How to unregister Resource Group LDom without Stop it.

Question

Hello,I created a Resource Group and Resource Ldom in test ( SUN Cluster 4.2). Now I would like to remove these Resource Group and Resource LDom without stop the LDom itself.
If i'm following the Oracle DOC, the LDom become in inactive state.
clrs disable LDM-sovxxxxx
clrs delete LDM-sovxxxxx
root@ddom14:/etc/cluster/ccr/global# ldm ls

Is there any way to do that.....
Than's for your help

Hi Willy,
when the LDom is configured in a SUNW.ldom resource then it is in the control from the rgm (resource group manager) of Solaris Cluster software.
And yes, if you disable the SUNW.ldom or delete it with ‘delete -F’ then the LDom goes down which is expected behavior.
I don’t know what you like to reach, but maybe ‘quiesce’ or ‘suspend’ the resource group could help?
quiesce:
This command stops a resource group from continuously switching from one node or zone to another node or zone if a START or STOP method fails.
Use the -k option to kill methods that are running on behalf of resources in the affected resource groups. If you do not specify the -k option, methods are allowed to continue running until they exit or exceed their configured timeout.
suspend:
To prevent the resource group from coming online automatically, use the suspend subcommand to suspend the automatic recovery actions of the resource group. To resume automatic recovery actions, use the resume subcommand.
More details in the man page of clrg.
