Failover to anothe site
Posted on 2011-03-16
scenario is as follows:
1. We have a mixture of servers 2008 & 2005 on site A , about 15 of 25 Databases is mirroring
all of the databases is in Principal modus (on this site A)
2. As a test we are going to shutdown all the servers on Site A, and thus on site B which is (mirroring)
will automatically be Principal. ( High safety with automatic failover (synchronous) is implemented.
so far so good.
ON site B we will run a live test for about 2-5 hours. ( site A is still down and will be down during the test)
what will happen when we fire up SITE A..?
will site A automatically be a mirror site?
will all the data be sync?
How do I make site A (the principal) manually one and one or ...any other way.
Must I backup and restore on all the Databases?
Hope this is clarifying
