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 recreate the notifiers.
The stand-alone HP CFS 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 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 3.2 or 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. Chapter 5 describes
how to replace the existing membership partitions.
Back Up the Existing Cluster
Before starting the upgrade, HP strongly recommends that you back up
the following:
The membership partitions. During the upgrade, the new mxds
datastore will be installed on the membership partitions. Although
unlikely, I/O errors during this step could potentially damage a
membership partition, necessitating restoring the original
membership partitions.
Your existing cluster configuration on each server. It is important to
preserve the original cluster configuration in case you need to back
out of the upgrade.
PSFS filesystems. You should have recent backups of all PSFS
filesystems for disaster recovery purposes.
