  • ONTAP 9
  • クラスタスイッチ健全性監視(CSHM)
  • BES-53248

問題

  • クラスタスイッチのヘルスモニタアラート

Node-01: cshmd: hm.alert.raised:alert]: Alert Id = SwitchSNMPCommunication_Alert , Alerting Resource = sw1 raised by monitor ethernet-switch

  • 監視対象のクラスタスイッチでSNMPの無効な設定が報告されました。

::> system switch ethernet show
Switch            Type              Address          Model
--------------------------- ------------------ ---------------- ---------------
sw1              cluster-network    10.xx.xx.xx    OTHER
     Serial Number: Unknown
      Is Monitored: false
           Reason: Invalid SNMP Settings
  Software Version: Cisco Nexus Operating System (NX-OS) Software, Version 9.3(4)
    Version Source: CDP

sw2             cluster-network    10.xx.xx.xx    OTHER
     Serial Number: Unknown
      Is Monitored: false

  • スイッチを監視対象から削除して追加し直すと、次のエラーで失敗します:

Cluster::*> system cluster-switch create -device sw1 -address 10.xx.xx.xx -snmp-version SNMPv2c -community-or-username cshm1! -model OTHER -type cluster-network -is-monitoring-enabled-admin true

Error: command failed: SNMP validation request timed out. Verify that the "-community-or-username" parameter is valid.

  • 次に示すように、クラスタからのSNMP walkが「Operation timed out」エラーで失敗する

Cluster::*> systemshell -node * -command "sudo /usr/bin/bsnmpwalk -n -s cshm1\!\@10.xx.xx.xx -v 2 .1.3.6.1.2.1.1.9.1.2.1"
(system node systemshell)

Node: Node-01
bsnmpwalk: Snmp dialog: Operation timed out

Node: Node-02
bsnmpwalk: Snmp dialog: Operation timed out
2 entries were acted on.

  • クラスタ スイッチ IP は ping 時に管理ネットワークから到達可能であり、管理ネットワークと同じサブネット内にあるため、ファイアウォールまたは到達可能性が除外されます
