For anyone searching and running up on this thread.  That command did
work to disable the drive.  I'm not sure if I should have used pvchange
to disable /dev/sdk1 or not.  The problem I did run into was getting it
back.  I ran the command to enable it but it didn't work as expected.  I
had files missing.  So, I unmounted it, ran pvscan, vgscan and lvscan in
that order.  I then ran the command above again to be sure and remounted
the LV group.  It worked that time. All files were there.  So, either
one has to rescan them or I should have also ran pvchange to disable as
well.  Maybe someone else can expand on this.

While I'm at it.  Is there a way to reset the sdk part?  The old was sdd
and I was hoping when I moved the drive, it would change with it.  The
reason is, usually when I hook up my external drives, they use sdk.  I'm
sort of set up for that.  A couple other things use sdk as well.  I'm
not sure if there is a easy way to do that or not.  Wonder if it will
reset when I reboot???
