In a RAID 5 config, you need at least 3 drives (you can have more however). A small part of every drive is then reserved for recovery data for the other drives. So two drives together hold all the data needed to restore a 3rd drive.

The Raid Controllers in the Dell Poweredge Servers are hot swappable. So you can just pull the faulty disk and then insert a new replacement drive in the same slot (Needs to be the same type and size or bigger. However, if the disk is bigger than the other 2, then only the size of the two other disks will be used on the new drive). The Raid controller will then see that there is a new disk and automatically start the recovery process. You will be able to see this when you open the Controller software. Once the recovery is done, the RAID 5 will be fully functional again.

While one of the disks is faulty or missing the two remaining disks will continue to work, but at the severely degraded performance. After the rebuild the performance will be back to the way it was before.

The rebuild can take more than an hour, depending on the disk sizes used.

There is also an option on some Controllers to select one drive as a "spare". Then you insert one more disk and set it as spare. It will not start working unless one of the other disks in the Raid fails. That's when it is used automatically as a replacement.

A disk read error has occurred when booting a Dell PowerEdge 2950. Passes all diagnostics. Will run chkdsk from CD. Raid battery was degraded at last reboot but all disks showed to be fine. Raid 1

what OS?
what disk?
no raid card stated, no array stated, no type of array stated.
One can put 100s of RAID cards in this server.
both raid cards or HBA cards,(forJBOD)
i can fix any server, but first need to know what is in the box first
you meant the boot disk has errors, right,? boot.
that would tell me the disk IS BAD.
but if and ARRAY , that means you must run SMART tests
on the disks, 1 by 1 to find the bad disk.
if smart shows its bad, or weak its for sure BAD.
on real servers. the server sends you email, (set up right)
telling you disk 3 in a RAID 6 is bad, replace it now.

are you running hardware or software raid, or HBA or
fake raid cards, (4 classes there.!)

the base system new has.
4 port SAS 5/i integrated SAS controller (no RAID_
and optional, from DELL , news.
Optional PERC 5/i integrated SAS/SATA daughtercard controller with 256MB cache,
PERC 4e/DC, PERC 5/e adapter

or any of 1000s of other aftermarket cards there.
I run LSI 9361s (with MSM appl loaded)
this card will tell you what disk failed every time no kidding.
so will the PERCs setup correctly
the PERCs and my LSI and my HP raids
all have installed monitors for the RAID ,a program that runs full time all the time, and reports errors , many ways,
did you load that first and use it? seems not.
as no mention of SMART at all.
good luck.
Im not sure the names on DELL , MSM like software.
ah its OSA
never run a PERC lacking this APP. or you can not keep the server on line,.

I cannot get the Dell PowerEdge 840 to recongize and of my HDD in the Raid array.. Trying to install the OS but tells my on HDD is detected

Then you need to get into the BIOS of the PERC RAID controller and inspect the state of the physical/logical volumes. Reboot the machine and watch for the prompt after the PERC5/6 RAID controller loads it's BIOS.

Considering this a null issue given the age, though...

I am having a problem with my dell poweredge 1800, it beeping continuous

Assuming this is still an issue...old as it is...

You need to boot the server and press the correct prompt to enter the BIOS of your PERC RAID controller. There you need to manage your physical/logical volumes.

Chances are that either you had a drive failure or the metadata on your RAID volume (JBOD?) was corrupted. This is a common issue with these LSI-based PERC[5-6]i RAID controllers that Dell utilized.

Windows 2000 server fails to load,

Even if the scan says all ok I suspect bad sectors. To confirm try making images of the drives.

If you are able to get good images you can try raid reconstruction software.

If you need help I would suggest http://FreeDataRecovery.us they offer both online data recovery and do-it-yourself data recovery

I have Dell PowerEdge 2550 Server. I want to configure RAID, but I can't reach RAID MENU! I have DELL 2550 Server BOOT CD and Dell OpenMenage Server Assistant V7.2. All of them are running, but I...

RAID menu will either be CTRL-A (if you are using the onboard PERC 3/Di) or CTRL-M (if you are using an addin PERC 3/4). If you are not seeing either of these options, then you may not have it enabled in the BIOS. In the BIOS (F2), go to Integrated Devices and make sure that RAID is Enabled. In order to enable RAID, your server MUST have a RAID key, RAID memory DIMM (different from system memory), and a RAID battery.

Wont boot says array controller wont start and no bios dell power edge 2500 server

Sounds like the RAID controller has failed. I would replace this first as RAID controllers are less expensive than replacing the system board, or the server as a whole.

Suggested: PERC 5i (RAID 0/1/5) or PERC 5iR (RAID 1 or 0 only)

1 logical harddisk degraded, RAID Poweredge

Revert back to original configuration of hdd in your RAID setup. Boot to SCIS BIOS and double check functionality of hard drives. The error is probably telling you that Disk1 is degraded because disk 0 is failing and you removed the wrong hard drive.

Problem with creating array

The Perc RAID controller in a 2600 doesn't support RAID 4.
You can do RAID 0, RAID 1 and RAID 5.

With 3 HDD's your best bet would be a RAID 5.

Mirroring is RAID 1 (which would only use 2 of the drives)

Constant beep on poweredge 840 appears to work alright

Hi

Besides standard beeps codes indicating Processor, CPU, Memory or Systemboard failures,
Dell PERC (PowerEdge Expandable Raid Controller) or SAS Controllers (Serial Attached SCSI) generate beeps to alert failures on the RAID sub-system.

From your description of the issues (when the beeps start), i suggest you check PERC or SAS setup. If you have Dell OpenManage Server Administrator installed, you can log-in and check for more information. Additionally, on the next reboot check the PERC/SAS/CERC boot up for any messages. You may also access the PERC (Ctrl+M), SAS (Ctrl+R) CERC (Ctrl+A) Management Menu for specific failures and attempt a rebuild (assuming you have a redundant RAID Volume).

You can also speak with Dell Support and raise a warranty call if the system has warranty.

Note: PowerEdge 840 would ship with PERC or SAS Controller. PowerEdge 700 will ship with PERC or CERC.
