Linux Installation

Hi,

I have Server connected with RAID disk array. Now i would like to install linux pn RAID partition and boot from RAID partition.

I could install the linux on RAID partition but how do i boot from RAID partition on which linux is installed.

When i check the boot order in System BIOS, i only find local HDD.

Is there any solution for this problem??

Re: Linux Installation

It depends of the server BIOS, but there is always an option to boot from the SCSI disk. If you cannot find it on the server BIOS itself, you can find it in the RAID adapter BIOS. There are key combinations to enter the raid adapter bios, like ctrl+a, normally prompted during server boot.

Re: Linux Installation

Hi,

Normally u will be getting option to go in to the scsi bios menu by pressing CTRL+A or Ctrl+M at the time booting.Then u can configure ur scsi hdd s a BOOT device.
If the OS is already installed on raid device but not booting..the problem can be in two ways..1) BIOS Setting has to change.(Or)
2) U have to install the boot loader manually thru rescue mode..

Re: Linux Installation

Hi,

It sounds like you might have installed the Boot Loader on a different disk to that where you installed the OS.

You don't mention which version of Linux you're trying to install, but I know with Red Hat 3 this has caught me out a few times.

The installation program finds all the disks correctly and you install the OS onto the RAID partition that you want, say /dev/sda. However by default GRUB installs onto the first disk found in the server, say /dev/hda so after the installation you can't boot.

If you're still having problems let us know what version of Linux you're trying to load, and what server you've got.

Hope this helps,

Regards,

Rob
