 NAME
      pvck - check or repair a physical volume in LVM volume group

 SYNOPSIS
      /usr/sbin/pvck -y pv_path

      /usr/sbin/pvck -n pv_path

 DESCRIPTION
      Note: Currently pvck is only capable of detecting bad checksums caused
      by a forward system migration after a backward system migration. It
      should not be used in other situations.

      The pvck command examines and repairs LVM data structures on a raw
      disk (pv_path) in a volume group.

    Options and Arguments
      pvck recognizes the following options and arguments.

	   -y		  Repair problems found.

	   -n		  Report, but do not repair problems.

	   pv_path	  The raw device path name of a physical volume.

 RETURN VALUE
      pvck returns the following values

	   0	Either no problems were found or all problems were
		corrected.

	   1	Unable to repair.

 EXAMPLES
      Examine LVM checksums on /dev/rdsk/c0t6d0 without modifying anything:

	   pvck -n /dev/rdsk/c0t6d0

      Repair LVM checksums on /dev/rdsk/c0t6d0 if necessary:

	   pvck -y /dev/rdsk/c0t6d0

 WARNINGS
      pvck should only be run on a device whose volume group has not been
      activated.

      It is designed to repair the root device or devices while the system
      is booted in maintenance mode ("hpux -lm", see hpux(1M)).
