[linux-lvm] Detecting device growth (SAN environment)

Hello all, I have a SAN environment that is working fine but I seem to
be unable to see new space added to the LUNs via the SAN console. I have
googled a LOT and even came across this old thread on this list from
over a year ago:
https://www.redhat.com/archives/linux-lvm/2005-January/msg00080.html
My main problem seems to be that I can not find a way to get the OS to
see the new size of the LUN, even after rescanning the SCSI bus, running
fdisk, doing pvscan, etc. I even tried the suggested blockdev --rereadpt
/dev/sdx command but I got a BLKRRPART: Device or resource busy, even
tho there is nothing on the device.
Does anyone have any clues on how to get Linux (2.6 kernel, SuSE Linux
Enterprise Server) to notice that an underlying scsi LUN has changed in
size?
Thanks in advance,
Chris
