What testing would you wish to carry out??

A single node cluster - would defeat the whole object of a cluster - were it
possible to do..
Which Mickey - correctly point out that you can not do..

Here is a copy of the man page for Hastart. Note the -onenode option.


Name

hastart - start the VCS server on the local system

Synopsis

hastart [-ts]

hastart [-ts] -stale

hastart [-ts] -force

hastart [-ts] -onenode [-port portnum]

hastart -help

hastart -version

Availability

VRTSvcs

Description

The hastart command starts the VCS server and related processes on the
local system. The VCS server and related processes then
automatically join the cluster.

Options

-ts
This option starts the VCS server as a time-sharing
process instead of as a real-time process.
-stale
This option instructs the engine to treat the local
configuration as stale even if it is valid.
-force
This option instructs the engine to treat a stale, but
otherwise valid, local configuration as valid.
-onenode [-port portnum]
Use this option only to run VCS on a single system on
which LLT and GAB are not installed. Do not use this option on a
multisystem cluster.
If this option is specified, hastart forks off a process called
GABSIM,
and the VCS server connects to GABSIM instead of GAB.
portnum is the number of the port used to connect to the
GABSIM process if the default port (14143) is not used.
-version
This option returns the version level of the software.

** Any opinion expressed is my own and not of my employer **

Another option for a 1-node cluster is to change /etc/gabtab. Instead of


/sbin/gabconfig -c -n2

Use
/sbin/gabconfig -c -n1

That says to allow the cluster to come up with 1 node instead of 2 (or however
many nodes you may have originally).


Hope this help.

It looked like the first post in this thread was after a SINGLE node
cluster - of one system - not a single node of a cluster ? - maybee i just
missed the point!?"

one node clustering will be available in the next version of VCS

Actually, you can do it, its just not easy.

your gabtab file needs something like..
/sbin/gabconfig -c -s -n1

and your llttab sets up a single link over the loopback or
some other interface.

As for why? Its good for testing of configuration files, failover behavior
and most importantly, self written agents.
