Symptoms

PowerPath Linux 主機無法連線至 PowerPath Management Appliance (PPMA),因為 PowerPath Management 服務無法根據下列錯誤啟動:

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

這是由於 libjson-c.so.2 未在 Linux 主機上安裝的程式庫。

在 Red Hat Enterprise Linux 7.5 中, json-c 在最小安裝中預設未安裝,建議單獨安裝包。

Resolution

建議安裝 json-c 當 PowerPath Linux 主機可新增至 PPMA 時,請個別建立程式庫,然後啟動 PowerPath Management 服務。

Additional Information

PowerPath 說明文件中也會記錄這一點。
