ITE 8212 Raid management


I've have installed on my computer an ITE 8212 raid controller with two discs. Following the instructions on these forums, I have installed a Debian Sarge 3.1 with kernel 2.6.11 (with ac7 alan patches) and now all seems to be ok. My raid controller is configured as RAID 1 (mirror).

And now,

How can I know that all is working ok?
Is there any software to manage this raid controller on linux? I would like to know if both discs are working!

Thanks for all

You have to use dmraid to look up meta information that software RAID controller has stored. It is better that you use Linux software RAID instead that comes with the controller.

You should use kernel >=2.6.12 because it fixes a lot of problems (mostly security problems) that 2.6.11 has and it includes ITE 8212 with out the need of patches.

Im a bit confused

As I told you in my previous post I had an ITE 8212 pci ataraid card. Im a bit confused. This is a hardware raid, isn't it? I have been reading some information about dmraid (as you commented in your post). This text is extracted from dmraid's README:

...
This software discovers, activates, deactivates and displays properties
of software RAID sets (eg, ATARAID) and contained DOS partitions.

The following ATARAID types are supported:

Highpoint HPT37X
Highpoint HPT45X
Intel Software RAID
LSI Logic MegaRAID
NVidia NForce
Promise FastTrack
Silicon Image Medley
VIA Software RAID

...

Perhaps my question sounds a bit stupid but, whats the difference using one of these cards instead of one as described here: http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html

I thought that these chipsets were (as mine) hardware raid controllers, not software. Can anybody explain me if these type of chipsets are hardware raid controllers or just only ATA interfaces?

Thanks for all

It is a software RAID controller. It is not a hardware RAID controller. An example of hardware RAID controller is any 3ware models. A hardware RAID controller contains the storage controller chip, processor, and RAM. This card should not be confused with on-board RAID controllers which are software RAID that uses the main processor and main memory to handle the transactions. You will have to use dmraid for your controller. The utility dmraid probably will not work for your controller. If there is no data on the drives, I suggest deleting the array and use Linux software RAID instead. Linux has good utilities to manage its software RAID arrays.
