Dear All
I would Like to know that if suppose c1t0d0 is of 72 gb hard disk and system boot from this hard disk and c1t1d0 is of 147gb hard disk. Can we implement hardware raid (Mirror) between these two hard disks of different capacity if raid crontroller is present in the server
Kind regards (4 Replies)
Hello all
We've just bought a T2000. It has two disks and I'm trying to figure out how to create a mirror of the boot disk. I understand that I have to boot into single user mode from DVD and then use the raidctl command to set up the mirror and label the volume afterwards.

I setup a RAID 5 with 5 drives, one failed, hardware failure so I physically removed it from the raid after powering the machine off then powered it back on and my raid was still good but no 5th drive. I built a 5th drive from scratch and added it in the raid thinking the raid would go into... (0 Replies)

Hi All,
Quick question on the RAID. I have a Dell server with 27 hard drives. Two hard ware controller cards. Boot disks will be mirrored. That leaves us with 25 disks. I need to configure that as Raid 5. On the Boot disk, already installed RHEL 6. How do I make the 25 disks as RAID 5?

ATARAID(4) BSD Kernel Interfaces Manual ATARAID(4)NAME
ataraid -- software BIOS RAID
SYNOPSIS
pseudo-device ataraid
ld* at ataraid? vendtype ? unit ?
DESCRIPTION
The ataraid driver provides support for BIOS-based software RAID controllers. These are devices which have some simple support for several
basic RAID levels (often RAID 0 and RAID 1), but which require software support to actually perform the RAID function. The BIOS support is
largely just to create and recognize the array so that it may be a boot device.
The driver currently supports RAID formats from:
o Adaptec HostRAID (found in Intel 6300ESB)
o Intel MatrixRAID
o JMicron RAID
o nVidia MediaShield
o Promise FastTrak
o Via V-RAID (found in many VIA-based motherboards)
Status of the logical disk as well as the disks associated with it, can be viewed through the bioctl(8) utility.
SEE ALSO ld(4), bioctl(8)HISTORY
The ataraid driver first appeared in NetBSD 2.0.
AUTHORS
The ataraid driver was originally adapted from FreeBSD by Jason Thorpe <thorpej@NetBSD.org>.
BUGS
Not all features of the software RAID are currently recognized or supported. For example, the Adaptec support doesn't recognize when a RAID
1 should be in a ``building'' state, and it does not do the right thing.
At least part of the reason for this is that the publically-available information on these formats is quite limited.
