Symptoms

PowerPath/Linux 主机无法连接到 PowerPath Management Appliance （PPMA），因为 PowerPath Management 服务无法根据错误启动：

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

这是因为 Linux 主机上未安装 libjson-c.so.2 库。

 

提醒：在 Red Hat Enterprise Linux 7.5 中，json-c 在最小安装中默认未安装，建议单独安装软件包。

 

Resolution

建议单独安装 json-c 库并启动 PowerPath 管理服务，在这之后，PowerPath/Linux 主机可以添加到 PPMA。

 

Additional Information

这也记录在 PowerPath 文档中。
