First of thanks for the fast replies!
I should probably clarify what I am doing an how I know I have a problem:
I take different machines with the same configuration, same type RAID card connecting 8 HDDs of the same type. The machines are supposedly identical. I run a "dd" command and I have a standard benchmark that I know I am supposed to hit. If any particular is slower then the benchmark I need to find the problem, and my first thought is that one of the HDDs has a problem (i.e. bad sectors). The problem is that currently I have no way to test each HDD individually (what I end up doing right now is taking out each HDD by its own, connecting it to another PC with Ubuntu and running "SMART Disk Test" on it), then connecting them all back to the machine with RAID and logically reconstruct the RAID again).
I was wondering if there was a way within Red Hat to do something similar to the Ubuntu "SMART Disk Check" that preferably can also do it without disassembling the RAID logically.
I am using RAID 6 on 8 HDDs.
When using "lspci -v" command I get for my RAID controller card:
anchele I am not sure what you mean by how the RAID is configured, if there is anything else you need me to tell you I would be glad to, but as I am new to this I might need some explanations on how to acquire the information.

Hi,
We have a Sunfire 4150 with On-Board Internal Raid Controller connected to 4 X 146 GB SAS disks.
This also has an External Raid Controller (Storagetek Eight-Port, External HBA
Model SG-XPCIESAS-R-EXT-Z) connected to a JBOD array ( Storagetek XTA2530 ) which has 5 X 300 GB Hard disk.

asr
ASR(4) BSD Kernel Interfaces Manual ASR(4)NAME
asr -- driver for Adaptec I2O based SCSI/ATA host bus adapters
SYNOPSIS
device asr
DESCRIPTION
The Adaptec asr driver provides access to disks and disk arrays controlled by I2O based host bus adapters and SmartRAID SCSI RAID adapters
through the standard SCSI disk da(4) interface.
The supported adapters provide 64 bit PCI, Compact PCI, Zero Channel PCI, and up to four channels of Ultra2, Ultra 160, or Ultra320 SCSI, or
two channels of 1GB Fibre. All support RAID-0, RAID-1, RAID-10, RAID-5 and RAID-50 arrays. All SCSI target types are supported. For the
ATA based controllers, one IDE drive per channel is supported. Hot-swapping of IDE drives is not supported at this time.
All host bus adapters must be configured before they can be used with any operating system. Please contact Adaptec directly to obtain the
latest information on configuration utilities for the adapters. Currently there are both a Motif based GUI configuration utility and a CLI
based configuration utility available from the Adaptec Web site. The cards and arrays can also be configured via the BIOS based configura-
tion tool (SMOR).
HARDWARE
The adapters currently supported by the asr driver include the following:
o Adaptec Zero-Channel SCSI RAID 2000S, 2005S, 2010S, 2015S
o Adaptec SCSI RAID 2100S, 2110S
o Adaptec ATA-100 RAID 2400A
o Adaptec SCSI RAID 3200S, 3210S
o Adaptec SCSI RAID 3400S, 3410S
o Adaptec SmartRAID PM1554
o Adaptec SmartRAID PM1564
o Adaptec SmartRAID PM2554
o Adaptec SmartRAID PM2564
o Adaptec SmartRAID PM2664
o Adaptec SmartRAID PM2754
o Adaptec SmartRAID PM2865
o Adaptec SmartRAID PM3754
o Adaptec SmartRAID PM3755U2B / SmartRAID V Millennium
o Adaptec SmartRAID PM3757
o DEC KZPCC-AC (LVD 1-ch, 4MB or 16MB cache), DEC KZPCC-CE (LVD 3-ch, 64MB cache), DEC KZPCC-XC (LVD 1-ch, 16MB cache), DEC KZPCC-XE (LVD
3-ch, 64MB cache) -- rebadged SmartRAID V Millennium

NOTES
The ATA based controllers present their devices as SCSI-like devices via CAM. For IDE drives attached to these cards, a subset of standard
SCSI commands and mode pages are understood via translation performed in the card's firmware.
SEE ALSO da(4)HISTORY
The asr (Adaptec SCSI RAID) driver first appeared as the dpti2o driver under BSDi BSD/OS 3.2, then under FreeBSD 2.2.8 and was ported over to
the CAM layer represented in 4.0.
