How to Move Zone Resources in the N1 Advanced Architecture

This procedure describes how to move a zone resource in the N1 AA web console.

Before You Begin

To move a zone resource, you need to know the resource group for the zone resource that you want to relocate. You can view the resource group by clicking the View All link in the Solaris Non-Global Zone as a Resource section of the SAP plug-in page, then clicking the variable set link for the zone resource.

To successfully move a zone resource to another system, your environment must meet the following requirements.

• The systems involved in the move must be running a Solaris release that supports the Solaris zone attach and detach features. Starting with the Solaris 10 11/06 release, the Solaris zone attach and detach features are supported.

• The systems involved in the move must have compatible file systems, as defined in the zoneadm(1M) man page.

• The systems involved in the move must have the same set of packages and patches installed.

  For more information, see System Administration Guide: Solaris Containers-Resource Management and Solaris Zones.

• The resource group that includes the zone resource must include a High Availability Storage component.

• The High Availability Storage component path must include the zone-specific root path. This path must not terminate at a level above the zone-specific root, or the move will fail. For example, if you are trying to move a zone resource named myzone located in /share/zones, specify the path /share/zones/myzone in the High Availabilty Storage component.

  For more information, see Sun N1 Service Provisioning System User’s Guide for SAP Plug-In 1.0

• The resource group that includes the zone resource must not include a J2EE application server resource.

1. In the N1 AA web console, click the Sun N1 Advanced Architecture for SAP Solutions link in the Systems section.

   The Sun N1 Advanced Architecture for SAP Solutions page is displayed.

2. In the left pane, click the arrow for the appropriate server group.

3. Click the arrow for the Deployer entry for the server group.

4. Click the Resource Groups link.

   The N1AA Deployer - Resource Groups page is displayed.

5. Click the radio button for the resource group that you want to move.

6. In the Action column of the zone resource group, click the Move link.

7. Specify the physical host name of the target host to which you want to move the zone resource.

   The following tasks are performed for the zone resource move.

   • The High Availability Storage device is unmounted from the first host.

   • The non-global zone is detached from the first host.

   • The High Availability Storage device is created and mounted on the target host.

   • The non-global zone is attached on the target host.

Troubleshooting

If the move of the non-global zone fails, verify that the following conditions are true.

• Both systems involved in the move are running a Solaris release that supports the zone attach and detach features. Starting in the Solaris 10 11/06 release, the zone attach and detach features are supported.

• Both systems involved in the move have compatible file systems, as defined in the zoneadm(1M) man page.

• Both systems involved in the move have the same set of packages and patches installed.

• The resource group that includes the zone resource that you want to move includes a High Availability Storage component.

• The resource group that includes the zone resource that you want to move does not include a J2EE application server resource.
