How do I change a passive node to an active node?
How do I change a passive node to an active node?
Current Situation
SQLCluster1 SQLCluster2 NOTE: Both C1 and C2 are separate servers
SQLVCluster1 SQLvCluster2
Active
Passive
Current Resource Groups
Q:\ Quorum
R:\ Database Data --- In use
S:\ Database Logs --- In use
T:\ WebCT Data ---------- Available for use
U:\ WebCT Logs ---------- Available for use
Where We Must Be
SQLvCluster1 SQLvCluster2
Active
Active
We have no money for new Severs, SANs, etc., until July 1st 2010.
So, I must turn SQLvCluster2 into an Active node – I have no other choice!
I would greatly appreciate the help of anyone who can assist me.
Thank you,

- Once you add the resources to the new group you can rt-click on the group and select move group to move those resources to the other node.....For example:Cluster Group 1:Possible Owners: SQLCluster1, SQLCluster2Resources:QuorumCluster NameCluster IPCluster Group 2:Possible Owners: SQLCluster1, SQLCluster2Resources:R-driveS-driveVIPNameSQL Service (MSSQL Server)AgentetcCluster Group 3:Possible Owners: SQLCluster1, SQLCluster2Resources:T-driveU-driveVIPNameSQL Service (WEBCT Instance)AgentetcNow you can make sure that cluster group 1 and 2 run on the node SQLCLuster1 while cluster group 3 will run on SQLCuster2. This is an active-active cluster that will use the horsepower of both servers. In the case of a hardware failure the groups that are on the failed node will fail over to the other node.... allowing both instances to run on a single node during the emergency.... You may get a performance hit at this time, but you will not be completely out.

- Create a new cluster group and add the resources you want to run on the other node. Each cluster group can then be failed over independantly.
- Ok, so just by adding a new cluster group is going to turn my Passive node into an Active Node? I don't understand how that will happen.
