/sbin/lvm.static in rhel4.0 systems

RHEL 4.0 has lvm2. There is an executable file /sbin/lvm.static, and this is to explain what it does.

     o The full set of LVM2 commands is now installed in /usr/sbin/. In boot
       environments where /usr/ is not available, it is necessary to prefix
       each command with /sbin/lvm.static (/sbin/lvm.static vgchange -ay, for 
       example).

       In environments where /usr/ is available, it is no longer necessary to
       prefix each command with lvm (/usr/sbin/lvm vgchange -ay becomes
       /usr/sbin/vgchange -ay, for example).

     o The new LVM2 commands (such as /usr/sbin/vgchange -ay and 
       /sbin/lvm.static vgchange -ay) detect if you are running a 2.4 kernel,
       and transparently invoke the old LVM1 commands if appropriate. The
       LVM1 commands have been renamed to end with ".lvm1" (for example, 
       /sbin/vgchange.lvm1 -ay).
