Operating system is recognizing only one hard disk.

Hi,

I have installed windows 2003 server on IBM x345. It has 2 73GB hard drives. But the Operating system is recognizing only one hard disk.

Please suggest.
Thanks & Regards,

Shekar,

Could you able to see the IInd disk in the Disk Management?
I am not sure whether you have partitioned the IInd disk. If it appeared as unallocated space, you can partition it.

According to http://www-132.ibm.com/webapp/wcs/stores/servlet/CategoryDisplay?categoryId=2559453&storeId=1&catalogId=-840&langId=-1 the x345 has an integrated RAID-1 controller.

Most probably RAID-1 is activated and your disks are being mirrored, so it's perfectly fine you only see one disk.

If you have not installed the IBM ServeRAID utility, download it now and install. Then, for the RAID configuration. You will need to reboot your server after you install the ServeRAID utility.

Hi,

I donot want mirroring to happen. Instead I want to use the 2nd hard disk for data storage.

Is there a way to disable mirroring and use the 2nd hard disk for data storage?

Please suggest.

Thanks & Regards,

Gnana:

Found a great link for the x-series servers over at IBM. Maybe one of their experts can give you a hand:

To disable RAID-1, you will need to reboot the server and enter the RAID-controller BIOS (the key you have to press will be shown when you reboot the server, I think it's F8). Once there, you'll be given the option to disable RAID-1.

Your server is able to perform RAID-1 (mirroring disks) and RAID-0 (no mirroring, you'll have both disks avaible to store data).

The problem is you will need to reinstall the operating system when you disable RAID-1. Boths hard disks will be reformatted.
