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 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 subcompo‐
nent 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 compo‐
nents containing soft partitions to be deleted.
hot_spare_pool ... Specifies the name(s) of the hot spare pools to
be deleted. Names for hot spare pools can be
any legal file name that is composed of
alphanumeric characters, a dash ("-"), an
underscore ("_"), or a period ("."). Names must
begin with a letter. The words "all" and "none"
are reserved and cannot be used.
