I have sql 2008 cluster environment: windows server 2008 enterprise sql server 2008 active/active/passive cluster. NODE1: Active: inst 1, inst 2. NODE2: Active: inst 3, inst 4. NODE3:Passive: inst1, inst2, inst3, inst4. Plan: Create ACTIVE(NODE1)/ACTIVE(NODE3). EVICT NODE 2 1.failover inst 3 and inst 4 to NODE 3. 2.install inst 3 and inst 4 on NODE 1. 3.Uninstall inst3 and inst 4 from NODE 2. 4.Evict NODE 2. Last time uninstall instance from a node uninstall from all nodes for sql 2012 cluster. If it happens what would be the best solution to avoid it. Any suggestion or ideas will be appreciated.
