How to Remove a RAID-0 Volume
Make sure that you have a current backup of all data and that you have root privilege.
Make sure that you no longer need the volume.
If you delete a stripe or concatenation and reuse the slices that were part of the deleted volume, all data on the volume is deleted from the system.
Unmount the file system, if needed.
# umount /filesystem
To remove a volume, use one of the following methods:
From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node. Choose Edit⇒Delete, then follow the onscreen instructions. For more information, see the online help.
Use the following format of the metaclear command to delete the volume:
metaclear volume-name
See the following example and the metaclear ( 1M ) man page for more information.
Example 9.8. Removing a Concatenation
#umount d8#metaclear d8d8: Concat/Stripe is cleared (Edit the /etc/vfstab file)
This example illustrates removing the concatenation, d8,
that also contains a mounted file system. The file system must be unmounted
before the volume can be removed. The system displays a confirmation message
that the concatenation is removed. If an entry in the /etc/vfstab file
exists for this volume, delete that entry. You do not want to confuse the
system by asking it to mount a file system on a nonexistent volume.
