Procedure To Configure a Whole Root Zone on Solaris 10

Steps:-

1.Start the zone configuration.

#zonecfg -z wholerootzone, where wholerootzone is the name of the new whole root zone.

Create a configuration for the specified zone.

zonecfg:wholerootzone> create -b

2.Set the zone path.

The zone path must specify a highly available local file system. The file system must be managed by the SUNW.HAStoragePlus resource.

zonecfg:wholerootzone> set zonepath=/global/zones/HA/wholerootzone (Any local filesystem which has enough space to host)

3.Set the autoboot value.

If the autoboot value is set to true, the zone is automatically booted when the global zone is booted. The default value is false.

zonecfg:wholerootzone> set autoboot=false

If resource pools are enabled on the system, associate a pool with the zone.

zonecfg:wholerootzone> set pool=pool_default, where pool_default is the name of the resource pool on the system.

4.Add a network virtual interface.

zonecfg:wholerootzone> add net

5.Set the IP address for the network interface.

zonecfg:wholerootzone> set address=10.255.255.255

6.Set the physical device type for the network interface.

zonecfg:wholerootzone> set physical=hme0

zonecfg:wholerootzone> end

7.Verify and commit the zone configuration.

zonecfg:wholerootzone> verify

zonecfg:wholerootzone> commit

zonecfg:wholerootzone> exit

ldm ls-config    ---> to list sp-config
ldm -V   ---> list the hypervisor version
virtinfo -a   ---> To check control domain name on ldom


Ldom  creation :-
================

ldm add-domain ldom1

ldm ls-domain

ldm add-memory 4g ldom1

ldm add-cpu 8 ldom1

ldm ls-services

ldm ls-services vds0

ldm bind-domain ldom1

ldm set-variable auto-boot\?=false ldom1

ldm start ldom1

telnet 0 5002

Adding zfs data set to LDOM's:
==============================

zfs create -V 25G pool1/ldom1

ldm add-vdsdev /dev/zvol/dsk/pool1/ldom1 ldom1-app@primary-vdso

ldm add-vdisk vdisk2 ldom1-app@primary-vdso ldom1


Adding IsO to control domain:-
=============================


ls /export/home/sol1-10-u10-ga2-sparc-dvd.iso


ldm add-vdsdev options=ro /export/home/sol1-10-u10-ga2-sparc-dvd.iso iso2@primary-vds0


Removing service and domains:-
=============================

ldm stop-domain ldom1

ldm unbind-domain ldom1

ldm remove-domain ldom1


ldm remove-vdisk vdisk1 ldom1
ldm remove-vdisk vdisk ldom1


ldm ls-services

ldm remove-vdsdev ldom1-os@primary-vdso
ldm remove-vdsdev ldom1-app@primary-vdso


LDOM configuration Backup and Restore:-
======================================

ldm ls-config

ldm ls-constraints -x >config .xml

ldm ls-contraints -x ldom1 > ldom1.xml



ldm ls-config

ldm rm-config baseconfig

powercycle
=====================================================================
Once the system has restored to the factory default,then you can restore the system backup using the XML files which we have created.
Login to the control domain and restore it.
=====================================================================

ldm init-system -i config.xml

ldm add-config baseconfig2

#ldm ls-config
factory-default
baseconfig
baseconfig2


ldm init-system -i ldom1.xml -----> only particular ldom restore

ldom add-config baseconfig3
