I have a Dell PowerEdge 2950 with an integrated Raid Controller. The raid will fail as soon as anything is tried with the drives.
Here are the details.
This is an older unit (10 yr) and it is not a production server. It is only used for IT dept. testing. It was originally configured with 8 73gb drives. It has, and still will run just fine with those drives. They are a mixture or original Dell drives and Seagate (ST973451SS) drives. The Seagate drives are replacement drives from past failures. As I said, everything works well, without and problems when using these drives.
I thought I would expand the drive storage on this to allow VMware ESXi to be used and allow for multiple test machines. Again, when used with the 73gb drives, no problems.
I try exchanging out the drives for 146gb drives, and this is where the problem begins. The drives are Seagate ST91466852SS.
I can put the drives in and boot the server, and get to the Raid controller (Ctrl-R) and the system sees the drives and lets me set up a Raid configuration. (0, 1, 5) I have tried them all.
Tipically I would set it up as drive 0 and 1 in Raid 1, and drives 2 thru 7 in Raid 5. But I have tried different scenarios and they all react the same.
It will let me initialize the drives after creating them. All is still well at this point. I can reboot the server and all is still OK.
As soon as I tried to install and operating system, whether a Server, Windows OS or VMware, the Raid fails. The install process sees the drive long enough for me to start the install, then the Raid fails. I can go into the Raid Controller again and the Raid Virtual drive for the one I was trying to install on, is gone.
I have tried installing the current version of the Raid Controller Firmware (5.2.1-0067) but it still acts the same.
If it is important, the BIOS version is 2.7.0
The Raid is PERC 5/I
I can insert two of the original drives (73gb) back into the machine, go into the Controller, set everything back up with the two drives on Raid 1 and the other (146gb) drives on Raid 5 and it will be all good all the way thru the install of any OS. As soon as I try to do anything with the 146gb drive setup, the Raid for those drives will fail. The OS running on the 73gb drives will remain stable, just the 146gb drives fail.
Yes, I know these are not the "Dell" preferred drives. I guess I was just trying to be a little cost conscience since this server was not a production system.
I have searched the internet and tried several different things, but I have never found anything that would lead me in the right direction.
Maybe I will just have to break down and Dell drives. A little harder to find for a 10 year old machine.
Thanks for any help
