HA Configuration: Interconnect Status is DOWN on both Filers

ASRARGUNA — Thu, 05 Jun 2025 06:02:39 GMT

Hello All,

I am in some trouble here and would appreciate some help in resolving the issue.

I have 2 Filers: Filer1 and Filer2 as HA pair. Both are FAS3160 model with 8.1.1 7-mode running. When I login to On-Command system manager and go to "HA Configuration" It shows Interconnect status under both filers as Down (red X). Under Active/ Active State, it shows Failover under Filer1 and Takeover under Filer2. Please check the screenshot attached.

How can I get the HA config back on my filers?

Thanks - AG

Are the two physical filers up and running? Please check by logging to the console.

Thank You ALeksandar for your reply.

Yes, both Filers are up and I can ping both filers from my pc. I can also connect to both filer through on command system manager and work on volumes, etc. Only HA is showing as in the attachment earlier.

I also did SSH to Filer-2 and this is what I get there.

Yes, but Filer-2 is in takeover mode. How are the two filers connected between them? Check the cables.

Unfortunately the filers are at a remote location so I can't check cables. Is there a way to check things remotely? Sorry.

If the cables are disconnected you will just see ports offline without knowing what is going on.

execute ifconfig -a on both filers to see if interconnect ports on both filers are down.

I am not able to SSH to Filer-1 as it says "Shell not supported on takeover partner"

On filer-2, this is the result of ifconfig -a
