Hi

Have you tried

ldm stop -f dev01-lgdm06

that should force the domain to stop.

Failing that do

ldm set-var auto-boot\?=false dev01-lgdm06

ldm add-config

(just to make sure you have kept settings)

powercycle the box

on rebooting the control domain dev01-lgdm06 ifstarted will be at the

ok prompt and so a normal ldm stop will stop it.

Hi

Do a ldm set-vcpu primary

ldm set-vmem primary

reboot

this will put all resources in domain primary

do a package remove of the SUNWldm package ( and

SUNWldmp2v )

and reboot again

All domain information will have gone

Personally i'd reset back to factory defaults IIRC:

stop and unbind each ldom

# ldm set-config factory-default

and reboot

or from ALOM:

sc> bootmode config="factory-default"

sc> powercycle -y

Here's a script.....

#!/usr/bin/sh

# Disable Logical Domains and restore machine to

factory default

# configuration.

#

LDMCMD=/opt/SUNWldm/bin/ldm

PLATFORM=`/usr/bin/uname -i | /usr/bin/awk -

F, '{print $2}'`

if [ "${PLATFORM}" = "Sun-Fire-T200" ]

then

NICDRIVER=e1000g

elif [ "${PLATFORM}" = "T5140" ]then

NICDRIVER=nxge

elif [ "${PLATFORM}" = "SPARC-Enterprise-T5220" ]

then

NICDRIVER=e1000g

elif [ "${PLATFORM}" = "Sun-Blade-T6320" ]

then

NICDRIVER=e1000g

elif [ "${PLATFORM}" = "T5240" ]

then

NICDRIVER=nxge

else

echo "Error"

echo "Error"

echo "Error"

echo " "

echo "Please add the platform $PLATFORM and NIC

echo "add $PLATFORM"

To wipe LDOMs froma amachine and install a fresh

OS...

You can set up all that is neccessary from the

service processor, run the

following commands...

(using the ILOM CLI)

stop /SYS

set /HOST/bootmode config='factory-default'

start /SYS

(or Using ALOM CLI)

poweroff -y -f

bootmode config="factory-default"

poweron

This forces the system to reboot as a whole

machine single domain on the next

reboot (the setting is only active for a few

minutes, so reboot soon after

setting this)

Then a conventional re-install can be done... by

DVD or network.

You can further streamline this by adding

script="boot net - install"

on the end of the 'set' or 'bootmode' command

lines, this will force a network

install on reboot presuming you have a jumpstart

environment setup.

Peter,

Is there a way to do this w/out having to do a OS

reinstall? It has been

a while since I have worked with this software buthoping an option

would be to do the ILOM step you give below in

conjunction with removal

of LDOM packages to get back to "whole" system.

Thoughts?

Yes - you do not need to do an OS install, just

that the original poster

wanted to do this.

Sure, just do the config=factory-default option,

Reboot and then at the OS do the following

procedures...

ldm list

ldm destroy

ldm list-spconfig

ldm rm-spconfig

svcadm disable vntsd

svcadm disable ldmd

pkgrm

Remember to destroy any disk images you may have

set up for your guests...

eg.

zpool list

zpool destroy

If you associated any vsw devices with your

network ports in the primary

domain rememeber to rename the default network

device..

mv /etc/hostname.vxw /etc/hostname.

I think thats about it...
