DECnet between OpenVMS VAX and OpenVMS Alpha?

» close window

The Question is:

 
I am trying to make a connection from a Alpha 400 workstation runing VMS 7.1
to VAX runing 5.3 via Decnet.   I have named my Alpha a node predifined with
NCP on the VAX.  I tried defining the VAX node on the Alpha in NCP and it
will not take.  How can I g
et the Alpha to see the VAX?  What am I doing wrong?
 


The Answer is :

 
  Please contact the customer support center.
 
  Expect to be asked for the specific commands used, whether or not
  you are using DECnet-Plus on the OpenVMS Alpha node, for what the
  network connection is, for what licenses (routing or end-node) are
  loaded, and for specifics on what you mean by "will not take".
  And expect to be asked questions about remote access to the node
  over the network, to ensure that the physical connection itself is
  viable and operational.  And expect to be asked if the OpenVMS Alpha
  system can connect to the OpenVMS VAX system.
 
  Also expect to be asked if the node is reachable using the numeric
  address.  To calculate the numeric address under DECnet Phase IV,
  multiply the area by 1024, and then add the node number.  eg: A DECnet
  Phase IV node with the address 19.22 would have the numeric address
  value of 19478.  You should be able to SET HOST 19478 to reach the
  node, in addition to using the node name associated with the node
  address in the DECnet node database.
 
  Within the DECnet Phase IV NCP utility, the usual approach to define
  a node in the node database is the following sequence of commands:
 
    NCP> DEFINE NODE aaa.nnn NAME name
    NCP> SET NODE aaa.nnn NAME name
 
  The first command writes to the permanent node database, while the
  second writes to the volatile (live) database.

  However, based on your posting of this question to the comp.os.vms
  newsgroup, the Wizard has learned that you are using DECnet-Plus on
  the OpenVMS Alpha system.  As a result, you do not use NCP to manage
  DECnet-Plus, you use NCL and tools such as the DECNET_REGISTER utility:
 
    $ RUN SYS$SYSTEM:DECNET_REGISTER
 
  As one of the responses to your question further provided:
 
    Assuming that your VAX node is named VAX001 and has 2.1 as address,
    type this on the Alpha:
 
    $ MCR DECNET_REGISTER /COMM
    DECNET_REGISTER> REGISTER NODE VAX001 DIRECTORY LOCAL PHASEIV VAX001
    TOWERS {TP4/2.1,NSP/2.1}
    DECNET_REGISTER> EXIT
    $ MCR NCL FLUSH SESSION CONTROL NAMING CACHE ENTRY "*"
 
    To copy the entire phaseIV database to DECnet-Plus, type this:
 
    $ MCR DECNET_REGISTER /COMM
    DECNET_REGISTER> EXPORT NODE * FILE NODES.DAT DIRECTORY PHASEIV
    DECNET_REGISTER> IMPORT FILE NODES.DAT DIRECTORY LOCAL
    DECNET_REGISTER> EXIT
    $ MCR NCL FLUSH SESSION CONTROL NAMING CACHE ENTRY "*"
 
  The text above is from Ferry Bolhar, and was posted to comp.os.vms
  in response to your question there.
 
  Alternatively, you can revert to DECnet Phase IV on OpenVMS Alpha V7.1,
  and use that.  (For information on support for DECnet Phase IV, please
  see the Prior Version Support area of the software support pages at the
  Compaq customer service website: www.service.digital.com.)
