環境

  • クラスタ ネットワークスイッチ(CNS)Broadcom BES-53248
  •  10Gと40Gの異なる速度でクラスタポートが実行されているスイッチクラスタ

問題

  • 別のプラットフォームから既存のクラスタに新しいノードを追加するときにエラーが発生しました。例:
Cluster network RPC communication test from local address 169.254.99.130 to 169.254.247.154
Error: Cluster network RPC communication test from local address 169.254.99.130 to 169.254.247.154 failed with subsequent larger RPC request of size 1024 where size 0 succeeded. Possible MTU mismatch on cluster network ports or network switch. 
Reason: f_echo_1: RPC: Timed out; netid=tcp fd=253 TO=5.0s TT=5.001s O=1076b I=0b CN=275/2 VSID=-3 169.254.99.130:40455 <-> 169.254.247.154:7815. Verify the network configuration.
