3.6.0 Matrix Server Upgrade Guide (5697-7085, February 2008)

Chapter 2: Overview 4

Upgrade Considerations

Several product changes in Matrix Server 3.6.0 and MxDB for SQL Server

3.6.0 affect the upgrade procedure. Be sure to review the following

information before starting the upgrade.

Upgrade All Servers As Quickly As Possible

It is important to upgrade all nodes in the matrix within a short time

frame. We do not recommend running the matrix for an extended period

of time with only some of the nodes upgraded to 3.6.0. This release

introduces a new configuration data repository and a new logging facility

that do not become fully functional until all nodes are upgraded. If the

matrix is only partially upgraded, alerts raised by nodes running 3.6 will

be improperly logged by nodes running 3.4. Also, until the entire matrix

is upgraded, many services that are run on 3.6 nodes must be run as local

system administrator.

Matrix Server Changes

You should be aware of the following changes:

• Concatenated dynamic volumes. If your matrix configuration includes

concatenated volumes, we recommend that you recreate them after

completing the Matrix Server upgrade. (The volumes can continue to

be concatenated when they are recreated.) The volume disaster

recovery feature cannot be used with a concatenated dynamic volume

that has not been recreated. Striped dynamic volumes are

automatically upgraded to use the new feature during the 3.6

upgrade.

• Notifiers. The built-in notifiers provided with previous releases of

Matrix Server are no longer supported. Existing notifiers will continue

to function until the last server is upgraded. At that point, the notifiers

will be deleted from the configuration. If you are currently using

notifiers, be sure to back up your notifier scripts. After the upgrade is

complete, you will need to recreate the notifiers.

• The stand-alone PolyServe Management Console provided with the

3.2 and 3.4 releases cannot be used to access a node running 3.6.0. You

will need to upgrade the stand-alone console after the Matrix Server
