Answer

  • ic.HAInterconnectDown occurs every hour when the high-availability (HA) interconnect is down.
  • If the HA interconnect link status is restored before the next top of the hour, the ic.HAInterconnectDown event will not occur.
  • Since the callhome ASUP is driven by the ic.HAInterconnectDown event, it will also not be triggered.

Tue Feb 20 13:25:33 +0900 [Node-02: mgmt_port_link_status_poll: netif.linkDown:info]: Ethernet e0a: Link down, check cable.
Tue Feb 20 13:45:07 +0900 [Node-02: mgmt_port_link_status_poll: netif.linkUp:info]: Ethernet e0a: Link up.

Additional Information

  • See ic.hainterconnectdown events
  • If the HA interconnect link status is not restored before the next top of the hour, then it will result in:
