This script aims to check the server for ;

Hardware and software control for Oracle Solaris and Linux
Solaris root disk health state control (ZFS, SVM, and RAID controls)
Root Filesystem Usage Controls for Oracle Solaris, HP-UX and Linux.

Supported Operating Systems;

Oracle Solaris
Red Hat, Centos, Fedora and other for of Linux
HP-UX

Before running the script on the Linux server be sure that you installed the MCELOG package on the server. If not please first install MCELOG then run the script.
