Windows client dump capability

This topic describes how to create system dumps for SAN File System clients using the Windows® 2000 and Windows 2003 operating systems.

You can configure the operating system to generate a dump file if the SAN File System client on the Windows operating system terminates abnormally. By default, the file is C:\WINNT\memory.dmp. You can also configure where the file is saved.

In cases where the SAN File System client hangs, you can force the creation of a dump file. However, you must have previously configured the system to allow the creation of a dump file by:
  • Making sure that the system is configured to generate a dump file. To verify the settings, click Start > Control Panel > System > Advanced > Startup and Recovery > System Failure.
  • Using the registry editor (regedit) to modify the following registry setting:
    Hive:
    HKEY_LOCAL_MACHINE
    Key:
    System\CurrentControlSet\Services\i8042prt\Parameters
    Name:
    CrashOnCtrlScroll
    Data Type:
    REG_DWORD
    Value:
    1
    Note: A value of 1 enables the feature.

    To create a dump file, press and hold the right Ctrl key while pressing ScrLk twice from the keyboard. The dump file is generated the next time you restart the machine.
