@low944 wrote: So with HA between controllers, would I need to run setup on each controller module via serial? Yes, you need. You cannot setup HA without completing basic setup of both controllers first. You also need to assign some disks to the second controller at least for root aggregate. You may also need cf license depending on Data ONTAP version. ... View more

That’s not the normal steps at all. You never need to disable HA to power off systems (in general you should never disable HA on two node cluster unless following well defined procedure). I suspect OP confused HA and storage failover.   Because storage failover was not inhibited, one node is in failover. Now if it is also node that has epsilon (HA is disabled), this is really a problem. I agree, better open support case, it goes above normal forum level. ... View more

If this is new controller, there is no point in downgrading; just install desired version from boot menu. Downgrade is needed when you want to preserve data.   You may want to clean up disks before to avoid issues with label mismatch; if you have 9.4 installed currently, boot menu offers it as well. ...

If both nodes in HA pair fail, clients will lose access to data on disks, connected to this HA pair. Also clients will lose connectivity to cluster if LIF they use cannot failover to another HA pair. ... View more

Well ... you have two possibilities.   1. Use cables between nodes and switches as temporary interconnect. It is enough to ensure connectivity for a short time before you move LIFs to new switch. You will have two unused cables after you move the first switch.   2. Temporary enable switch less cluster mode. It means no ISL will be expected by ONTAP.    With high probability simply moving LIFs will work as well, but i’d Open support case to be sure. ... View more

You could temporary reconfigure cluster as switchless - it should not require connectivity between different adapter pairs. You can actually simply leave your cluster as switchless now when you have only two nodes, and avoid moving switches completely.   oh, and you must reconfigure your cluster as two-node now, otherwise failover won’t work properly. ...
