Removing LDOMs & Virtual Services

When a guest is no longer needed, you should remove it cleanly: shut down, detach virtual devices, delete the domain and clean up backend storage. This avoids orphaned configs and wasted space.

High-level removal steps

Order of operations

Stop and unbind domain.
Remove vdisks and vnets from domain.
Remove backend vdsdev from service domain.
Delete domain.
Destroy ZFS volumes if no longer needed.

Commands and example

1. Stop and unbind a guest domain

Before removal, halt and unbind the domain.

terminal — ldom cleanup

ldoms-lab

[root@primary ~]# ldm stop ldg1
[root@primary ~]# ldm unbind ldg1

2. Remove vdisks and vnets

Detach front-end devices from guest.

terminal — ldom cleanup

ldoms-lab

[root@primary ~]# ldm list -l ldg1 | egrep 'VDISK|VNET'
 
# Example:
[root@primary ~]# ldm remove-vdisk dvd0 ldg1
[root@primary ~]# ldm remove-vdisk vdisk0 ldg1
[root@primary ~]# ldm remove-vnet vnet0 ldg1

3. Delete the guest domain

Once devices removed, delete the domain definition.

terminal — ldom cleanup

ldoms-lab

[root@primary ~]# ldm remove-domain ldg1

4. Remove backend vdsdev and ZFS volumes

Clean up backend resources on service domain.

terminal — ldom cleanup

ldoms-lab

# Remove backend device from vds
[root@primary ~]# ldm remove-vdsdev ldg1-root@primary-vds0
 
# Destroy ZFS volume
[root@primary ~]# zfs destroy rpool/ldoms/ldg1-root

Be careful before deleting

Take backups or snapshots if there is any chance of reuse.
Double-check domain name; do not remove the wrong guest.
Verify no other domains use the same backend ZFS volume.
