+# vdev_id: udev helper to generate user-friendly names for JBOD disks
+#
+# This script parses the file /etc/zfs/vdev_id.conf to map a
+# physical path in a storage topology to a channel name. The
+# channel name is combined with a disk enclosure slot number to
+# create an alias that reflects the physical location of the drive.
+# This is particularly helpful when it comes to tasks like replacing
+# failed drives. Slot numbers may also be re-mapped in case the
+# default numbering is unsatisfactory. The drive aliases will be
+# created as symbolic links in /dev/disk/by-vdev.
+#
+# The only currently supported topologies are sas_direct and
+# sas_switch. A multipath mode is supported in which dm-mpath
+# devices are handled by examining the first-listed running
+# component disk. In multipath mode the configuration file
+# should contain a channel definition with the same name for
+# each path to a given enclosure.

+.SH NAME
+vdev_id.conf \- Configuration file for vdev_id
+.SH DESCRIPTION
+.I vdev_id.conf
+is the configuration file for
+.BR vdev_id (8).
+It controls the default behavior of
+.BR vdev_id (8)
+while it is mapping a disk device name to an alias.
+.PP
+The
+.I vdev_id.conf
+file uses a simple format consisting of a keyword followed by one or
+more values on a single line. Any line not beginning with a recognized
+keyword is ignored. Comments may optionally begin with a hash
+character.
+
+The following keywords and values are used.
+.TP
+\fIchannel\fR [pci_slot] <port> <name>
+Maps a physical path to a channel name (typically representing a single
+disk enclosure).
+
+\fIpci_slot\fR - specifies the PCI SLOT of the HBA
+hosting the disk enclosure being mapped, as found in the output of
+.BR lspci (8).
+This argument is not used in sas_switch mode.
+
+\fIport\fR - specifies the numeric identifier of the HBA or SAS switch port
+connected to the disk enclosure being mapped.
+
+\fIname\fR - specifies the name of the channel.
+
+.TP
+\fIslot\fR <old> <new>
+Maps a disk slot number as reported by the operating system
+to an alternative slot number.
+.TP
+\fImultipath\fR <yes|no>
+Specifies whether
+.BR vdev_id (8)
+will handle only dm-multipath devices. If set to "yes" then
+.BR vdev_id (8)
+will examine the first running component disk of a dm-multipath
+device as listed by the
+.BR multipath (8)
+command to determine the physical path.
+.TP
+\fItopology\fR <sas_direct|sas_switch>
+Identifies a physical topology that governs how physical paths are
+mapped to channels.
+
+\fIsas_direct\fR - in this mode a channel is uniquely identified by
+a PCI slot and a HBA port number
+
+\fIsas_switch\fR - in this mode a channel is uniquely identified by
+a SAS switch port number
+
+.TP
+\fIphys_per_port\fR <num>
+Specifies the number of PHY devices are associated with a SAS HBA port or SAS
+switch port.
+.BR vdev_id (8)
+internally uses this value to determine which HBA or switch port a
+device is connected to. The default is 4.
+.SH EXAMPLES
+A non-multipath configuration with direct-attached SAS enclosures and an
+arbitrary slot re-mapping.

+.SH DESCRIPTION
+The \fBvdev_id\fR command is a udev helper which parses the file
+.BR /etc/zfs/vdev_id.conf (5)
+to map a physical path in a storage topology to a channel name. The
+channel name is combined with a disk enclosure slot number to create an
+alias that reflects the physical location of the drive. This is
+particularly helpful when it comes to tasks like replacing failed
+drives. Slot numbers may also be re-mapped in case the default
+numbering is unsatisfactory. The drive aliases will be created as
+symbolic links in /dev/disk/by-vdev.
+
+The only currently supported topologies are sas_direct and
+sas_switch. A multipath mode is supported in which dm-mpath
+devices are handled by examining the first-listed running
+component disk as reported by the
+.BR multipath (8)
+command. In multipath mode the configuration file should contain a
+channel definition with the same name for each path to a given
+enclosure.
+
+.SH OPTIONS
+.TP
+\fB\-c\fR <config_file>
+Specifies the path to an alternate configuration file. The default is
+/etc/zfs/vdev_id.conf.
+.TP
+\fB\-d\fR <device>
+This is the only mandatory argument. Specifies the name of a device
+in /dev, i.e. "sda".
+.TP
+\fB\-g\fR <sas_direct|sas_switch>
+Identifies a physical topology that governs how physical paths are
+mapped to channels.
+
+\fIsas_direct\fR - in this mode a channel is uniquely identified by
+a PCI slot and a HBA port number
+
+\fIsas_switch\fR - in this mode a channel is uniquely identified by
+a SAS switch port number
+.TP
+\fB\-m\fR
+Specifies that
+.BR vdev_id (8)
+will handle only dm-multipath devices. If set to "yes" then
+.BR vdev_id (8)
+will examine the first running component disk of a dm-multipath
+device as listed by the
+.BR multipath (8)
+command to determine the physical path.
+.TP
+\fB\-p\fR <phys_per_port>
+Specifies the number of PHY devices associated with a SAS HBA port or SAS
+switch port.
+.BR vdev_id (8)
+internally uses this value to determine which HBA or switch port a
+device is connected to. The default is 4.
+.TP
+\fB\-h\fR
+Print a usage summary.
