Cluster with 11.i

[Oliver Schmitz]

Hi all together,

we used to use with 10.20 an clusterconfiguration: One server and four clients booting their os from the cluster. The big advance was and is with 10.20 that one can install os for the clients different from the servers' one.

Now we have our new 11.i TCOE running and I do not find the appropiate cluster thingy to do so again with the newer os. Is it not possible anymore at all?

If yes, does anybody of you know another way to install 10.20 as the os of some networked clients (I saw the remote boot facility but no more the possibility to create the shared roout as we did under 10.20)?

Thanks in advance for some hints.

How about Ignite?

/opt/ignite/bin/ignite


MC/Service Guard?

Oliver,

Are you referring to a diskless cluster, by any chance?

Oliver,

I believe NFS diskless cluster's are still available. Check the section "Setting Up and Administering an HP-UX NFS Diskless Cluster" in "Managing Systems and Workgroups: A Guide for HP-UX System Administrators", available here:

http://www.docs.hp.com/hpux/onlinedocs/B2355-90742/B2355-90742.html

Hi Oliver,

I think you may be refering to diskless clusters. From the 11.00 release notes:

* Diskless clusters are not supported in HP-UX 11.0. The swcluster command is no longer supported. Any system updated to 11.0 must be a
stand-alone system.

Doesn't sound too promosing for you.

I believe you are referring to what was known as NFS Diskless at 10.20.
If so, this is no longer available at 11i of HP-UX.

Hi Oliver,

I believe what you were using was bootp & the associated bootpd daemon.
This lives in /etc/inetd.conf & the line looks like

bootp dgram udp wait root /usr/lbin/bootpd bootpd

Make sure that's uncommented & make sure none of these boot clients is not in /etc/dhcpdeny but IS in /etc/bootptab database.
You should be able to bring that db info over from the 10.2 system if you still have access to that data - else you'll have to re-enter it.
See man bootpd for further detail.

HTH,
Jeff

Oliver,

Sorry to confuse the issue, but I'm confused. The release notes seem quite definitive in saying that diskless clusters are no longer available, yet a search of docs.hp.com comes up with several hits like the following:

"Setting Up and Administering an HP-UX NFS Diskless Cluster (HP-UX 11.0, HP-UX 11i v1, HP-UX 11i v1.5, HP-UX 11i v1.6)"


I suggest you check out the link I gave you earlier to see what you can find out.

Dear Pete,

it seems to as unfortunately more often than one wishes not clear what is supported and what not.

I looked to your link and found the same diagreement in HP's docomentation.

Nevertheless I will now try another solution (may be you or anybody else can give me some information about your own experience with such matter) and dchpbootp the os 11.i to the fixed address of my client. If this will work I try to install the libraries (taht are SICL libraries for embedded instrument control) and will try to recompile my programms (I know because it should be binary compatibel I could compile it with the old server and use it on the new one, but we have to do continous developement) and try to run it. This should work even we do a lot of registerbased programming, because the old only 32 bit client will run the programm. Does anybody have some experience with this things and can give me any hints even if they should tell me to stop it and run not into a black alley.

Thank you very much for all the hints.

By, Oliver
