fdisk -l

Disk /dev/cciss/c0d0: 734.0 GB, 734054703104 bytes
255 heads, 63 sectors/track, 89243 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/cciss/c0d0p1 * 1 13 104391 83 Linux
/dev/cciss/c0d0p2 14 89243 716739975 8e Linux LVM

Re: How to find HARDWARE RAID Details

Hi,

Are you using local hardware or shared storage? AFAIK there are some utilities available from storage vendors (like HP's XP series) which lets you see the storage device details.

Also, if you are using VMWare you probably will not be able to see the device details because it may be translated by Host Operating system. In that case you will have to look at the VMWare console.

I am sure not helping you much but thinking my 2 cents worth...

Re: How to find HARDWARE RAID Details

sorry forgot to mention that HP's utility to see the XP RAID detail is called XPINFO.

Re: How to find HARDWARE RAID Details

Hi,

Those device names show that you're using SmartArray controllers of some form.

If you haven't got the managment tools installed, hpacucli, then you can look in the special /proc files to determine the RAID level. Something like:

# cat /proc/driver/cciss/cciss0

Cheers,
