metaclear – delete active metadevices and hot spare pools
/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
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. 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.
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 in the form hspnnn, where nnn is a number in the range 000-999.
