  • NVIDIA スイッチ

問題

  • ONTAPをアップグレードした後、スイッチヘルスモニタリングサブシステムが「不明」ステータスを報告し、検出開始状態でハングします。
    ログ出力の例:

::> system health subsystem show -subsystem switch-health -instance
   Subsystem: Switch-Health
   Health: unknown
   InitializationState: start_discovery
   Number of Outstanding Alerts: 0
   Number of Suppressed Alerts: 0
   Node: <Node-Name>
   SubsystemRefreshInterval: 5m

 

  • しかし、スイッチはSNMP経由で正常に監視されていました。

::> system switch ethernet show
Switch            Type         Address      Model
--------------------------- ------------------ ---------------- ---------------
NETAPP-SW1 (9X:XX:XX:XX:XX:XX) storage-network 10.xx.xx.xx MSN2100-CB2FC
   Serial Number: MT2302TXXXXX
    Is Monitored: true
       Reason: None
  Software Version: Cumulus Linux version 5.11.0 running on Mellanox

NETAPP-SW2 (8X:XX:XX:XX:XX:XX) storage-network 10.xx.xx.xx MSN2100-CB2FC

    Is Monitored: true
       Reason: None
  Software Version: Cumulus Linux version 5.11.0 running on Mellanox

   Version Source: SNMP

  • スイッチを削除して再度追加しても問題は解決しません

::*> system switch ethernet delete -device <device_name> 
::*> system switch ethernet create -device "<DEVICE_NAME> (<MAC_ADRESS>)" -address <IP_ADDRESS> -snmp-version <SNMP_VERSION> -community-or-username <COMUNITY_OR_USERNAME> -model <MODEL> -type <TYPE> -is-monitoring-enabled-admin <TRUE_OR_FALSE>

  • 「cshmd」を再起動しても、開始検出フェーズで停止します
