Perc 3/DC Drive Failure on Raid5
I have a Perc 3/DC controller every time I set up a RAID 5 array the last drive fails. I am getting an background initialization error in Open Manage when I format the new Logical Drive. Any Help would be great.

Yes this is a new array that is being created. The drives are not hotswaps so there really is no backplane just a standard scsi cable. A new one too, bought it 3 days ago. I have suffled the drives and its always the last drive.
is the cable terminated? do any of the drives have a term enabled jumper set on them?
even though it is a new cable have you tried another one?

The first drive has the term jumper the other two don't. Is that correct? Just got another cable about to try it.
The last drive in the SCSI chain should be terminated.
Should look like this:
SCSI card>drive0>drive1>drive2>

If these are LVD SCSI drives (which I believe they are)the spec says that you cannot terminate on the drive itself.
You need an LVD cable and external terminator.

Does it matter if drive0 is the first or last connected on the scsi cable?
disk 0 should be the first
ASKER
If this is the cab le which is the first one?
0------------1----2----3--
0 connects to the perc 3. Is Connector 1 the first one or connector 4?
hate to be astickler for detail but I have spent so much time on this and its getting down to crunch time for this server.
Thanks

No,as long as the jumper ID's are set up correctly,you can have it in any order you want.
On hot swap backplanes,moving drives out of their original order will cause issues in that the ID's are assigned according to slot number.
The SCSI card auto terminates, so as long as the SCSI devices are between the termination and not outside of it ,you should be fine.

Storage
Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

if you swap the first adn last drive adn try again and the siiue follows the drive then its the drive, if it stays with the slot then it is the backplane.
if issue with the drive try connecting it to a standard scsi adapter and run a verify on the drive.
this is all provided this is a new array you are creating, not an existing array with data already on the disk.
