/usr/sbin/metaclear component
/usr/sbin/metaclear [-s setname] [-f] metadevice... hot_spare_pool...
/usr/sbin/metaclear [-s setname] -r [-f] metadevice...

/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 com‐
ponent. 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 metade‐
vices 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 func‐
tion 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 compo‐
nents 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.

Example 1: Deleting Various Devices
The following example deletes a metadevice named d10.
# metaclear /dev/md/dsk/d10
The following example deletes all local metadevices and hot spare pools
on the system.
# metaclear-a
The following example deletes a mirror, d20, with an submirror in an
error state.

if those partitions are not being used by other metadevices or are not
open.
# metaclear-p c2t3d5s2
