Chapter 2: Upgrade procedure 5
HP Clustered File System Changes
You should be aware of the following changes:
• Concatenated dynamic volumes. If your cluster configuration
includes concatenated volumes, we recommend that you re-create
them after completing the HP Clustered File System upgrade. (The
volumes can continue to be concatenated when they are re-created.)
The volume disaster recovery feature cannot be used with a
concatenated dynamic volume that has not been re-created. 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 HP
Clustered File System 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 re-create the notifiers.
• The stand-alone HP CFS Management Console provided with the 3.4
release cannot be used to access a node running 3.6.0. You will need to
upgrade the stand-alone console after the HP Clustered File System
upgrade. (The stand-alone HP CFS Management Console provided
with the 3.6 release is backward-compatible and can access nodes
running HP Clustered File System 3.4.)
• HP Clustered File System now uses single sign-on authentication. The
admin user, the mxpasswd file, and the mxpasswd command are now
obsolete.
• The minimum size for a membership partition is now 1GB. If your
existing membership partitions are too small to accommodate the new
mxds datastore, which is included in the membership partitions, an
alert will be generated after the upgrade to 3.6. "Changes necessitated
by upgrade" section describes how to replace the existing membership
partitions.
