Service Guard Quorum Server. Can it be a workstation?

[Steven E. Protter]

Question in Service Guard Class has us all stumped. Though SG can't be done with workstations what about the quorum server?

Must it be a server or can it be a workstation.

A quorum server handles tie breaking mechanisms when heartbeat is lost.

Hi SEP,

Well although functionally it could - I believe HP may not support it. They seem to shy away from workstations for all things MC/SG, IMO.

Rgds,

When installing MC/SG on the workstation, it will fail because it is not an HP9000/800 series machine, as that is a prerequisite. I tried once a long time ago.

hth!

Thank You Jeff,

Looking for a doc or...

I tried it and it works.
I tried it and it doesn'nt.

I don't have an HP-UX workstation handy to load the QS on but I know that a Linux workstation with QS A.02.00 will serve an HP-UX MC/SG Cluster (or a Linux MC/SG Cluster). My best guess is that it will work since the QS is outside the cluster itself.

So, (admittedly cheating, but it ain't my fault you didn't precisely frame your question) a Linux workstation will definitely work; an HP-UX workstation will probably work.

Hi (again) SEP,

Attached are the QS_A02.00 release notes. I note *no* system type requirements other than HP 9000. I also find no statements in their about whether HP supports QS on 700 series systems. So I'd have to believe it would work *and* be supported.
Do note however that they *do* recommend the QS be on the same subnet as those clusters being monitored & and I don't know about your networks, but here we run our workstations on diff subnets than our servers.

HTH,
Jeff (who should quit making assumptions)

Doc question is closed.

Another bunny is available to anyone that is actually doing it on a workstation. Every have to call the response center? Did they help.

Good Work esteemed colleagues.

Actually the Release Notes do say:

The HP-UX Quorum Server runs on an HP 9000 and on Integrity servers. The Linux version runs on Compaq Proliant servers and on HP Net Servers, if the operating system is supported by HP for net servers.


So it is for servers. not workstations.
However, I cannot see any real reason why, and will try to check this up later this week.

SEP,

I am not running Quorum Server on a workstation.

But I do not see what difference it would make. It is just a daemon process which is spawned by init to which the ServiceGuard nodes have to be able to connect to. (so more likely you could have a network issue)

You do not need any part of MC/SG on the quorum server.

Like Clay said you could have a Linux box as a quorum server for HP MC/SG cluster; I did the opposite, i.e. using a K200 as a quorum server for a MC/SG Cluster on Linux machines. It works.

Regards,
Bernhard

Now I am thoroghly confused.

We don't have a workstation to test on here in Downers Grove.

Someone want to try installing the quorum server peice alone, not the full SG on a workstation.

A bunny for a test.
