Hardware RAID card, array migrated, refresh /dev/sdc to show new size

Hi everyone

Should be a quick one to answer...
I've just migrated an array on my hardware RAID card (3Ware 9690SA-8i) from RAID 1 to RAID 0 to try some basic benchmarking.

However when I run fdisk -l the device I migrated /dev/sdc is still showing the old capacity of when it was a RAID 1. With RAID 0 it should have double the capacity.

Is there any sort of refresh I need to do under CentOS to tell the system that /dev/sdc has changed?

All the other drives and partitions in the system and on the RAID card are the same.
There's no data/partitions on the device in question /dev/sdc

Any ideas?

Cheers, B

Sorted...

Code:

hdparm -z /dev/sdc

Did the trick ;)
