Multipath device manageability improvements
Update udev helper scripts to deal with device-mapper devices created by multipathd. These enhancements are targeted at a particular storage network topology under evaluation at LLNL consisting of two SAS switches providing redundant connectivity between multiple server nodes and disk enclosures. The key to making these systems manageable is to create shortnames for each disk that conveys its physical location in a drawer. In a direct-attached topology we infer a disk's enclosure from the PCI bus number and HBA port number in the by-path name provided by udev. In a switched topology, however, multiple drawers are accessed via a single HBA port. We therefore resort to assigning drawer identifiers based on which switch port a drive's enclosure is connected to. This information is available from sysfs. Add options to zpool_layout to generate an /etc/zfs/zdev.conf using symbolic links in /dev/disk/by-id of the form <label>-<UUID>-switch-port:<X>-slot:<Y>. <label> is a string that depends on the subsystem that created the link and defaults to "dm-uuid-mpath" (this prefix is used by multipathd). <UUID> is a unique identifier for the disk typically obtained from the scsi_id program, and <X> and <Y> denote the switch port and disk slot numbers, respectively. Add a callout script sas_switch_id for use by multipathd to help create symlinks of the form described above. Update zpool_id and the udev zpool rules file to handle both multipath devices and conventional drives.

# means to infer the physical topology. For a single-level network

# (i.e. no switch cascading) we can assign alphabetic channel labels
|

# based on the switch port number that the drawer is connected to.

# If support for more complex topologies is needed this script will

# need to be customized or replaced.

# In SAS-Switch mode (enabled with "-g switch" ) we require that

# udev has been configured to create per-disk symbolic links in

# /dev/disk/by-id of the form
|
||||
# <label>-<UUID>-switch-port:<X>-slot:<Y>. <label> is a string that
|

# depends on the subsystem that created the link and defaults to
