Symptoms

PowerPath/Linux 主機無法連接至 PowerPath Management Appliance （PPMA），因為 PowerPath Management 服務無法根據錯誤啟動：

Mar 30 12:26:35 ner02or-00471 emcp_mond.sh: /sbin/emcp_mond: error while loading shared libraries: libjson-c.so.2: cannot open shared object file: No such file or directory
Mar 30 12:26:35 ner02or-00471 root: emcp_mond.sh: Error starting PowerPath Management Daemon
Mar 30 12:26:35 ner02or-00471 emcp_mond.sh: Error starting PowerPath Management Daemon

 

Cause

這是因為 Linux 主機上未安裝 libjson-c.so.2 程式庫。

 

注意：在 Red Hat Enterprise Linux 7.5 中，json-c 在最少安裝時預設並未安裝，建議您個別安裝套件。

 

Resolution

建議您個別安裝 json-c 程式庫，並啟動 PowerPath Management 服務 post，以便將 PowerPath/Linux 主機新增至 PPMA。

 

Additional Information

這也會記錄在 PowerPath 說明文件中。
