Number of hosts to power up for cluster memebership

[Xentar]

Hi All,

we have a 4 nodes VCS.

After shutdown all the 4 nodes and power up one by one, and we check with "lltstat -n", and "gabconfig -a".
We found that lltstat -n is normal, however, there is no output for gabconfig -a until we power on all 4 nodes.
If we issue gabconfig -c -x in one of the machine, the port a is generated, but the port h is not available until we power on all 4 machine.

We would like to know that how many machine we need to power on after shutdown all the machines in order for the cluster memebership to create?

Regards,
Xentar

Hi Xentar,

"gabconfig -x" should seed the cluster regardless of the availability of the other nodes.

If the had process was not running while issuing the above command a "hastart" is needed too.

I hope this helps.

If you want the cluster to start , regardless of the number of nodes ready to join the cluster, configure each node with a 'echo "/sbin/gabconfig -c -x" > /etc/gabtab'  (solaris,linux, 5.0MP3).

Hello,

This is an expected behaviour,  In an ideal situation whatever number you have provided in /etc/gabtab (usually equal to number of nodes in cluster), that many nodes are needed for cluster to seed.... otherwise full GAB membership won't be formed... & ofcourse HAD can't started unless GAB has formed membership..

If you want to force seed GAB, you need to use the options mentioned above i.e gabconfig -c -x

Hope this helps..
