Make sure you have a current backup of all data and that you have root privilege.
Make sure 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 gone 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 instructions. For more information, see the online help.
Use the following format of the metaclear command to delete the volume:
See the following example and the metaclear(1M) man page for more information.
# umount d8 # metaclear d8 d8: Concat/Stripe is cleared (Edit the /etc/vfstab file)
This example illustrated clearing the concatenation d8 that also contains a mounted file system. The file system must be unmounted before the volume can be cleared. The system displays a confirmation message that the concatenation is cleared. If there is an entry in the /etc/vfstab file 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.
