136.0. "DECRAM$SETSHAD fails with ILLIOFUNC" by CSC32::HENNING (A rose with no thorns) Wed Feb 12 1997 11:50

    Morning!
    
    I've installed DECram V2.2B on a standalone system running OpenVMS VAX
    V6.1, in order to perform some tests that will involve volume shadowing
    of the DECram devices.  I'm unable to use DECRAM$SETSHAD to redefine
    the ramdisks' device types, because DECRAM$SETSHAD.EXE fails with 
    
      %SYSTEM-F-ILLIOFUNC, illegal I/O function code
    
    The DECram devices appear to be local, as the attached shows.  Is there
    a problem with SETSHAD, or (more likely) am I missing something here?
    
    Thanks in advance,
    Mary

    $ @sys$manager:decram$setshad $1$mda1002:

    Any replies?
    
    The only report of the ILLIOFUNC occurred because local DECram devices
    weren't used (see attached article).  I created my disks on a
    standalone system, following steps outlined in the users manual.  What
    else can cause this error?

SYMPTOM:

Executing either of the two command procedures:

     @SYS$MANAGER:DECRAM$SETSHAD decram_device_name
     @SYS$MANAGER:DECRAM$SETRAM decram_device_name

returns the following error:

     %SYSTEM-F-ILLIOFUNC, illegal I/O function code


SOLUTION:

These command procedures can ONLY be run on local DECram
devices.  They are not intended to be executed on MSCP
served DECram devices.

For further explanation of what these two command procedures
do, please see another article entitled:

Guess not !

    Yes.  DECram engineering does read this conference.
    
    However, DECram engineering is one man.
