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 config-
ured 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 meta-
devices 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 per-
form its administrative function
within the specified diskset.
Without this option, the command
performs its function on local meta-
devices 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 par-
titions 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.
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, d20, with an submir-
ror in an error state.
# metaclear -f d20
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 metadev-
ice.
# metaclear -p d2
d3: Soft Partition is cleared
d4: Soft Partition is cleared
d5: Soft Partition is cleared
