Creating a new cluster

[Craig Johnson_1]

I'm new to Serviceguard and haven't had any training on it yet, but I'm trying to build a cluster anyway. So far I've built a good MCOE system and cloned it using Ignite, and have gotten as far as running "cmquerycl" and editing the resultant ASCII file.

What is my next step (and the steps after that)? I'm trying to read the manual but it is 500 pages long and much of it doesn't really apply.

I do have EMC disks available for use as quorum.

Thanks in advance for your help!

Shalom,

RTFM. Its the best way to learn.

Assuming you got good results from the last step.

cmcheckconf
cmapplyconf

But you';ll need to have a configuration file, which you will need to edit.

Can anyone help with an EMC question? The second server, which was clone from the first, seems to be masking the first from the EMC hardware.

I can't find any configuration files for the EMCpower stuff. Do I have to uninstall/reinstall it on the second box?

The fiber switches use the servers FC cards mac adresses, so your cloned second server should not see the hardware until the correct mac addresses (which are different on your cloned server)be setup in your fiber switch

If you are setting up two node cluster then ask your SAN storage guys to zone, mask EMC disks for these nodes.

You can use smallest EMC disk for quorum. Make sure that you do use same device file name on cluster ASCII file otherwise you do get cluster compilation problem.

Setup VG's, filesystems for packages on one node and take maps in preview mode, copy them to second node and import them.

What I'm seeing is this:

Server A
Server B (cloned from A)

If B is down, the EMC console can see A, but if B it up, it masks A. Hostnames and IP addresses are correct in /etc/hosts files. Does the EMC "ecc" master agent keep a copy of the hostname somewhere else? I guess I shouldn't have installed it before cloning with Ignite?
