Dynamically remove CPUs and memory from Ldoms
I 'm tryin to create a new ldom removing 4 vcpus from the existing ldom2 and 4 gb of memory but i get following error

Code:
bash-3.00# ldm rm-vcpu 8 ldom2
VCPU DR disabled because LDom ldom2 has crypto units bound
bash-3.00# ldm rm-mau 7 ldom2
LDom ldom2 is unable to dynamically reconfigure crypto units.
bash-3.00#

Following are my Ldoms detail and Ldom Manager detail

Code:
bash-3.00# ldm -V

Logical Domain Manager (v 1.2)
Hypervisor control protocol v 1.3
Using Hypervisor MD v 1.1

System PROM:
Hypervisor v. 1.7.2. @(#)Hypervisor 1.7.2.a 2009/05/05 19:32\015

OpenBoot v. 4.30.2 @(#)OBP 4.30.2 2009/04/21 09:28
bash-3.00#

Code:
bash-3.00# ldm list
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv- SP 32 16G 0.8% 7d 8h 55m
ldom1 active -n---- 5000 16 8G 0.6% 6d 20h 53m
ldom2 active -n---- 5001 16 8064M 0.1% 20m
ldom3 inactive ------
bash-3.00#

Do i need to do something else to remove the CPU's from the running Ldom ? And is it possible to remove the memory too ?

install-solaris

install-solaris(1M)													       install-solaris(1M)

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
