I bought a new Dell PowerEdge Server but cannot identify the second drive. I will like to find out if RAID is already running or is a problem with configuration.
Typically it is preconfigured at the factory. To find it reboot the server, and when it is posting look for the RAID card access key instructions. Brian, is open manage now working on the entry level Dells? If it is this is good news and another great thing about Spiceworks. Owen, I can't say either way specifically. The only way to know for sure is to install latest openmanage and see if it is recognised.
I found this to be a real pain for managing small sites as there seems to be no way of knowing if the raid array has failed remotely.

I beleive you get a local alarm from the box via a beeping and status lights. Personally I dont support anyhting without DRAC enteprise which gives snmp monitoring of the disk array plus graphical console redirection but some may not be so lucky.
Kyei, did you see this option during POST? Did you get into the RAID controller? And which RAID controller did you get? I have two Ts and this works fine on one but the second server absolutely refuses to boot to the RAID card properly. I even replaced the card thinking the first was defective. I have no idea what the issue is yet and am banging my head against the wall.

In the following example, 4 disk drives are online and already configured. For e. A indicates logical volume 1 and disk 0. A indicates logical volume 2 and disk 1.
Press F10 to continue the configuration of two selected disk drives. This will display the Array configuration screen as shown below. The array number A02 number that got assigned for the new disk drives from the previous step, is displayed here. The advanced menu in the above screen has the following options. After saving the configuration, reboot the system. Very useful information. Thought, you are talking about the server config, I guess the process will be applicable to high end desktops as well?
This is a great post inded. I will book mark it for sure. I have configured the Raid in Windows. Even the Raid 1 is the best for mirroring data. Last year I was In a situation were I wanted to backup all my data as my pc was crashing most of the time. So I thought to configure the raid 1, but when later I come to know that its always feasible if you setup a NAS box. There are many reason I go for the NAS. I had 4 pcs in my home network and I can keep the NAS as a central backup point.
Please be aware there is now a new RAID bios that comes with dell adaptors look a bit different but essentially does the same job. The user interface has three screens or tabs if you want to think of them that way. And a third that shows controller details—and from which you can upgrade the controller firmware. This is a wonderful post and just what I needed and was searching for.
These drives are partitioned in the standard C, D configuration with the large D partition containing an expanding searchable database. After installing two new RAID 1 drives with the help of this post, can I extend the D Partition on the original drives to include the new drives?
Any comments or suggestions will be very much appreciated. I see no mention of formatting in the original post or follow up comments. Do the new disks have to be formatted, or is that done after that are attached in the RAID configuration?
Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up. These discs are running in RAID-1 configuration, either 1 or 2 virtual discsand on top of this, we have the C and D drives. As we are running low on disc space, we are looking at dropping the RAID to get some disc space back. Is it possible to split the discs back into 2 seperate hards discs that the OS can see, without losing all the data on the drives?
You can't break the RAID array without losing the data. If I'm not mistaken you can set the raid controller from RAID mode to SCSI mode which will leave you with two independent disks, but you'll lose the data in the process.
Also, what kind of data do you have? Since every disk can work independently you could use one of the disk for the C: and D: and mount the other disk in E: Of course you 'll have no redundancy. After reconfigure RAID, you have another problem: the s. Windows must see and use the "new" space available. But if your local disks are Basic Disks, its more complicated.

Assume the scenario where the server came with 2 physical hard drives configured in RAID This Logical Volume is where the operating system is installed and you got a request to expand disk space on this server. So, you have purchased additional disks and would like to configure a RAID setup. First, insert all new disks in the empty slots. If there are already disks on slot 0 and slot 1, start inserting the new disks from slot 2.
In this example, the new 4 disks are inserted from slot-2 to slot After the disks are inserted, reboot the server. Press Ctrl-R when it is displaying the following message on the console. This utility will have the following three TABs on the top.
This will display a pop-up menu with following choices. Following are the various sections displayed in this screen:. This section will display all available disks that are not configured yet. Every physical disks will display Drive ID and Size. Press space bar to select the disks.
Keep pressing space bar until all available physical disks are selected as shown below.
This total size is calculated and displayed automatically in the VD Size under basic settings. You can also assign a name to the VD. Click OK to continue. Warning Message: It is recommended that all newly created logical drives be initialized unless you are attempting to recreate a previous configuration and recover data as initialization is a destructive process.
Use arrow key and highlight the Virtual Disk 1, which will display the following properties of both Virtual Disk and Disk Group on the right side.

