Need some help with a FAS2520 2-node switchless cluster. Since some time one of the nodes appears in red (node down) in OnCommandSystemManager. Here's some commands output that I've managed to run (I'm a NetApp newbie, hope these make sense):

I've tried to reboot the failed node from command line, but:
ntapcl-bul-sf::*> system node reboot -node ntapcl-bul-sf-01 Warning: Rebooting or halting node "ntapcl-bul-sf-01" in an HA-enabled cluster may result in client disruption or data access failure. To ensure continuity of service, use the "storage failover takeover" command. Are you sure you want to reboot node "ntapcl-bul-sf-01"? {y|n}: y Warning: Unable to list entries on node ntapcl-bul-sf-01. RPC: Couldn't make connection Error: command failed: RPC: Couldn't make connection
Looks like a communication issue, there is no ping to any of the IPs of the failed node - not from a workstation, not from the second node.
What would be the right thing to do next? Is it safe to turn the power off/on , or reconnect all network cables one by one? Or something else?
Thanks in advance for the help!

Hi Team we have an issue on one of our netapp appliances. One of the controllers keeps faulting every 2 days. Only a hard reset seems to solve the issue temporarily. Some of the resources do stay online but the rest do not failover to the other controller. kindly Advise

Hi All, Actually, We have a FAS2750 10 Gb Base T for NAS services. Due to a network upgrading, we need to change our 1 gb base T connection per 10 gb SFP. Our Storage team are planning to change controllers FAS2750 10 Gb Base T per controllers FAS2750 UTA2 and we want to following the "Controller Module Replacement-FAS2700" from NetApp Docs. (https://docs.netapp.com/us-en/ontap-systems/fas2700/controller-replace-overview.html) As you know, for this escenario it is not possible change only ethernet connections to UTA2 SFP connections using adapter cards without changing the controller. My question is, will it work for us? Thanks for your support.

I have these components NetApp IOM12 (2) inside DS4243 connecting to Dell PE R620 with 2 H830 and 1 Dell HHJD7 ASA-80165H Quad port I need some instructions or guidance on how to cable these components together to get the server to see the NetApp box....I am not sure I want to run an actual RAID, but I definitely would like the server to see the NetApp box as JBOD set up....can someone please provide me this guidance?
