    What type of RAID controller are you using. For most controllers, when you replace a drive, you have to go into the controller's interface and set the drive up.

How to save a raid0 disk


Raid O is no RAID. Data is lost if the hard drive failed. Always use RAID 1 (mirrored) for OS and RAID 5 (striped) for DATA. That's 5 drives your server should shave been configured with.

FAIL-SAFE FILE SERVER AND COMPUTER SYSTEMS

If your data is very important, you should consider doing regular data backups because hard disk will fail at some at some stage in the future. This is especially true when you get an error message"hard drive is about to fail".

Depending upon how critical your computer or files server to you or your business, you should consider building a fail-safe computer or file server system using RAID technology. RAID means "A Redundant Array of Inexpensive Disks" and there are several levels of RAID.

For details of different RAID levels - click on this link -
http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci214332,00.html

The most common of the fault redundant RAID systems are -

RAID 0 + RAID 1 provides fastest data transfer Mirrored hard drives.

RAID 5 is one of the most popular system, it data striping across hard drives with error correction. It has excellent performance with fail-safe system and allows for hot swappable hard drives.

There should be redundant powers supply inside the computer or file server in the event of a power supply failing.
Another consideration is to install a UPS (uninterruptible power supply) to prevent a computer or server shut down from power outages, as this will corrupt your data.

These systems do not mean you should not back up your data on a regular basis.

I have a Gateway Server model 9210 Raid 5 (3 drives) Small Bus. Server 2003 and one drive failed. I purchased the same dive. Do i just shut down the server and replace the bad drive or do i hv to go into...


Hello,

With a RAID 5 setup, if you replace the drive with the exact model, you only need to shut down the server, replace the drive, power on, and the RAID will remount the new drive to the needed confiuration.

Good Luck.

Dell poweredge t110 Raid 5 setup on PERC 100 raid config in bios stating Virtual drive degraded and drive 2 is in ready state...how do we remove from drive array and install a new on without data loss


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.

PERC 3Di one drive is failed how do I remove and replace without losing the container?


Replacing the drive does not remove the container on the RAID controller. If the drive has failed, and you had a RAID 5, simply replace the drive. If you had a RAID 0, your data is lost. Replace the drive, and start over.

About SCSI


Replace the hard drive with a drive that is the same type and the same size, or larger. It will rebuild itself.

By same type I mean that the connector on the back of the drive and the speed of the drive interface must be the same. If the new drive spins at a different rate it will not create a problem, except that if it is slower it will make read/writes slower. If it is larger it will only use part of its capacity, matching the capacity of the other drives.

Note that if you were to replace all drives with larger drives (one at a time) the capacity of the entire array would be the same as the original. If you want a larger array it must be built from the start with that larger capacity.

Take out the bad drive. If you can get the exact same drive, do it, otherwise look it up on the manufacturers web site to find out size and type.

While there are a few possible RAID configurations that you could be using on that server, the chances are overwhelming that it is RAID level 5 that you are using. This RAID level is tolerant of a single drive failure. If you lose another drive before your new drive rebuilds your data will be lost. Hopefully you have a backup.

RAID 5 stripes the data and the parity data across all available drives and when a drive fails, the missing data is rebuilt on the fly from the parity data. When a replacement drive is installed the parity data is used to rebuild the data that belongs on that drive. The advantages of RAID 5 are fault tolerance (of a single drive) and speed because each drive only has to provide or write its portion of the total data being accessed or written.
