OS does not see resized NetAPP Lun

All, I have resized a NetApp FC lun from 20g to 30g, however my Oracle Enterprise Linux 5 (IBM x3850s with Qlogic HBAs), doesn't see the lun change. When I type "multipath", it still reports the lun as 20g, however the QLogic scli utility does see the resized lun as 30g. As such, I'm at a loss. How do I get the Linux box to see the resized LUN without rebooting or something drastic like that? The lun forms an ASM diskgroup that is low on space and I want to increase that diskgroup size by 10g.

Thanks for any and all help.
