diskowner(1M) diskowner(1M) 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. EXAMPLES
Display the owner of a disk path: Display the owner of a logical volume in compact output: Display all the owners of a disk path: Display all the owners of a logical volume in compact output: SEE ALSO
