This is (among others) useful for changing the logical volume's name

Communicates with the kernel device-mapper driver via
libdevmapper to activate (-ay) or deactivate (-an) the
logical volumes.
.IP
If clustered locking is enabled, -ae will activate exclusively
on one node and -aly will activate only on the local node.
To deactivate only on the local node use -aln.
Logical volumes with single-host snapshots are always activated
exclusively because they can only be used on one node at once.

Not used by device-mapper.
For compatability with LVM1 only. Ignored by LVM2.
.TP
.I \-\-refresh
If the logical volume is active, reload its metadata.
This is not necessary in normal operation, but may be useful
if something has gone wrong or if you're doing clustering
manually without a clustered lock manager.
.SH Examples
"lvchange -p r vg00/lvol1" changes the permission on

volume lvol1 in volume group vg00 to be read-only.
