Talking Help with new hard drive configuration


Folks;
I just added 2 physical new hard drives to my SUSE server. My server is already running SUSE 10.3 version.
Is there a command i can use to add the new space or even see if the system can sees them?

You can use:

Code:
# fdisk -l
..to see if the hardware is recognised and the labels (eg. /dev/sda3)
and then mount them somewhere so that you could access them. Afterwards you could add specific entries to /etc/fstab to make it mount automatically at the boot

edit: post the output of fdisk -l and we can help you mount them.

I've never used RAID, but I would assume that fdisk should show all the physical hard drives that are connected to the computer. Have you checked the cables?

Code:
find  /dev/ -maxdepth 1|grep [sh]d
This will show all device nodes that are used for disks in the machine and their partitions.

If it's HP HW raid (& I think that nomenclature implies it is) then the RAID controller handles it invisibly.
You can try running

df -h

and see if its more diskspace than you used to have.
There should be a way to ask the controller about what it can see (serial console?)

thats cool. I've never worked with hardware raid before. But I guess it makes sense that the device would look differently to the cpu in a hardware raid configuration...

Thanks folks;
i found out since this is RAID, i must configure the RAID before the physical drives can be seen by the system. once i created the RAID, i was able to see the new drives
