Really old post guys sorry.
I finaly have time to do this but I noticed when i mount sdc1 it is exactly the same as sdd1:

Code:
 
RCWLO-ODS10g:/NEWSAN/backup # df -k /NEWSAN
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sdc1            1373587836 683999232 689588604  50% /NEWSAN
RCWLO-ODS10g:/NEWSAN/backup # df -k /SAN
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sdd1            1373587836 683999232 689588604  50% /SAN
RCWLO-ODS10g:/NEWSAN/backup #

Does this mean sdc1 is the mirror of sdd1?

Code:
 
RCWLO-ODS10g:/NEWSAN/backup # fdisk -l

Any assistance would be appreciated.

Thanks

Have you managed to ask the service technicians what the capacity of the disk was and where it came from? That would help a LOT. Right now all we're doing is guessing.

It may be a mirror. Do you have a /dev/md0, md1, etc? That's a software RAID device that combines multiple disks into one device. Try 'cat /proc/mdstat'

Yes it's 1 TB.
We just rebooted the server and fdisk -l still doesn't show any new disk. Its the same as before.

Maybe there's something wrong with how it's connected to the server? Not too sure.

If there is, Linux couldn't tell you. How's it supposed to tell you what's wrong with a disk it can't see? Someone needs to do some basic hardware troubleshooting on this system. We don't even know if the BIOS sees this drive. We don't even know what the drive is except it's "terabyte".

All sorted out.
The Tech didn't have it set up properly. Big surprise. He said 'Hold on a sec... ok try it now' and fdisk -l showed the new disk.

I created the partition, mounted it and got all my Oracle data moved over.

Thanks for all who helped me with this.
