[Info-vax] Changing VMS node name

[JF Mezei]

A VMS node has different node names.

There is the SCSNODENAME  which names the node in a cluster and provides
a 6 charater nodename.  This is defined in SYSGEN  (but you should
define it in sys$system:modraparm.dat and then run
@sys$update:autogen getparams saveparams to have autogen apply the stuff
to sysgen for you)


There is the DECNET node name which names the node for decnet network.
(note that there is a strict association between the DECNET node number
(area and node) and the SNSNODEID . (this is fairly well documented in
help I think).

Frankly, the easiest way to fix this one is to start from scratch.
@sys$system:netconfig and re-enter everything. This will be faster than
learning all the MC NCP commands to fix the node, executor etc.


There is the TCPIP node name as well.
Easiest way is @SYS$MANAGER:TCPIP$CONFIG.COM

All these 3 are defined separatly and reside in different databases.


For SCSNODENAME you absolutely need to reboot. And it won't let you
reboot just that node if you are in a cluster. (you'll have to reboot
all other nodes so that they forget about the old  SCSNODENAME/SCSNODEID
 combination and allow the new one to join the cluster).

For DECNET and TCPIP services there are ways to change the configs
without rebooting. BUt it is often simpler.
