Symptoms

當使用者執行命令「isi services -a/-l」以列出在叢集上執行的服務時，會收到以下錯誤：

Cluster-2# isi services -a
Available Services:
lwmsg_call_dispatch failed: 16

 

Cause

這是因為 mcp 程序並未在叢集上執行。

 

Resolution

  1. 檢查 mcp 程序是否在叢集上執行

    Cluster-2# isi_for_array -s ps -auxww | grep -i mcp | grep -v grep
Cluster-2#

  2. 在叢集上啟動 mcp 程序

    Cluster-2# isi_for_array -s isi_mcp
Cluster-2#

  3. 驗證 MCP 程序

    Cluster-2# isi_for_array -s ps -auxww | grep -i mcp | grep -v grep
