Hi,
Please consider the following scenario, as we are conducting testing. I've
done my research and received varying information from support , so I
thought to get this audience's take on this.
Basically we have a flexpod.
- 2 cabinets;
- Each cabinet consists of: CN1610, Nexus, FI, 2 x FAS8020 (cDOT 8.3.1P1),
UCS blades;
- Controllers are joined together in a 4-node cluster configuration;
- Cabled in such a manner that we have controller HBA and switch port
redundancy.
If we were to shutdown a controller pair (2 nodes that are HA partners to
each other), effectively shutting down 1 of the 2 cabinets.
- Will the data on the disks attached to the other two controller nodes
(the surviving HA pair) still be served and accessible?
- What happens if epsilon resides on one of the nodes that are shut down.
Will it be automatically shifted to a surviving member in the cluster?
Thanks.
