Thank you all for attending the session on "Maximizing Availability in Virtualized Environments" during the SAMG Customer Forum in March 2012. I hope you would have found it useful.

We discuseed the following content during the session.

"Implementation architectures of VCS and ApplicationHA for virtualized environments. We reviewed common use cases and discussed how others are achieving maximum application availability in their virtualization implementations. This session provided information for VMWARE, Solaris Zones/LDOMs, AIX LPARs/WPARs and Linux KVM environments"

Again, thank you for your participation and hope to see you soon!

Regards,

Anish Vaidya

IT organizations have embraced virtualization as a way to cut costs and make their data centers more agile to respond to business needs.  However, application visibility inside VMware HA is nascent and can lead to disastrous failures.  Listen to this podcast, as Lorenzo Galelli, Sr Principal Technical Product Manager at Symantec, explains how you can confidently gain visibility and control of mission-critical applications inside VMware.

In my last post I mentioned a few common misconceptions about HA clustering that I'd be debunking; namely that it's unreliable, complex, and expensive. There are others that we'll get to in later posts, but for this one I want to tackle the myths of unreliability and complexity, since they kind of go hand-in-hand.
 
The vast majority of our customers using Veritas Cluster Server (VCS) for high availability have been using it for quite some time and are completely happy with it. But we do hear from time to time from customers who say they've used HA clustering in the past - either VCS or Brand X - and stopped using it because it "broke". Frankly, this reaction baffles me. As an IT guy who's been in the business for - well, let's just say a long time, OK? - I learned early on that if something worked yesterday...

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 of ancient...

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"...

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.

While virtualization brings many benefits, effective backup and recovery of applications in VMware environments has been a major challenge for IT organizations that are rapidly virtualizing their infrastructures. SearchServerVirtualization.com recognized Symantec's efforts to address this issue and awarded the Silver award for Backup Exec in the 2011 Backup and Storage category. 

 ApplicationHA and Backup Exec together provide automated recovery of virtualized applications from backup when the VMware Guest has been corrupted and cannot be restarted. ApplicationHA provides a three-tier recovery model  - Restart.  Reboot. Restore. - to recover from application failures in virtual envrionments. The proactive measures taken by ApplicationHA and Backup Exec together help organizations meet their stringent RTO requirements...
