We're making some pretty big changes in how we deliver high availability and disaster recovery, and to do that, we have to change how we look at HA & DR. But in order to do that, we first need to debunk a few myths about clustering that seem to have crept into a lot of people's heads over the years.

 

This is the first in a series of posts I'll be putting up here at Symantec Connect over the coming week or so in which I'll lay out some common misconceptions of HA clustering and explain why they're wrong. Here's an example of what some people believe about clustering and which I'll refute over the coming days:
  • Clustering is unreliable
  • Clustering is too complex
  • Clustering is expensive
Sure, like any other myth these have their origins in someone's actual experience, but just like the mythology...

Easy IMF plugin to make a VCS agent IMF-enabled
================================================

1) Stop the VCS cluster
   # hastop -all

Note: The steps here are meant for education purposes only and
hence shutdown VCS. You can perform these steps by keeping
VCS online as well. Refer to the VCS Admin guide and
Agent Developer's guide for further details.

2) Let's write a quick VCS agent that starts the script myimf.sh
 
   # mkdir /opt/VRTSvcs/bin/ezimf
   # cd /opt/VRTSvcs/bin/ezimf

   # vi myimf.sh   (enter the following text)
---------------------------------------------------------------------------
#!/bin/sh

while [ 1 ]
do
        sleep 60
        /usr/bin/logger -p kern.alert "hello world from myimf.sh"...

VCS 5.1SP1 onwards supports intelligent resource monitoring in addition to poll-based
monitoring. Intelligent Monitoring Framework (IMF) is an extension to the VCS
agent framework. You can enable or disable the intelligent monitoring functionality
of VCS agents as needed.

The benefits of intelligent monitoring over poll-based monitoring are as follows:

  • Faster notification of resource state changes.
  • Reduction in VCS system utilization which enables VCS to effectively monitor a large number of resources.

Below is the list of VCS agents that support IMF.

Linux’s strong revenue growth in the past few years has shown that the increase in Unix to Linux migrations is not a fluke or a temporary cost cutting measure.  In fact, IDC is projecting that Linux revenues will reach $1B by 2012.1 

The article "Get the Power of Unix for the Price of Linux" explains how organizations can leverage the savings and flexibility of the Linux platform for their  enterprises without compromises.  Please click here to learn more.

I was fortunate enough during my many years in the military to have been assigned to fixed-base communications units, meaning it was only on rare occasions that I had to choke down those infamous MRE (meal, ready to eat) rations that the US military hands out to personnel deployed in the field. For those unfamiliar with them, an MRE is a big packet containing a full meal for one, typically with items like corned beef hash, freeze-dried fruit, crackers & jelly, and maybe an oatmeal cookie.
 
When MREs are handed out at meal time, everyone takes a look at what their particular packet contains and the inevitable trading begins: "Anyone wanna trade with me for my corned beef hash?" or "Hey! Did anybody get chicken ala king? I'll give you my tuna with noodles!" In the end, though, everyone just put Tabasco sauce on everything to make it edible, so it didn't matter what they got in the first place.
