In particular, you're talking about IDE RAID, which is not fully supported in Linux, although the HPT370 is supposed to be pretty good. Hardware RAIDing is done by the chipset, but a driver is required to communicate correctly between the OS and the logical drive created. The quality of the driver should really only effect bits of available hardware functionality. If you add the modules disk with the driver on during setup, and then you only see one hard drive, it's working. If you still see two separate drives, it's not...

I've a HPT 370 RAID controller here (ata/100) and a pair of matched 40gb disks which I want to raid 1 (mirroring) for a server. Where is the raid'ing done? In the card hardware? By the operting system? By a combination of both? The HPT bios option (ctrl-h on bootup) gives the option to set up raid 1 and to start the raid. But it also seems I have to install the driver, and in one of the howto's someone mentioned that in some cards a lot of the functionality of the raid was handled by the driver... So what does what? If one just sets the card off it will, I assume, light up the disk lights like a xmas tree as the second disk is mirrored...? But if the driver isn't installed does this mean it won't raid, only one disk will be seen, will only work at standard ide speeds - or what? Further, does anyone know if the more recent hpt 370 raid driver works with SMP kernels? The original one for suse 6.4 and 7.1 specifically said it would only work with uniprocessor, but there is no mention either way in the more recent 7.3 release. -- To unsubscribe, e-mail: suse-linux-uk-schools-unsubscribe@suse.com For additional commands, e-mail: suse-linux-uk-schools-help@suse.com
