Looking to deploy SnapManager Hyper-V on our 3 host cluster and just looking for some clarification on a few things.
We have a 3 host Hyper V cluster that connects to the same Failover Cluster and 6TB CSV to store the VM's. I know I need to install SnapManager Hyper V on all 3 hosts. When I connect to a host in SMHV, I connect to the name of the Failover Cluster and not the 3 individual hosts. This makes sense.
What I am confused on, when I create my Dataset and add the VM's, the VM's will exist on 1 of the 3 hosts and with LiveMigration, they can move around. When a DataSet policy kicks off, what host is taking the backup? The host that owns the VM?
In 2012, the documentation says it supports CSV for SnapInfo LUNs, but then goes into making a cluster group called "smhv_snapinfo" which really isn't a CSV and just an additional Role in Failover Cluster Manager. With a 3 host Failover Cluster, this "smhv_snapinfo" role will only be owned by one of the three hosts, and thus the disk associated to it, will only appear on the single host that is the owner. Does this mean, whatever host is the owner of the "smhv_snapinfo" role, will take the backup of all the VM's...even if the VM's exist on the other two nodes that arent the role owner?
If I move the SnapInfo LUN to a CSV...this will be presented to all 3 hosts. What host will be responsible for taking the backups when the Dataset Policy kicks off?
Just a little confused on this operatiblity, and I can't seem the find the explanation. Just looking for some clarification on this process? Let me know if I am missing a document that goes into this, etc.
