Useful Information Related To HP ProLiant RAID Rebuilds

In this article, I want to share with you some useful information related to HP ProLiant RAID rebuilds. I hope this information will prove very useful for you and you’ll be able to rebuild your Raid 10 without any trouble and complications after thoroughly reading this.

In order to rebuild your RAID array, it is not necessary that all the five hard disks are of the same capacity. For example, if you are using an ML 350 along with the 641 controller and five hard drive of different capacities, that is probably OK. Let’s say you are employing three hard disks of thirty six gigabytes and two drives with seventy two gigabytes. Even if the seventy two gigabyte hard drives are acting as thirty six gigabyte hard disks, you can still rebuild them with thirty six gigabyte ones. From here, you can judge the flexibility of your HP ProLiant RAID rebuild, and if any information will be lost.

Remember that because of the fact that all the drives are in single RAID 10, you can easily rebuild them in order to replace seventy two gigabyte drives with thirty six gigabyte drives. Just assign a hot swap to the disk you want drop in and it will automatically get added to the array. It is very important to note here that you must not pull out the hard disk before the completion of the rebuild. Pull the drive out once rebuild process has been completed, though, and you’re fine.

Causes Of Hard Drive Failures Of Dell

Hard drive failures are most frustrating failures that are experienced in everyday life either at home or at your office. It causes the destruction of data and files containing important information. If you are an owner of Dell servers or computers then it is very important to know about the issues and causes of the failure of servers. You should also have someone to call in case you need data recovery services in an emergency. Mostly, the recovery services are provided by the professionals or the experts at your request.

The reasons for the drive failure vary from physical to logical. It may be fire, accidental deletion of files, viruses, power surges, reconstruction failures, disk formatting and overwrites. If you are aware of all these problems, then it will be easy for you to recover your Dell PowerEdge server. It is highly recommended to properly shut down the server, install an anti-virus system and to avoid physically damaging of the hard drives.

All these are the minor precautionary measures. To avoid file corruption, you need to consult a professional for disk partitioning, clicking hard drives, and to reformat the disk. If all the precautionary measures are followed then there are less chances of damaging the data and servers and you can easily it.

The Manual Sharespace RAID 5 Data Recovery Process
Because the RAID 5 data recovery process requires you to determine the array parameters, you can do it both automatically and manually. If you want to do it manually, you should take your time because manual determination of array parameters with Western Digital Sharespace RAID 5 data recovery will be a time-consuming and a tiresome task that requires special technical knowledge.

The manual data recovery process starts with your efforts to determine the disk order, block or stripe size; the first disk and the start offset. The most tedious part is that you have to do them manually. Make sure you know that RAID 0 and RAID 5 are not essentially identical in all respects. RAID 5 stores the parity data and is a redundant array. With the parity position determined, you should also determine the rotation. Thus, you can get the full configuration parameters of the array.

Determining the parity position should be the step of your Sharespace RAID 5 data recovery process. The two parameters of the parity, the position and the rotation, control the parity placement. In order to figure out the parity position, you need to inspect all array blocks. If you find a particular block that differs from data in terms of appearance, consider that the parity block. From there, it’s easy business!
