Overview

On a Dell PowerEdge 2950 with Perc5i Raid card, we want to know Raid status. So we install software to check it manually with system Online.

Software installation

We download MegaCLI software. This software is difficult to find, and we only found a version for RedHat.

Package is an rpm not a debian or ubuntu compatible package. So we transform it using alien command:

# apt install alien
# alien MegaCli-8.07.14-1.noarch.rpm

And we install it:

root@nas:~/Linux# dpkg -i megacli_8.07.14-2_all.deb

Execution

The program MegaCli is installed, so we can use it with command:
