The Dell PowerEdge S100 and S300 systems use a software RAID driver called the dmraid (Device Mapper RAID) driver to manage software RAID arrays. The dmraid driver is a Linux kernel module that provides support for various hardware RAID devices, including those used on the Dell PowerEdge S100 and S300 systems.
To install the dmraid driver on a Linux system, you will need to install the dmraid package. The dmraid package is available in the default repositories of most Linux distributions.
For example, on a Debian or Ubuntu system, you can install the dmraid package using the apt-get command:
$ sudo apt-get install dmraid
On a CentOS or Red Hat system, you can install the dmraid package using the yum command:
$ sudo yum install dmraid
Once the dmraid package is installed, you can use the dmraid command to manage your software RAID arrays. For example, to list the available RAID devices, you can use the following command:
$ sudo dmraid -s
For more information on using the dmraid driver and the dmraid command, you can refer to the dmraid man page by running man dmraid on the command line. You can also refer to the documentation for your Linux distribution for more information on configuring and managing software RAID arrays.
