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 admin- istrative 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. 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.
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
