Now that the Control domain is setup, you can start creating LDOM's at will. The idea here is to create a base LDOM image that can be cloned to quickly provision new servers.

1. Create a ZFS file system to store the disk image for our LDOM

 zfs create storage/base

This will create a ZFS file system called storage/base that will be mounted at /storage/base

2. Create a ZFS disk image to hold the LDOM's data

 zfs create -V 36gb storage/base/disk0

This will create a 36Gb disk image. You can see the results in the zfs list output:

 # zfs list
 NAME                        USED  AVAIL  REFER  MOUNTPOINT
 storage                    37.1G   630G  36.5K  /storage
 storage/base               37.1G   630G  34.9K  /storage/base
 storage/base/disk0         37.1G   667G  26.6K  -
 .....

3. Create the new LDOM

 ldm add-domain base

4. Assign virtual CPU's to the new LDOM

 ldm add-vcpu 8 base

5. Assign memory to the new LDOM

 ldm add-memory 2G base

6. Create a virtual disk device and assign it to the new LDOM

 ldm add-vdsdev /dev/zvol/dsk/storage/base/disk0 base-vol1@primary-vds0
 ldm add-vdisk vdisk1 base-vol1@primary-vds0 base

This creates a virtual disk device called base-vol1@primary-vds0 that is then assigned to the LDOM base. ldm list-services should now look like this:

 VCC
    NAME             LDOM             PORT-RANGE
    primary-vcc0     primary          5000-5100

VSW
    NAME             LDOM             MAC               NET-DEV   ID   DEVICE     LINKPROP   DEFAULT-VLAN-ID PVID VID                  MTU   MODE  
    primary-vsw0     primary          00:14:4f:fa:40:c8 e1000g0   0    switch@0              1               1                         1500        

VDS
    NAME             LDOM             VOLUME         OPTIONS          MPGROUP        DEVICE
    primary-vds0     primary          base-vol1                                      /dev/zvol/dsk/storage/base/disk0

7. Add a virtual network interface to the new LDOM

 ldm add-vnet vnet1 primary-vsw0 base
