MegaCli

Latest revision as of 18:47, 18 March 2010

MegaCli is LSI's command line interface to their MegaRAID controller family. Dell uses them in their servers as e.g. "PERC5/i" or similar. Our dataset1 server uses this RAID controller.

The tool can be downloaded from the LSI website, e.g. here Version 8.0. The ZIP file contains a ZIP file which contains two RPM files.

[edit] Installation from the ZIP file

apt-get install unzip
wget http://www.lsi.com/DistributionSystem/AssetDocument/8.00.11_Linux_MegaCLI.zip 
unzip  8.00.11_Linux_MegaCLI.zip  MegaCliLin.zip
unzip  MegaCliLin.zip MegaCli-8.00.11-1.i386.rpm

apt-get install rpm
cd /
rpm2cpio ~-/MegaCli-8.00.11-1.i386.rpm | cpio -div
apt-get install libsysfs2
ln -s /opt/MegaRAID/MegaCli/MegaCli64 /usr/sbin/MegaCli

[edit] Common Parameters

Many of the commands of MegaCli make use of the following parameters:

-aN

Specifies the adapter. Use -a0 for the first adapter, -a1 for the second, or -aALL for all adapters.

-PhysDrv [E:S]

Specifies a physical drive. E is the enclosure ID, as returned by MegaCli -EncInfo -aALL. For dataset1, the possible enclosure IDs are 16 and 41. If more than one drive has to be specified, the drives are written in the form [E:S, E:S, ...].

-Lx

Specifies a virtual drive (aka RAID array) (where x is a number starting with zero or the string all).

[edit] Monitoring

The following commands can be used to check the status of the arrays.
