Make sure you have met the prerequisites ("Prerequisites for Removing DiskSuite Objects") and have read the preliminary information ("Preliminary Information for Removing RAID5 Metadevices").
Make sure you have a current backup of the metadevice.
Stop access to the RAID5 metadevice.
For example, a file system should be unmounted. For a non-UFS application, such as a database, perform the steps necessary to stop the application's use of the metadevice.
Double-click the RAID5 object to be deleted in the Objects list.
The RAID5 object appears on the canvas.
Display the RAID5 object's pop-up menu and select Delete.
Click Really Delete on the dialog box that is displayed.
[Optional] If there is an entry in the /etc/vfstab file for this metadevice, delete that entry.
You do not want to confuse the system by asking it to mount a file system on a non-existent device.
To verify that the object was deleted, display the Configuration Log.
Hot spare pools assigned to the metadevice are not deleted.
