    Shawn Jackman (Jack) CWNE#54 is a personal friend and has been a mentor to me for many years.  I've had the pleasure and opportunity to work with Jack for 4 years. Jack is a great teacher who takes complex 802.11 standards and breaks them down so almost anyone can understand the concept at hand. I'm excited for you brother. Great job and job well done! Put another notch in the belt!

WCS: WCS HA FAIL OVER – HOW TO MANUALLY FAIL OVER!? – DID YOU KNOW?

I’ll save you a call to TAC … How to fail over your WCS server in HA mode manually..

I initially thought, shutting down the primary WCS gracefully it would failover to the secondary WCS. It didn’t.

WHAT I LEARNED …

If you shut WCS down gracefully “StopWCS” she doesn’t failover. In fact, either you have to pull the cable or hard shut down the server for the WCS to failover.

TESTING WCS HA FAIL OVER

If you want to test WCS fail over from your primary to secondary WCS server enter the following command in the primary WCS server CLI:

/WCSROOT/bin/nmsadmin.bat -switchover stop

ENJOY!
