[ClusterLabs] Antw: [EXT] Colocation per site ?

[Strahil Nikolov]

DC1:- nodeA- nodeB- nodeC
DC2:- nodeD- nodeE- nodeF
DC3:- majority maker
I will have 3 VIPs:VIP1VIP2VIP3
I will have to setup the cluster to:1. Find where is the master HANA resource2. Place VIP1 on nodeA/nodeD3. Place VIP2 on nodeB/nodeE4. Place VIP3 on nodeC/nodeF
End Goal:Master on nodeAVIP1 on nodeAVIP2 on nodeBVIP3 on nodeC
Master on nodeDVIP1 on nodeDVIP2 on nodeEVIP3 on nodeF
Master down:All VIPs down
I think that Ken has mentioned a possible solution, bit I have to check it out.

I think you should explain the scenario a bit better to undertsand what you want.
