I am having trouble understanding the difference between a passthrough device and a named device and when you would use one or the other to access equipment.

metaclear
metaclear(1M) System Administration Commands metaclear(1M)NAME
metaclear - delete active metadevices and hot spare pools
SYNOPSIS
/usr/sbin/metaclear -h
/usr/sbin/metaclear [-s setname] -a [-f]
/usr/sbin/metaclear component
/usr/sbin/metaclear [-s setname] [-f] metadevice... hot_spare_pool...
/usr/sbin/metaclear [-s setname] -r [-f] metadevice... hot_spare_pool...
/usr/sbin/metaclear [-s setname] -p component
/usr/sbin/metaclear [-s setname] -p metadevice
DESCRIPTION
The metaclear command deletes the specified metadevice or hot_spare_pool., or purges all soft partitions from the designated component.
Once a metadevice or hot spare pool is deleted, it must be re-created using metainit before it can be used again.
Any metadevice currently in use (open) cannot be deleted.
OPTIONS
Root privileges are required for all of the following options except -h.
-a Deletes all metadevices and configured hot spare pools in the set named by -s, or the local set by default.
-f Deletes (forcibly) a metadevice that contains a subcomponent in an error state.
-h Displays usage message.
-p Deletes (purges) all soft partitions from the specified metadevice or component.
-r Recursively deletes specified metadevices and hot spare pools, but does not delete metadevices on which others
depend.
-s setname Specifies the name of the diskset on which metaclear will work. Using the -s option causes the command to perform
its administrative function within the specified diskset. Without this option, the command performs its function on
local metadevices and/or hot spare pools.
OPERANDS
metadevice ... Specifies the name(s) of the metadevice(s) to be deleted.
component Specifies the c*d*t*s* name(s) of the components containing soft partitions to be deleted.
hot_spare_pool ... Specifies the name(s) of the hot spare pools to be deleted in the form hspnnn, where nnn is a number in the range
000-999.

# metaclear -a
The following example deletes a mirror, d20, with an submirror in an error state.

not open.
# metaclear -p c2t3d5s2
The following example purges soft partitions from a metadevice.
