NAME

       diskowner - retrieve the owner of a storage device

SYNOPSIS

       path

DESCRIPTION

       The  command  is  used to retrieve the subsystem, if any, which is using the specified path.  The command is intended to help prevent users
       from overwriting storage that is already in use.  The command will print out the owner of the path, or if no owner was  found.	A  storage
       device  is  considered owned by a subsystem if it has been formatted by that subsystem.	For example, if a disk contains a VxFS filesystem,
       but is not mounted or in use, it is still considered owned by the VxFS subsystem.

       If the path specified is invalid or inaccessible, an error message will be printed.

   Options and Arguments
       The command recognizes the following options and arguments:

       path	 The path name to the storage device.  The path may be a symbolic link, as long as it points to a storage device, such as a  file,
		 disk, or logical volume.

       List all the owners of the specified path, seperated by commas

       Produce a compact output that is easily parsed by other scripts and
		 programs.  When used with option, displays all the owners seperated by dots This format is described in the section below.

   Output from diskowner
       displays the following possible output:

       owner	 The owner of the given path.  owner can be one of the following:
		 The path is not owned by any known subsystem.
		 The path is part of an LVM volume group.
		 The path is part of a VxVM volume group.
		 The path has a VxFS filesystem on it.
		 The path has a HFS filesystem on it.
		 The path is being used as a swap device.
		 The path is being used as a dump device.
		 The path is part of an Oracle database.
		 The path has EFI partitions on it.

       message	 An error message displayed when the given path is invalid or inaccessible.

   Compact Listing
       The option generates a compact, colon delimited listing that is easy to parse.  The output format is:

       and so forth.

       The option, when used with the option, produces this output format:

       and so forth.

       The current command prints out the keys and values listed below. In the future, new keys and/or values may be added to the output.

       or
       or
       where

       path	 is the pathname passed as argument

       owner	 is the owner of the given path

       message	 is an error message when given path is invalid or inaccessible.

       n	 is number of owners of the given path

EXTERNAL INFLUENCES

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified or is null, it defaults to "C" (see lang(5)).

       If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).

RETURN VALUE

       Upon completion, returns one of the following values:
	      The path is not owned (the owner is
	      The path is already owned by a subsystem.
	      The path does not exist.
	      Invalid options or library version incompatible.
	      The path cannot be opened due to an I/O error.
	      The path cannot be opened due to insufficient permissions.
	      The path format is invalid.
