You can recover RAID data from hard drive with RAID recovery software easily.
Tenorshare Data Recovery Enterprise is a comprehensive data recovery software that supports RAID recovery for RAID 0 and RAID 5. Lost data in RAID 0 and RAID 5 can be deeply scanned and restored immediately. Meanwhile, files and folders in RAID 0 and RAID 5 can be copied to other partitions directly. http://www.any-data-recovery.com/product/datarecoveryenterprise.htm

I have IBM eServer with ServeRaid-7K on board controller and have 3 SCSI 73GB hard drives configured in RAID-5 array. Hard Drives are running critically low on space and I bought 3 300GB scsi Ultra320 hard...


First, buy an external storage device, at least 80GB (although it's currently difficult to find any _smaller_ size!) and make a file-by-file, folder-by-folder, backup of your 73GB of "data".

Second, buy another external storage device, and do a Google-search for "drive image freeware".
Pick one of those applications, and do a "image" backup to this second external storage device.

Third, disconnect the 3 "old" drives, carefully label them, and set them aside.

Fourth, connect the 3 "new" drives, delete the old RAID-5 array definition,
and create a new RAID-5 array definition.

Fifth, do an "image restore" from the second external storage device to the new array.

If you have any problems, all you need to do to "back-out" is to:
* disconnect the "new" drives
* reconnect the "old" drives
* delete the "new" array definition
* redefine the "old" array definition

and you're back to the "old" configuration.

Hi. We have a ML110 server with RAID 5 (4x250gb HD SATA) in a Adaptec 2610SA. The RAID has 2 Arrays (#00 Operating System and #01 Data). We have tried to replace a failed HD and since then the Windows...


Did you make sure that your hard drive has been made into a "dynamic volume" instead to the usual "simple volume"? It has to be "dynamic" before your can put it into a RAID configuration. You will have to use your RAID Controller to create a dynamic volume or to make the hard drive part of a dynamic volume.

Can a raid5 be expanded to include an additional disk on the dac960prl or must the raid be destroyed and re-created?


Hi,

As a rule of thumb, a raid 5 array can be expanded to include additional drives. This is done during the boot process and then going into your RAID controller setup. You would then go into the RAID configuration and add the new drive to the array. This was the simplified explanation but i think you get the idea.

Things to consider,
DO NOT remove the RAID array unless you dont care about losing data.
DO NOT try to add a smaller drive than what is currently part of the array.
When possible, the new drive should be identical to the existing drives, but I have added same size, same speed more than once and it will work.
All of the drives you want as part of the array must be on the same controller.

Hope this helps,
Brian

Not getting a drive letter from Compaq SCSI RAID setup


Did you see any new drives in the disk managemen screen? To get to the disk management, hold window key down and hit 'R', then type diskmgmt.msc and hit enter.

If you do see the drive in the lower half of the screen, you need to initialize the drive either as dynamic disk or basic disk. Then you need to add a new partition and format it.

Good luck.

Problem with new array.


Do you see your new disk in the "Disk Management" window? To get there go to "run", type "compmgmt.msc", then click disk management. If you do see the disks there, then you need to format the disk to a "basic" configuration. If your new disk/volume does not show up there, I would suggest a hard reset on your server whenever possible. I see this issue at times with Windows and newly added storage array logical drives.
