Ubuntu Raid controller Perc5i Dell 2950
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 Selecting previously unselected package megacli. (Reading database ... 65802 files and directories currently installed.) Preparing to unpack megacli_8.07.14-2_all.deb ... Unpacking megacli (8.07.14-2) ... Setting up megacli (8.07.14-2) ... Processing triggers for libc-bin (2.19-0ubuntu6.7) ...
Execution
The program MegaCli is installed, so we can use it with command:
