a .zip file.

  4. Perform one of the following steps:

    If... Then...
    No error was returned Go to step 6.
    An error was returned
    • If the error message indicates that there was a problem saving the data, wait 2 minutes and then restart step 3.

    • If the error message indicates that there was a problem resetting the data, wait 2 minutes and then go to step 5.

  5. Execute the following command:

    reset storageArray diagnosticData;

    If an An error was returned, wait 2 minutes and then execute the command again. The controllers may need additional time to update status. You may also get an error if the diagnostic data status has already been reset.
