Subject Re: Production recovery procedure for VPC Virtual router into advanced zone - CS 4.0.0
Date Wed, 13 Feb 2013 20:30:30 GMT
Hey Benoit,

I queried some engineers inside the citrix qa team. They told me to try the
restartVPC api call. This should recreate the router. If it doesnt we
should log a bug, there should be a way to recover from this easily.
