The SET HOST/DUP command creates a virtual terminal connection and
executes a utility or diagnostic program on a storage controller that
uses the Diagnostic and Utilities Protocol (DUP) Standard Dialogue.
Once the connection is established, operations are performed under the
control of the utility or diagnostic program.
When the utility or diagnostic program terminates, control is returned
to the local system.
To abort or prematurely terminate the connection and return control to
the local system, press Ctrl/\.
Further information regarding the operation of the utility and
diagnostic programs available on a particular controller may be
obtained from the appropriate documentation set for that controller.
Preparing for Use
To use the SET HOST/DUP facility, you must first install FYDRIVER, the
DUP class driver. To load FYDRIVER, add the following commands to the
SYSTARTUP.COM command procedure in the SYS$MANAGER directory.
On Alpha and Integrity servers, specify the following commands:
$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> IO CONNECT FYA0/NOADAPTER/DRIVER=SYS$FYDRIVER
This operation requires CMKRNL (change mode to kernel) privilege.
