# This script is mostly intend to be used with Xymon and rather for devices unknown to the smartmontools base.
# Based on xymon.com's script: https://www.xymon.com/xymon-cgi/viewconf.sh?smart
# The script will scan all devices compatible with SMART and for each disk, it will: [[[
# * try to guess the expected TYPE (even megaraid,…).
# * display health status.
# * set a "clear" state for incompatible device.
# * display last selftests.
# * set a "error" state if no selftest is recorded.
# * display basic informations.
# * recommend a more advanced SMART script if the disk is known of smartmontools's database (drivedb.h) or redirect to smartmontools's FAQ if not.
# ]]]
# Things the script CAN'T do: [[[
# * ensure a recent selftest was run.
# * compare current value with vendor's one (for failure prediction or error).
# * give detail about errors.
# * Take a look to this more advance script for such features: https://github.com/skazi0/xymon-plugins/blob/master/client/ext/smart
