Is quite easy. But before undoing anything. You need to compare metadevices to filesystem.

If your metadevices are concatted or striped across more than 1 disk, that filesystem cannot undo, if you undo you will lose data. To fix this I guess you have to backup the data to tape or create a new non-sds single disk slice filesystem large enough to hold that data, it can be time consuming depending on the size of your data.

But if once you established 1 metadevice --> 1 disk slice then next thing is to rewrite your vfstab file to mount block devices change the /dev/md/dsk to /dev/dsk, it helps if you had the original before the OS was under SDS otherwise you have to write it yourself.

Lastly you need to edit out or delete the following in /etc/system.

* Begin MDD root info (do not edit)
forceload: misc/md_trans
forceload: misc/md_raid
forceload: misc/md_hotspares
forceload: misc/md_sp
forceload: misc/md_stripe
forceload: misc/md_mirror
forceload: drv/pcisch
forceload: drv/qlc
forceload: drv/fp
forceload: drv/ssd
rootdev:/pseudo/md@0:0,0,blk
* End MDD root info (do not edit)

If you fail to do this and reboot the system, the system may start to go into a looping panic.

Once you are sure re-configured everything properly do the reboot. BUT DO NOT DO METACLEAR on any metadevice until you have rebooted the system at least once and the system able to come up properly.

Make sure you backup those files like I told you to. In case the whole thing screw up you can at least have a fall back.

pvremove

pvremove(1M)															      pvremove(1M)

NAME

       pvremove - remove LVM data structure from a physical volume

SYNOPSIS

DESCRIPTION

       The  command  clears  the LVM data structure on a disk, so that it is no longer an LVM physical volume.	The device may then be used by the
       file system or by other volume managers.

       The operation is denied if pv_path is assigned to a volume group.  The command only clears the LVM data structure on a  disk  if  the  disk
       does not belong to a volume group.  This avoids accidentally removing a valid physical volume under a volume group.  If the physical volume
       to be removed belongs to a volume group, use the command to first remove the volume group associated with the physical volume.

   Arguments
       recognizes the following arguments:

	      pv_path	The character (raw) device path name of a physical volume.

EXTERNAL INFLUENCES

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified or is null, it defaults to "C" (see lang(5)).

       If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).

EXAMPLES

       Remove LVM data structure on the physical volume
