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:

..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 don't see them when i run fdisk -l:

server1:/dev # fdisk -l

Disk /dev/cciss/c0d0: 73.3 GB, 73372631040 bytes
255 heads, 63 sectors/track, 8920 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0002df0f

Device Boot Start End Blocks Id System
/dev/cciss/c0d0p1 1 262 2104483+ 82 Linux swap / Solaris

server1:/dev #

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?

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
