Nokia IPSO 4.0 manual Installing Ipso Images, 236

Note

Nokia recommends that you do not make changes to cluster settings or join-time shared features on individual nodes—use Cluster Voyager or the CCLI to make these changes. This will help you ensure that all the nodes are configured consistently.

When you log in as a cluster administrator and change a setting of a join-time shared feature, the change is made across the cluster even if you did not share the feature when you created the cluster. However, systems that join the cluster later do not copy the configuration settings for that feature.

When you make changes to features that you removed from the list of join-time shared features, you see the following message:

This feature is not associated with cluster xxx.

Any changes made would be propagated to all the cluster nodes.

This message is alerting you to the fact that the change will be implemented on all the current nodes but systems that join later will not implement the change.

When you change the time on a node, a message similar to the following appears in the log:

May 24 12:05:09 baston2 [LOG_NOTICE] xpand[803]: date set

May 24 12:07:27 baston2 [LOG_WARNING] kernel: IP Cluster: last keepalive scheduled 530 ms ago

This message is expected and does not indicate that there is any problem.

Note

Some settings of cluster shareable features cannot be configured as a cluster administrator. For example, you cannot use Cluster Voyager to set SSH host and identity keys. To configure these settings, you must log into the individual cluster nodes as a system user.

Installing IPSO Images

Note

You cannot upgrade a cluster directly from IPSO 3.6 to IPSO 3.8 or later. You must upgrade from IPSO 3.6 to IPSO 3.7 and then upgrade to 3.8 or later.

If you want to upgrade a cluster from IPSO 3.7 or later to a later version of IPSO (or revert to the earlier version), Nokia recommends that you use Cluster Voyager to change the IPSO image on all the cluster nodes. To download and install an image in a cluster, follow these steps:

1.On the Cluster Configuration page, click Install New IPSO Image (Upgrade).

2.Use the Cluster New Image Installation (Upgrade) page to download the new IPSO image.
