Hmm, didn't try that.  I did do a "blockdev --rereadpt /dev/XXX", which purports to do the same thing, but that didn't work either.
 Even though I had disabled the VG, something was still looking at it.

If I remember right (it's been a while), if your SCSI/HBA module (e.g.
qlaXXXX) isn't in use for any other devices rmmod then modprobe-ing it
will cause a re-read of the partition tables.

If you have multiple LUNs mounted via the same device I think there
are scripts you can use to re-probe available devices and their
partition tables.

Will.
