On the Novell Modular Authentication Service page, click Next.
Continue with Specifying LDAP Configuration Settings.

Specifying LDAP Configuration Settings

Many of the OES services require eDirectory. If eDirectory was not selected as a product to upgrade or install but other OES services that do require LDAP services were installed, the LDAP Configuration service displays so that you can complete the required information.

In the eDirectory Tree Name field, specify the name for the existing eDirectory tree that you are installing this server into.
In the Admin Name and Context field, specify the name and context for user Admin on the existing tree.
In the Admin Password Name field, specify a password for user Admin on the existing tree.
Add the LDAP servers that you want the services on this server to use. The servers that you add should hold the master or a read/write replica of eDirectory. Do the following for each server you want to add:
1. Click Add.
2. In the next dialog box, specify the following information for the server to add, then click Add:
  - Server IP Address
  - LDAP port
  - Secure LDAP port
3. Click Add.
4. (Optional) Repeat Step 4.a through Step 4.c to add additional servers.
When all the LDAP servers that you want to specify are listed, click Next.
Continue with Configuring Open Enterprise Server Services.

Configuring Open Enterprise Server Services

After you complete the LDAP configuration or eDirectory configuration, the Open Enterprise Server Configuration summary page is displayed, showing all the OES components you updated and installed and their configuration settings.

Review the setting for each component and click the component heading to change any settings.

When you specify the configuration information for OES services, see the information in Configuration Guidelines for OES Services, or click a link below:
When you are satisfied with the settings for each component, click Next.
When you confirm the OES component configurations, you might receive the following error:

The proposal contains an error that must be resolved before continuing.

If this error is displayed, check the summary list of configured products for any messages immediately below each product heading. These messages indicate products or services that need to be configured. If you are running the YaST graphical interface, the messages are red text. If you are using the YaST text-based interface, they are not red.

For example, if you selected Linux User Management in connection with other OES products or services, you might see a message similar to the following:

Linux User Management needs to be configured before you can continue or disable the configuration.

If you see a message like this, do the following:
1. On the summary page, click the heading for the component.
2. Supply the missing information in each configuration page.
  
  When you specify the configuration information for OES services during the upgrade, see the information in Configuration Guidelines for OES Services.
  
  When you have finished the configuration of that component, you are returned to the Novell Open Enterprise Server Configuration summary page.
3. If you want to skip the configuration of a specific component and configure it later, click Enabled in the Configuration is enabled status to change the status to Configuration is disabled.
  
  If you change the status to Configuration is disabled, you must configure the OES components after the installation is complete. See Installing or Configuring OES Services on an Existing OES Server.
After resolving all product configuration problems, click Next to proceed with the configuration of all services and installation of iManager plug-ins.
When the Readme page displays, click Next and continue with Section 5.4.10, Finishing the Upgrade.

5.4.9 Participating in Product Improvement Consent Screen

Telemetry enables to collect statistical data about your usage of services on the OES server. This data enables us to ensure that you have the best possible experience with OES services. Weekly once the data is sent to the Micro Focus server.

Select the checkbox to participate in the program. All the servers in the same context as this server are automatically enabled for telemetry and this screen is not displayed to other servers in that context.

Figure 5-1 Product Improvement

How the Micro Focus Server Receives the Data

After the weekly collection, the data is stored at /var/opt/novell/telemetry/data/ on the OES server that was configured with this program. The OES server transfers the data to the Micro Focus server. If the transfer is unsuccessful, the system attempts to send it again during the next weekly cycle. No attempts to send the data is made outside of the weekly cycles.

The data is not encrypted because no sensitive or identifying information is included.

5.4.10 Finishing the Upgrade

After a successful configuration, YaST shows the Installation Completed page.

Deselect Clone This System for AutoYaST. Cloning is selected by default.

This increases the speed of finishing the installation update.

AutoYaST is a system for automatically installing one or more SUSE Linux Enterprise systems without user intervention. Although you can create a profile from a system that has been upgraded, it does not work to upgrade a similar system.
Finish the upgrade by clicking Finish on the Installation Completed page.

5.4.11 Migrating Clustered Linux Volume Resource from clvmd to lvmlockd

Beginning with OES 23.4, clustered Linux volume (LV) uses the lvmlockd instead of clvmd as it is deprecated.

Without performing the following step, if the clustered linux volume is migrated to OES 23.4 the clustered Linux volume resources will go to comatose state.

Migrating clustered Linux volume resource from clvmd to lvmlockd consists of the following steps:

Changing the clvmd resource to local resource.
Changing the clustered Linux volume to use lvmlockd from clvmd.

NOTE:After performing the above steps, if the clustered Linux volume is migrated to previous OES version node, then the clustered Linux volume resources will go to comatose state.

Changing clvmd Resource to Local Resource

You must perform the following steps on a node where cluster resource is running:

Ensure the clvmd resource is not running on any node. For more information, see Onlining and Offlining (Loading and Unloading) Cluster Resources from a Cluster Node.
Change the clustered volume group (VG) to a local VG.

vgchange -cn <vgname>

Changing Clustered Linux Volume to use lvmlockd from clvmd

Ensure the clvmd or clustered VG to a local VG.

vgchange --lock-type none --lock-opt force <vgname>

CAUTION:This command is only safe if all the nodes have stopped using the VG.
Deactivate the logical volume on OES 23.4 server.

lvchange -an <lvname/vgname>
Change a local VG to a shared VG.

vgchange --config "global/use_lvmlockd=1" --locktype sanlock --lockopt skipgl <vgname>

If this command succeeds, go to Step 6.
If Step 3 fails with an error "Volume group "VGNAME" has insufficient free space (0 extents): 64 required" then complete the following:
1. Activate the logical volume.
  
  lvchange -ay <lvname/vgname>
2. Resize the volume using lvreduce command.
  
  Example: lvreduce --resizefs -L <new volume size> <vgname>
3. Deactivate the logical volume.
  
  lvchange -an <lvname/vgname>
Repeat Step 3 if you have executed Step 4.
Update the load and unload script for the clustered resource.
1. Add the following command in cluster load script before activating the volume group:
  
  ignore_error vgchange --lock-start $VOLGROUP_NAME
  
  Example
  
  # activate lvm-lock on volume
  
  ignore_error vgchange --lock-start $VOLGROUP_NAME
  
  # activate the volume group
  
  exit_on_error vgchange -a ey $VOLGROUP_NAME
2. Add the following command in cluster unload script after deactivating the volume group:
  
  ignore_error vgchange --lock-stop $VOLGROUP_NAME
  
  Example
  
  # deactivate the volume group
  
  exit_on_error vgchange -a en $VOLGROUP_NAME # deactivate lock on volumes
  
  ignore_error vgchange --lock-stop $VOLGROUP_NAME
Make the cluster resource available on the OES 23.4 server.
