Question about IBM ServeRAID-7k Controller (71p8642) SCSI Controller

1 Answer

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 drives to upgrade the existing 73GB HDs. What's the best possible way to upgrade these hard drives without a chance of loosing data or needing to reinstall everything? Please help !!

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.

I have a server with a Serveraid 4H controller card, set up with two Arrays. Array B has 3 72GB drives set up as RAID 5. I would like to add 2 more drives to this array. Is this possible or do I have to...


I am not familiar with your RAID controller card but as long as the controller can see two additional drives, it shouldn't be difficult to add two new drives to your exisiting RAID 5 configuration.

You will probably need to reinitialize the RAID configuration for discs to copy all the parity information so you should refer to the documentation on re-initializing the RAID.

I was running 2 scsi drives in a raid 0. One drive failed, how can i retrieve the files off the the still working drive, and can i?


Hi there, Sorry to break the bad news, but when one hard drive fails in a RAID 0 configuration, all data is lost. Your only chance is to take it to a professional data recovery center, where you could be charged hundreds, or thousands of dollars for a data restore. Seagate will do these recoveries for you. RAID 0 has no redundancy, unfortunately. Sorry about that, Alex
