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):
ntapcl-bul-sf::*> cluster show Node Health Eligibility Epsilon -------------------- ------- ------------ ------------ ntapcl-bul-sf-01 false true false ntapcl-bul-sf-02 true true false 2 entries were displayed.

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!

Hello! I have a FAS8020 SAN cluster with two DS2246 shelves running ONTAP 9.1P19. This thing is out of warranty and we currently just use it for backups. I had a bad drive happen the other day. Didn't think much of it as I've replaced drives dozens of times. Popped the drive into the shelf; went into the OCSM GUI; saw the new drive and added it to the node. It sat there infinitely trying to add the drive. I thought it was just taking awhile, until an hour later, I finally realized I lost the entire SAN! I manually consoled into the cluster, sure enough both nodes went completely down hard. Saw this error on both nodes: PANIC: Illegal Disk Configuration in SK process config_check on release 9.1P19 Naturally, I removed the disk and manually booted the nodes one at a time in the CLI (via console). Everything came back up ok. Luckily we bought 2 drives so I thought maybe we had a DOA. Nope. 2nd one did the same exact thing. So my question here is, do I have a hardware incompatibility issue or a san configuration issue? Based on this error, I would assume it would be an incompatible drive. We tried to buy the same drive as what was in there (HGST SAS 450GB 10K Model: HUC109045CSS600). I'm not sure if there is a different spec I need to check? Fits perfectly. I think the shocking thing is that it takes the whole SAN down. I would have thought it would take one node down but not the whole thing at the same time! So I'm not sure if there isn't a configuration issue somewhere too. Appreciate any help. Let me know if I am missing any details. Thanks!

Hey guys - Can anyone with an 8040 post the Processor type from a "sysconfig" command? I need the exact CPU model number for some things I'm working on - need independent confirmation of something my NetApp team told me. Thanks in advance! Bob

I am trying to run a .ps1 script given to me by higher level. Factory Reset the storage system as directed using a macro file. When deploying the environment, fails to assign the first aggregate disk to node 1. Is there a command or setting in Data Ontap 8.3 that will allow/disable changing of node ownership of aggregate disks?
