Usage of "-Ay" "-cy" options in vgcreate

Question

What do the options "-Ay" "-cy" in the vgcreate command do? I checked the man page but was unable to find them.

for example:

vgcreate -Ay -cy cluster_vg /dev/vdb

From the vgcreate(8) man page:

  -c, --clustered {y|n}
          If  clustered  locking is enabled, this defaults to y indicating
          that this Volume Group is shared with other nodes in  the  clus‐
          ter.

          If  the  new Volume Group contains only local disks that are not
          visible on the other nodes, you must specify --clustered n.   If
          the  cluster  infrastructure is unavailable on a particular node
          at a particular time, you may still be able to use  such  Volume
          Groups.

From the lvm(8) man page:

   -A, --autobackup {y|n}
          Whether or not to metadata should  be  backed  up  automatically
          after  a  change.  You are strongly advised not to disable this!
          See vgcfgbackup(8).
