Short version of the question:
How to remove LSM rootdg?
Long version of the question:
The Logical Storage Manager Support Operations, voldiskadm,
tells me:
----------------------------------------------------------------
List disk information
Menu: LogicalStorageManager/Disk/ListDisk
Use this menu operation to display a list of disks. You can
also choose to list detailed information about the disk at
a specific disk device name.
Enter disk device or "all"
[<disk/partition name>,all,q,?] (default: all)
DEVICE DISK GROUP STATUS
rz4 rz4 rootdg online
Device to list in detail
[<disk/partition name>,none,q,?] (default: none)
----------------------------------------------------------------
so, I foolishly try to remove a disk from rootdg, but since it
is the last one, it says no way, but politely tells me to
"Disable access to (deport) a disk group".
----------------------------------------------------------------
Remove a disk
Menu: LogicalStorageManager/Disk/RemoveDisk
Use this operation to remove a disk from a disk group. This
operation takes, as input, a disk name. This is the same name
that you gave to the disk when you added the disk to the disk
group.
Enter disk name [<disk>,list,q,?] list
Disk group: rootdg
DM NAME DEVICE TYPE PRIVLEN PUBLEN PUBPATH
dm rz4 rz4 sliced 512 8387787 /dev/rrz4h
Enter disk name [<disk>,list,q,?] rz4
Disk rz4 cannot be removed from disk group rootdg because
it is the last disk in the disk group. You may want to remove
the disk group instead. To remove the disk group, quit from this
operation and select "Disable access to (deport) a disk group"
from the main disk operations menu.
Remove a different disk? [y,n,q,?] (default: n)
-------------------------------------------------------------------
fine, back to the menu, hmmmm, no "Disable access to (deport) a disk group"
maybe they mean
9 Remove access to (deport) a disk group

try number 9, this looks promising....
------------------------------------------------------------------
Remove access to (deport) a disk group
Menu: LogicalStorageManager/Disk/DeportDiskGroup
Use this menu operation to remove access to a disk group that
is currently enabled (imported) by this system. Deport a disk
group if you intend to move the disks in a disk group to another
system. Also, deport a disk group if you want to use all of the
disks remaining in a disk group for some new purpose.
You will be prompted for the name of a disk group. You will
also be asked if the disks should be disabled (offlined). For
removable disk devices on some systems, it is important to
disable all access to the disk before removing the disk.
Enter name of disk group [<group>,list,q,?] (default: list)
GROUP DISK/VOLUME DEVICE/STATE LENGTH
Enter name of disk group [<group>,list,q,?] (default: list)
---------------------------------------------------------------------
hey, where did the rootdg go? It was here a minute ago?
I'll try it anyway....fools rush in...
---------------------------------------------------------------------
Enter name of disk group [<group>,list,q,?] (default: list) rootdg
The rootdg disk group cannot be removed.
Select a different disk group? [y,n,q,?] (default: n)
--------------------------------------------------------------------
"rootdg disk group cannot be removed", zippidy-do-dah, zippidy-ay,
my oh, my, what a wonderful day.
