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  admin-
		     istrative	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. 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.

EXAMPLES
       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, mymirror, with a submirror in an error state.

	 # metaclear -f mymirror

       The following example deletes a hot spare pool, hsp001.

	 # metaclear hsp001

       The following example deletes a soft partition, d23.

	 # metaclear d23

       The following example purges all soft partitions on the slice c2t3d5s2 if those partitions are not being used by other metadevices  or  are
       not open.

	 # metaclear -p c2t3d5s2

       The following example purges soft partitions from a metadevice.

	 # metaclear -p d2
	 d3: Soft Partition is cleared
	 d4: Soft Partition is cleared
	 d5: Soft Partition is cleared

EXIT STATUS
       The following exit values are returned:

       0     Successful completion.

       >0    An error occurred.
