relationship between SCSSYSTEMID and decnet address
I would like to know if there is any relationship between sysgen parameter SCSSYSTEMID and decnet address.
As observed in my environment, the two values are in general the same for the VMS systems.
Is it required also to update the SCSSYSTEMID if i am going to change the decnet address?
And, if i have to change the SCSSYSTEMID, what associated changes I have to applied to the clustered nodes?
Best Regards,
Patrick.

Re: relationship between SCSSYSTEMID and decnet address
Yes. SCSSYSTEMID = (DECnet area *1024) + node number; thus, DECnet address 1.1 = SCSSYSTEMID 1025.

Re: relationship between SCSSYSTEMID and decnet address
To change the ID, make the change in MODPARAMS.DAT, run AUTOGEN to set the new value (one could do this via SYSGEN, but that's bad form), and reboot. The system will join the existing cluster, assuming the SCSSYSTEMID is unique in the same cluster. If you change the DECnet address, the SCSSYSTEMID should be changed also.
If DECnet is not used, which is becoming more and more common, and TCPIP is the only protocol, then the SCSSYSTEMSIDs of the clustered systems can be arbitrary, as long as they are unique within the cluster authorization scheme.

Re: relationship between SCSSYSTEMID and decnet address
So if you change SCSSYSTEMID and don't want to also change SCSNODE (which matches the DECnet node name and TCP/IP nodename) at the same time, do your AUTOGEN (as described in an earlier reply) to change the SCSSYSTEMID value for the next boot, then shut the node down and keep it down while you reboot any other cluster nodes with memory of the old SCSSYSTEMID/SCSNODE combination.
$SHOW CLUSTER/CONTINUOUS with ADD SYS_ID will show what node(s) a given cluster node is aware of having been in the cluster in the past, and what the node's SCSNODE (under the "NODE" heading) and SCSSYSTEMID ("SYS_ID" heading) values were at the time. (A node which has left the cluster is shown with "BRK_NON" under "STATUS", indicating that it is a non-member of the cluster after a "long break" in communications.)

Re: relationship between SCSSYSTEMID and decnet address
If you show your decnet address in DECNET_REGISTER. It lists the MAC ADDRESS that is seen by the network switch on the primary network port. Not the MAC address embedded in the NIC.
So, if you change your DECNET address. Let your network folks know that your MAC address associated with your IP adress will change.