What a coincident! Andrew, Yep. I really like the new RAID conrollers on Dell servers, as they have the RAID-5, which I think is an better option without sacrificing the fail-over capability, as if one drive fails, your data is still not lost. How did it go? I found this post when experimenting with a new Dell PE T It has 4 hard drives.
I then am trying to expand the array to 4 active drives. Is that doable? Adding a 4th drive to an array and have it expand say each is GB.How the BIOS set up needs to be setup in doing this?
I have small business and i am not familiar much with RAID setup, but more comfortable with traditional way if using Sata, backup and cloning. It is not really important if the server goes down for half a day or so. With the RAID controller in place you can use single disks although not recommendedyou still need to create a logical volume in the RAID utility consisting of your single disk.
I would also take the time to learn RAID as it is an almost essential tool in many systems these days. Thanks Rod-IT! I have a bit of understanding of RAID and its advantages, but still want to get away from it as technology and prices are change big time. You do not have to have aRAID to keep the business going or not worry about backups.
I am more comfortable this way. Nowadays virtualization is hot and easy to maintain.Why You Should NOT Use RAID 5 Storage ( But Use RAID 6! )
Do i have to change the Bios setting before or prior? How would you migrate the OS windows server R exists in on partition with all its setupsI an thinking about cloninig it usinf Acronis or Clonzilla BUT again i want to make sure i do not screwup things. With windows server i am new and decided to keep it instead iof switching it to LINUX or Mac since one software runs only on windows at least for now Any insights would help to keep what is running for a year or two.
The systme is extremely slow and it was passed onto me and i think the perc and raid setuo never setuo oriperly. You should or will likely still use some type of RAID as the guest storage as you don't want guests failing when a disk does. To use it how I mentioned, leave the controller in, when you boot the machine choose to edit controller settings and create your disk - a partition if you will and make it logical, that's it.
The server is running as we speak. How would I know if uses Hyper? It has hot swappable bay and two of them has gb of HD each so I assume two guests. You have 2 disks which are obviously configured as a mirrored pair, why would you want to change this for a single SSD? Am i going to ctrl-s or ctrl-c? I can always use usb optical drive if needed. The H is a miserable excuse of a raid controller when compared to the H, but when compared to no raid Modern backup and recovery tools are largely dependent on virtualzation.
Some will work physical machines but there are often more quirks. Host access will be very important here. And you get the risk of complete failure.Recently I noticed that the Dell OpenManage software is showing one of the drives' state as "removed".
Assuming that the drive is bad and that this is not simply a case of a loose cable, what's the proper procedure for replacing the "removed" drive with a new one?
My understanding is that if the drive state was "failed" then I could just pull it, replace with a new one, and the controller would rebuild the new drive automatically, correct? But since the drive is listed as "removed"--not "failed"--will that still work or is there a different procedure I need to follow? I do have a full backup of this server including the system state and I'm prepared to do a bare-metal recovery if necessary hopefully not! I don't have a T, but it sounds like it the drive cannot be seen by the controller.
It may be the cable or the drive may have come unseated, or the drive has failed so totally it can't be seen. If it does, it will have to rebuild the array.
IMHO, it's safer to replace the drive and then troubleshoot the old drive somewhere else, than it is to "take a chance" on the old drive.
I would blink the lights 'identify' to make sure I knew what was what. Try reseating first, if it works may show 'rebuilding' otherwise just pop it out and put in a replacement. Should all be automatic but you can check the status in the openmanage to see if it is actually rebuilding. The controller thinks that the drive has been pulled. That might be a carrier issue, or perhaps an electrical connection has become oxidized that old trope.
Re-seating is the first thing to try. If that fixes things, it will almost certainly have to re-copy the current drive state. Just monitor closely to make sure there isn't some hardware level connection going slowly bad. Definitely reseat it. It is a mirror so there isn't risk with this like there would be with parity RAID.
To the device, it believes that you have already removed the drive, so you are a full stage past the "failed" point.Page of 56 Go. PowerEdge T Technical Guidebook. Table of Contents. Dell 8 Installation Manual 70 pages. Information update - system setup program 14 pages.
