I'm trying to design the network topology for our new FAS2620 two node HA pair running 9.2. At this point it's likely we'll run active/passive.
My intention is to to create a LACP network pair on each node for the data path, and put the primary node on one switch cluster, and the secondary node on another switch cluster.
The switch clusters are Aruba/HP ProCurve 2920 systems, where the only true single point of failure is the switch stack software, OR when I update the switch stack code, and that takes about three minutes, which brings the stack down during that time.
With the LIF and node failover policies available to us in Ontap 9.2, if the switch stack connected to the primary node goes down resulting in a complete lack of connectivity to the data path of the primary node, is there a way to get the passive secondary node to take automatically take over in some way, either through full failover, or just grabbing the lif?
If this isn't possible with active/passive, is it possible with active/active?
I've read the docs, but my naiviety made them a bit opaque as to this particular scenario.
