solaris10 Brand Zone Clusters
Introduction
The solaris10
brand zone cluster, released in Oracle Solaris Cluster version 4.1 software, provides a virtualized Oracle
Solaris 10 cluster environment in an Oracle Solaris 11 configuration. Using this feature enables customers
to run or migrate cluster applications that are deployed on the Oracle Solaris 10 operating system, without
any modification to the application.
The following diagram depicts the coexistence of Oracle Solaris 11 and Oracle Solaris 10
cluster applications, which are isolated by using the zone cluster feature.
Overview of Creating a solaris10 Brand Zone Cluster
You perform the following tasks to create a solaris10
brand zone cluster:
-
Pick a zone image to migrate or install
-
Create an archive
-
Configure the zone cluster
-
Install the zone image for the zone cluster
-
Install the cluster software
-
Boot the zone cluster
-
Log into zone and usage
The following procedure describes these tasks in detail.
How to Create a solaris10 Brand Zone Cluster
Before You Begin
– Ensure that all requirements inPlanning the Oracle
Solaris Cluster
Environment
inOracle Solaris Cluster Software Installation Guide
are met.
1. Pick a zone image to migrate or install.
The archive types that are supported for installing a zone cluster are the following:
-
native
brand zone on an Oracle Solaris10 system -
cluster
brand zone on an Oracle Solaris Cluster node with proper patch level, archive derived from a
physical system installed with Oracle Solaris 10 software -
solaris10
brand zone, archive derived from an installed solaris10
brand zone -
An Oracle Solaris 10 physical system
-
An Oracle Solaris 10 physical cluster node
For more details about support for configuring and installing a solaris10
brand zone cluster, see the Oracle Solaris Cluster 4.1 Release Notes
and How to Create a Zone Cluster in Oracle Solaris Cluster Software Installation Guide .
In this example, an archive is derived from a physical node that is installed with Oracle Solaris 10 software is used with no Oracle Solaris Cluster software installed.
2. Create an archive and store it in a shared location.
For more details about creating archives, see Assessing an Oracle Solaris 10 System and Creating an Archive in System Administration Guide: Oracle Solaris Zones, Oracle Solaris 10 Zones, and Resource Management .
# flarcreate -S -n s10-system -L cpio /net/mysharehost/share/s10-system.flar
This archiver format is NOT VALID for flash installation of ZFS root pool.
This format is useful for installing the system image into a zone.
Reissue command without -L option to produce an archive for root pool install.

3. Configure the zone cluster.
Create and configure the zone cluster, nameds10-zc
in this example, on the global cluster.
The main differences between the solaris
and solaris10
brand zone cluster are setting the brand to solaris10
and adding the sysid
configuration.
4. Install the zone image for the zone cluster.
The zone image is obtained in Step 3.
# clzonecluster install -a /net/mysharehost/share/s10-system.flar s10-zc
5. Install the cluster software.
Perform this steponly
if the archive doesnot
contain cluster software in the image.
a. Boot the zone cluster into Offline/Running mode.
# clzonecluster boot -o s10-zc
b. Access the zone on all nodes of zone-cluster and make sure that system configuration is complete.
# zlogin -C s10-zc
If configuration is not complete, finish any
pending system configuration.
c. From the global zone, check the zone cluster status.
# clzonecluster status s10-zc

d. Install the zone cluster software.
# clzonecluster install-cluster -d /net/mysharehost.com/osc-dir/ \
-p patchdir=/net/mysharehost/osc-dir,patchlistfile=plist-sparc \
-s all s10-zc
-p patchdir
Specifies the location of the patches to be installed along with the cluster software.
patchlistfile
Specifies the file that contains the list of patches to be installed inside the zone cluster along with
the cluster software.In this example, the contents of the fileplist-sparc
are as follows:
# cat /net/mysharehost/osc-dir/plist-sparc
145333-15
Note – Both the patchdir and patchlistfile locations must be accessible to all nodes of the cluster.
-s
Specifies the agent packages that should be installed along with core cluster software. In this example,all
is specified to install all the agent packages.
6. Boot the zone cluster.
a. Reboot the zone cluster to boot the zone into Online/Running mode.
You might have to wait for some time to get
the status to Online/Running.
# clzonecluster reboot s10-zc
b. From the global zone, check the zone cluster status.
The status of zone cluster will now be in
Online/Running mode.
# clzonecluster status s10-zc

7. Log in to the zone and verify the status.
# zlogin s10-zc
[Connected to zone 's10-zc' pts/2]
Last login: Mon Nov 5 21:20:31 on pts/2
# /usr/cluster/bin/clnode status

| zc-host-2 |

Next Steps
The zone cluster configuration is now complete. You can now install and bring up any Oracle
Solaris 10 applications and make them highly available by creating the necessary resources
and resource groups.
