hd6 is the default logical volume for the swap space in AIX systems. Perhaps you are using an AIX system, right? A "logical volume" is something similar to a disk partition in Windoze and the first swap space, which is created during installation of the machine, is per default on the volume "hd6".
Issue "lsps -a" at the command line to see all the swap spaces in your system and how much they are used at the moment.

extendfs_hfs
extendfs_hfs(1M) extendfs_hfs(1M)
NAME
extendfs_hfs: extendfs - extend HFS file system size
SYNOPSIS
size] special
DESCRIPTION
If the original HFS file system image created on special does not make use of all of the available space, the command can be used to
increase the capacity of an HFS file system by updating the file system structure to include the extra space.
The command-line parameter special specifies the character device special file of either a logical volume or a disk partition. The special
must be unmounted before the command can be run (see mount(1M)).
Options
recognizes the following options:
Specify the HFS file system type.
Query the size of
special. No file system extension will be done.
Verbose flag.
Specifies the number of
blocks to be added to the file system. If the number of blocks is not specified, the maximum possible size is used.
EXAMPLES
To increase the capacity of a file system created on a logical volume, enter:
WARNINGS
The root file system cannot be extended using the command because the root file system is always mounted, and the command only works on
unmounted file systems.
will fail if used on a file system, on a logical volume, where the logical block size of the logical volume is greater than the file sys-
tem's fragment size. The logical block size, of a logical volume changes, when additional disks with larger sector size are added.
RETURN VALUE
returns the following values:
0 No errors were detected and file system was successfully extended.
1 Command aborted.
