1. First get the latest version of MegaCLI from LSI website (choose MegaCLI - Linux from the list). Unzip the downloaded file. The package inside the .zip file is an .rpm so it needs to be converted into something more useful. 2. install alien, convert the .rpm into a .tgz and ‘untargzip’ it : $ sudo apt-get install alien $ sudo alien –to-tgz MegaCli-1.01.39-0.i386.rpm $ tar xvfz MegaCli-1.01.39
