Cluster failover check script

[James Nowak]

I am trying to write a script that checks the VGs of the various nodes to ensure that a package can fail over successfully without issue.

I need to accomplish these things:

- Ensuring the package can mount all of its filesystems in its /etc/cmcluster/package/package.fstab file

- Ensuring the package.fstab file is identical on all nodes

- Ensuring the package VGs are included in the cluster config

I'm looking for something I can cron for a weekly check or so.
Any help is appreciated.

James,

If its an option, why not just purchase HP's cluster consistency service, which will deliver an implementation of the Cluster Consistency Monitor. It checks the stuff you described plus much more, and I don't remember it being particularly expensive...

What you really need is CCMON:

Interesting stuff this CCMON (haven't heard of it before) though I doubt if it is really that realistic to always being required to have an HP engineer fixing the baseline config.
For many of our clusters they quite frequently undergo continuous changes (from adding or removing disk storage to integration of new packages/services or total restructuring) which of course are performed by us Unix admins or even the database admins (of course those who have the experience of cluster maintenance and are trustworthy ;-)
Many of these modifications and enhancements are performed on Sundays or off business hours.
I would find it pretty limiting if I always had to fix an approval date with an HP engineer, as the contract seems to imply.

How it works is, you pay with 1 technical services day, they give you a license, then away you go - no need for HP to do anything after the original install. You can make template changes and so forth.

CCMon is a piece of software that HP offer as part of a service ( I think th eproduct number is HA243A1, and covers a 2 node cluster, with one of installation, basic setup, and overview to the customer.
As there are so many different things, a basic configuration setup is done, a report generated, then something is added in, like a pacjage for SG, and the report rerun, to show you how you can make the changes.

Take a look here:

forgot to say, there are two variations, one is the Assesment, which is where a Consultant will come out, run the report, then remove the software. This uses a temporary license.
The other Service you pay for a permanent license and then you as the customer make any relevant changes and run the reports as and when you wish.
