WARNINGS
If the Mass Storage Subsystem multipath solution is enabled, the
pvchange command options that are
link specific may not stop I/Os or switch links, as they did in earlier releases. This means that
pvchange -a n, pvchange -s, and
pvchange -S may not stop all I/Os on a given path. The
scsimgr command should be used to disable the links.
When the proactive polling is enabled, LVM will not be testing alternate links unless legacy mode is in
operation, even if legacy paths are being used.
