iRMC – OS Installation, RAID Set-up

  Dedicated Servers

It is assumed that you will use KVM in iRMC primarily to install an operating system on the server and to set up the RAID adapter. This guide will cover both procedures related to our Fujitsu servers.

Booting from a CD/DVD/ISO

The article iRMC – KVM, CD / DVD Connection explains how to remotely connect your own data device or ISO file to the server. In this case, we will first reconnect the installation media and then restart the server. In most cases, just press the Ctrl-Alt-Del button at the top of the KVM window.

During server startup, it is necessary to press the F12 key to select the boot method. A prompt to press appears in the lower left corner of the KVM screen. In the menu that appears, you can then choose from two devices. The first is usually the hard disk and the second is the attached boot media.

We recommend mounting netinstall installation media for a significantly faster installation!

Booting media selection

This way you can boot any CD / DVD with an operating system and perform the installation. During installation, it is important to set the provided IP to eth1 for the RX100 (to eth0 for the RX200).

RAID Set-up

If the server contains a HW RAID adapter, it is possible to start its administration interface during the boot sequence. To do this, press Ctrl+C when prompted on the screen.

A call to access raid management using Ctrl + C

After pressing the key combination, a list of RAID adapters will appear. In it, select the desired controller adapters the arrow keys and press enter.

RAID adapter selection

To work with RAID, select RAID Properties.

RAID adapter properties

If we already have RAID set up, the RAID array management will be displayed. Here you can then add (synchronize) / remove disks and set up Hot Spare. However, for the purposes of this example, we will deal with the creation of a new RAID. Depending on the number of disks, select either IM (2 disks) or IME (2 – 10 disks). We do not recommend the Integrated Stripping variant. It offers a larger final capacity (connection of disks), but if one disk falls, you will lose all data.

RAID array type selection

After selecting IM / IME, a list of disks will appear. Use the space bar to specify whether the disk will be a member of the RAID we are setting. Alternatively, it is also possible to set a Hot Spare disk, which will automatically synchronize with a functional disk if one of the disks fails. In the case of IM, it is even possible to keep existing data on one disk and synchronize the other with it. For a clean installation, set the RAID Disk marking to Yes for the disks you want, and then press C to confirm.

Disk definition for RAID

After defining the RAID, you will get out by pressing Esc twice and selecting Exit.
