diskowner(1M) diskowner(1M)

NAME

diskowner - retrieve the owner of a storage device

SYNOPSIS

/usr/sbin/diskowner

[-A][-F] path

DESCRIPTION

The

diskowner 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 com-

mand will print out the owner of the path, or

none 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

diskowner 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.

-A List all the owners of the speciﬁed path, seperated by commas (

,).

-F Produce a compact output that is easily parsed by other scripts and programs. When used

with -A option, displays all the owners seperated by dots (.). This format is described in the

Compact Listing section below.

Output from diskowner

diskowner displays the following possible output:

owner The owner of the given path. owner can be one of the following:

none The path is not owned by any known subsystem.

lvm The path is part of an LVM volume group.

vxvm The path is part of a VxVM volume group.

vxfs The path has a VxFS ﬁlesystem on it.

hfs The path has a HFS ﬁlesystem on it.

swap The path is being used as a swap device.

dump The path is being used as a dump device.

asm The path is part of an Oracle database.

partition The path has EFI partitions on it.

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

Compact Listing

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

key1

=value1:key2=value2

and so forth.

The

-F option, when used with the -A option, produces this output format:

key1

=value1:key2=value21.value22.value23.....value2n

and so forth.

The current

diskowner command prints out the keys and values listed below. In the future, new keys

and/or values may be added to the output.

path=path :owner=owner

path=path:owner=owner1.owner2.owner3.....ownern

path=path :error=message

where

path is the pathname passed as argument
