Hello all..
I've recently started trying to learn about vms and have managed to get a cluster up and running. I am using simh for this purpose. Currently, I have a pi3 set up as a cluster boot server (and disk server)
All other nodes boot as satellites. I have 1 pi2 satellite, and 3 other nodes running under an ubuntu vm (using an unraid box, with 10 threads assigned to it)

I've gotten the hang of adding new nodes, have modified the correct include file for params to set intstkpages so that tcpip will work. But my question is this..

When I add a new node, I end up having to use ncp to copy known nodes around so that the new node will be recognized (using phone for example.) I'm sure I'm missing something.. Is there a way to have known nodes automatically propogate to all nodes?

I do have other things working, like the disk that holds my user accounts mounts correctly on all nodes, but I can see it being a real pain updating all nodes in a cluster so that they can all see each other.

Another question.. When setting things up, there is a question about a cluster setting (I've blanked on the question at the moment,) basically the question is about having the cluster appear as a single system. I've answered yes to this, but don't yet understand enough to see a difference. I can still telnet into an ip and end up on a specific node. Can anyone point me to some cluster tutorials/info written for a complete newbie?

Thanks in advance for any and all pointers,
S.M.

Hello sturgismike , Having not found anything with "Tutorial" in its general content thru Google .
I did find this (a DEC) Document on Clustering in Openvms 7.3 , Something , I am sure since you have already created a Cluster , Have reviewed . But anyway ...

https://www.itec.suny.edu/scsys/vms/OVMSDOC073/v73/6318/6318pro_contents.html

Have you gotten your Decuserve account , if so Try typing notes at the command line .

At one time, didn't this web site have a job board? I would love to use my legacy skills one last time in my career.

Hi all, haven't been here in years. Good to see it is all there still. I'm looking around at the forum to stop/start msipcap - 'could not be stopped' - for now. I'll shutdown FreeA
