cluster management ports stopped working

roombabu — Wed, 04 Jun 2025 19:39:57 GMT

Hi all,

I've configured cluster management ports on the same lif where data is being transfered. but I've associated the cluster management port with node admin vserver.

Also what I did is that I've created A-records and ptr for the cluster management port so that I can have one dns entry for two ports(ip addresses)

Cluster management port was working fine but a day later they stopped working. Neither me nor the other teams made any changes.

I have to do this because, I have just 2 ports per controller on my fas2520 dual controller system switch-less cluster. if I dedicate a0a for cluster management, then I will be left with e0b (1gb), thats just one port.

I cannot use e0c (no 10gb capable switch)

Please let me know if you notice something wrong in my configuration. I ran it through config advisor and everything passed.

I dont see a cluster management LIF in this output at least the way it looks like in standard deployments. Did you rename the LIF after creation?

Can you post the output of the following command?

cluster::> net interface show -role cluster-mgmt

hi there,

sorry it has been a while...

I fixed the problem by reconfiguring the entire setup. It was because I was given a bad gateway ip address. once replaced it, everything started to work.
