megaclisas-status

This will perform health checks on a MegaRAID device using the proper binary for your platform.

Debian information on the binaries are here: http://hwraid.le-vert.net/wiki/DebianPackages (Note that the megaclisas-status linked here is the original un-maintaned version and not this fork).

MegaCLI previously offered by LSI is now maintained by Broadcom, a package with combined binaries for all operating systems can be found here: https://www.broadcom.com/support/download-search/?dk=megacli

Note that the MegaCLI package is only available as an RPM so you will need to use alien or equivalent to convert to your distributions preferred packaging format.

Usage

• no parameters: show megaraid info
• --nagios: show nagios-friendly output
