Network inconsistency during takeover

scarmic76 — Thu, 05 Jun 2025 06:13:02 GMT

Hi everyone, and happy new year.

This morning one controller of a 3140 HA pair fault, so the other takeover disks and network interfaces.

There is a problem: an ip address of the first controller (nas1) is lost.

This is what I get when I run ifconfig on the second controller (nas2):

vifs0: flags=4948043<UP,BROADCAST,RUNNING,MULTICAST,TCPCKSUM,NOWINS> mtu 1500

inet 20.0.0.102 netmask 0xffffff00 broadcast 20.0.0.255

partner 20.0.0.101 (not in use)

ether 02:a0:98:11:1a:1d (Enabled virtual interface)

the ip 20.0.0.101 assigned to nas1 is lost. What happened?

How can I force nas2 vifs0 to correctly takeover that ip?

Any suggestion?

Thank you very much and sorry for my bad english.

Michele

Hi - have you tried running the Cluster Config Checker or the HA Config Checker within OnCommand Systems Manager?

This tool will check the current config and config of you RC files to make sure they are correct for a HA System.

Are you able to paste the contents of the RC file into th thread?

For vif you have to use partner vif name, not the IP address, in 'partner' option

Yes, this is the reason of the misconfiguration.

Thank you very much, now it's all ok.
