DOSD (Dump Off System Disk) allows you to write the system dump
    file to a device other than the system disk. For SDA CLUE to
    be able to correctly find the dump file to be analyzed after a
    system crash, you need to perform the following steps:

    1. Modify the command procedure SYS$MANAGER:SYCONFIG.COM to
       add the system logical name CLUE$DOSD_DEVICE to point to
       the device where the dump file resides. You need to supply
       only the physical or logical device name without a file
       specification.

    2. Modify the command procedure SYS$MANAGER:SYCONFIG.COM to mount
       systemwide the device where the dump file resides. Otherwise,
       SDA CLUE cannot access and analyze the dump file.

    In the following example, the dump file has been placed on
    device $3$DUA25, which has the label DMP$DEV. You need to add
    the following commands to SYS$MANAGER:SYCONFIG.COM:

    $ MOUNT/SYSTEM/NOASSIST $3$DUA25: DMP$DEV DMP$DEV
    $ DEFINE/SYSTEM CLUE$DOSD_DEVICE DMP$DEV
