-.Sh NAME
-.Nm geom_fox
-.Nd "GEOM based basic disk multipathing"
-.Sh SYNOPSIS
-To compile this driver into the kernel,
-place the following line in your
-kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "options GEOM_FOX"
-.Ed
-.Pp
-Alternatively, to load the driver as a
-module at boot time, place the following line in
-.Xr loader.conf 5 :
-.Bd -literal -offset indent
-geom_fox_load="YES"
-.Ed
-.Sh DESCRIPTION
-.Bf -symbolic
-This driver is obsolete.
-Users are advised to use
-.Xr gmultipath 8
-instead.
-This driver will be removed in
-.Fx 12 .
-.Ef
-.Pp
-The intent of the
-.Nm
-framework is to provide basic multipathing support to access direct
-access devices.
-Basic in the above sentence should be read as:
-.Nm
-only provides path failover functionality, not load balancing over
-the available paths etc.
-Using suitable hardware like SCSI or FibreChannel disks it is
-possible to have multiple (typically 2) host bus adapters access
-the same physical disk drive.
-.Pp
-Without a multipathing driver the
-.Fx
-kernel would probe the disks multiple times, resulting in the creation of
-multiple
-.Pa /dev
-entries for the same underlying physical device.
-A unique label written in the GEOM label area allows
-.Nm
-to detect multiple paths.
-Using this information it creates a unique
-.Pa da#.fox
-device.
-.Pp
-The
-.Nm
-device is subsequently used by the
-.Fx
-kernel to access the disks.
-Multiple physical access paths ensure that even in case of a path failure the
-.Fx
-kernel can continue to access the data.
-.Pp
-The
-.Nm
-driver will disallow write operations to the underlying devices once the
-fox device has been opened for writing.
-.Sh EXAMPLES
-.Bl -bullet -compact
-.It
-.Nm
-needs a label on the disk as follows in order to work properly:
-.Bd -literal
-"0123456789abcdef0123456789abcdef"
-"GEOM::FOX <--unique--id-->"
-.Ed
-.Pp
-For the unique ID 16 bytes are available.
-The
-.Dq Li GEOM::FOX
-is the magic to mark a
-.Nm
-device.
-.Pp
-The actual labelling is accomplished by
-.Bd -literal
-echo "GEOM::FOX someid" | dd of=/dev/da2 conv=sync
-.Ed
-.Pp
-For FibreChannel devices it is suggested to use the Node World Wide
-Name (Node WWN) as this is guaranteed by the FibreChannel standard to
-be worldwide unique.
-The use of the Port WWN not recommended as each port of a given
-device has a different WWN, thereby confusing things.
-.Pp
-The Node WWN can be obtained from a verbose boot as in for example
-.Bd -literal
-isp1: Target 1 (Loop 0x1) Port ID 0xe8 (role Target) Arrived
- Port WWN 0x21000004cfc8aca2
- Node WWN 0x20000004cfc8aca2
-.Ed
-.Pp
-This Node WWN would then be used like so:
-.Bd -literal
-echo "GEOM::FOX 20000004cfc8aca2" | dd of=/dev/da2 conv=sync
-.Ed
-.Pp
-For non-FibreChannel devices you could for example use the serial
-number of the device.
-Regardless of what you use, make sure the label is unique.
-.Pp
-Once the labelling has been performed and assuming the
-.Nm
-module is loaded the kernel will inform you that it has found a new
-.Nm
-device with a message similar to
-.Bd -literal
-Creating new fox (da2)
-fox da2.fox lock 0xfffffc0000fdba20
-.Ed
-.Pp
-.It
-To check which physical devices match a given
-.Nm
-device:
-.Bd -literal -offset indent
-# geom fox list
-Geom name: da2.fox
-Providers:
-1. Name: da2.fox
- Mediasize: 73407865344 (68G)
- Sectorsize: 512
- Mode: r0w0e0
-Consumers:
-1. Name: da2
- Mediasize: 73407865856 (68G)
- Sectorsize: 512
- Mode: r0w0e0
-2. Name: da6
- Mediasize: 73407865856 (68G)
- Sectorsize: 512
- Mode: r0w0e0
-.Ed
-.Pp
-.It
-To check the status of the
-.Nm
-components:
-.Bd -literal
-# geom fox status
- Name Status Components
-da2.fox N/A da2
- da6
-.Ed
-.El
-.Sh SEE ALSO
-.Xr GEOM 4 ,
-.Xr geom 8 ,

-The
-.Nm
-driver was written by
-.An Poul-Henning Kamp Aq Mt phk@FreeBSD.org .
-This manual page was written by
-.An Wilko Bulte Aq Mt wilko@FreeBSD.org .
-.Sh CAVEATS
-The
-.Nm
-driver depends on the underlying hardware drivers to do the right thing in case
-of a path failure.
-If for example a hardware driver continues to retry forever,
-.Nm
-is not able to re-initiate the I/O to an alternative physical path.
-.Pp
-You have to be very sure to provide a unique label for each of the
-.Nm
-devices.
-Safety belts are not provided.
-For FibreChannel devices it is suggested to use the Port WWN of the device.
-The World Wide Name is guaranteed to be worldwide unique per the
-FibreChannel standard.
-.Sh BUGS
-The
-.Nm
-framework has only seen light testing.
-There definitely might be dragons here.
-.Pp
-The name
-.Nm
-is completely obscure.
-Just remember that any sly fox has multiple exits from its hole.
-.Pp
-The examples provided are too FibreChannel-centric.
