Setting up a backup machine

[Robert Gezelter]

Peter,

It will also likely be necessary for the DECnet address/name and the SCSSYSTEMID/SCSNODE.

Peter,

the OpenVMS FAQ has a chapter about this:

5.7 How do I change the node name of an OpenVMS System?

The copy of the OpenVMS FAQ at HP is two editions back or so.

The "most recent" FAQ update is here:

For this question, also look here:

for "Changing the Node Name of an OpenVMS Host".

I didn't see anybody mention this suggestion yet: build a 2nd root on the system disk and pre-configure it as if it's going to be a cluster member. Then when you boot the copy, boot from the 2nd root into conversational boot mode and disable clustering. Then you can bring the system on up and finish configuring it. This way you still have the original configuration available for a quick reboot to the 1st root.

If you have a mirrored system disk and you are able to shutdown, then just replace the mirror with a new disk, and use it as the system disk on the new machine - isolate it before booting and change the network configuration from the console.

If you intend to make this a drop in replacement, copying the system disk and the other discs will work. But you will probably need to sue the VMS distribution CD to "clone" the system disc. If you boot the CD, it brings up a menu and that is one of the choices, to make an image backup of a disc.

If you want this computer to be available on the network, you will have to change DECnet addresses (sys$manager:net$configure.com), IP addresses (tcpip$config), modparams.dat, maybe licenses, etc.

If you want to make this an application failover / backup, you might get away with changing some logical names and so forth. So it depends on how far you want to take this. If I had a complete spare like that, I would probably want to VMScluster it and setup the application to run on either machine, if one or the other broke down. That is a lot of work though and perhaps a drop in replacement would be the easiest route, at least initially.

Ok i changed the hostname and the ip address on the interface but when i rebooted the system it came up with the old address and hostname.
Guess i need to change some startup / parameter files anybody know which ones??

Thanks

The procedure to change a nodename (and SCS ID) is laid out in the VMS FAQ at

Peter,

from your Forum Profile:


I have assigned points to 193 of 248 responses to my questions.

Most of those date back to 2004!

Maybe you can find some time to do some assigning?

http://forums1.itrc.hp.com/service/forums/helptips.do?#33

Mind, I do NOT say you necessarily need to give lots of points. It is fully up to _YOU_ to decide how many. If you consider an answer is not deserving any points, you can also assign 0 ( = zero ) points, and then that answer will no longer be counted as unassigned.
Consider, that every poster took at least the trouble of posting for you!

To easily find your streams with unassigned points, click your own name somewhere.
This will bring up your profile.
Near the bottom of that page, under the caption "My Question(s)" you will find "questions or topics with unassigned points " Clicking that will give all, and only, your questions that still have unassigned postings.
If you have closed some of those streams, you must "Reopen" them to "Submit points". (After which you can "Close" again)

Do not forget to explicitly activate "Submit points", or your effort gets lost again!!

Thanks on behalf of your Forum colleagues.

PS. - nothing personal in this. I try to post it to everyone with this kind of assignment ratio in this forum. If you have received a posting like this before - please do not take offence - none is intended!

PPS. - Zero points for this.

Proost.

Have one on me.
