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. 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 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
