Issue

  • SwitchInfoUpdateFailure_Alert were seen for all switches after ONTAP upgrade.
  • Switches are pingable via cluster CLI:

Cluster::> net ping -vserver <vserver> -lif <cluster_mgmt_lif> -destination <Switch_IP>
  (network ping)
<Switch_IP> is alive 

  • SSH to the switches is successful
  • If switch entries are deleted from ONTAP, re-adding results in IP address not reachable:

cluster::> system switch ethernet create-device <Switch_name> -address <Switch_IP> -snmp-version SNMPv2c-community-or-username cshm1! -model <Model> -type cluster-network    

Error: command failed: IP address"xxx.xxx.xxx.xxx" is not reachable. Verify that the address is valid,or check the network path.

  • Nodes no longer have node management LIFs.
