My issue is if shutdown entire cluster I will need to power-down 270+ VMs. two nodes and 11 shelfs are half of the cluster. The disk shelves, I need to power-down are only connected to the nodes that will be relocated. So my questions is it possible to run the cluster with with other pair and it disk shelves while other two down.
Ex: Cluster has node a and node b - HA pair with disk shelfs 00-04 and node c and node d HA pair with disk shelfs 30-36. I want to shutdown node c and node d HA pair disk shelfs 30-36 to relocate. Can I just shutdown node c and node d with their disk shelfs while node a and node b running with shelfs 00-04?
Can I just shutdown node c and node d with their disk shelfs while node a and node b running with shelfs 00-04?
Yes and now. To be fully functional cluster needs quorum - more than half of nodes. If you lose exactly half of all nodes, remaining nodes will retain quorum thanks to epsilon. But when you power on half of the nodes on another location, they will not be usable until quorum is attained, so no access to data on these nodes will be possible. So at the end you gain nothing.
So yes, you can shut down one HA pair. No, you cannot bring this HA pair up on another location separately.
To be clear, I will not create a new cluster. After relocation nodes and disk shelves will be in the same cluster as before the relocation. Cluster will be same as before relocation but nodes c and d will be in different rack with their shelves.
