Chapter 2: Overview 7 Product Changes Affecting the Upgrade Changes Affecting All Upgrades PSFS Filesystem Support for Alternate Data Streams HP Clustered File System 3.6.1 provides filesystem support for Alternate Data Streams (ADS). This support is enabled by default in PSFS filesystems created on HP Clustered File System 3.6.1. To use ADS with an existing PSFS filesystem, you will need to upgrade the filesystem after the upgrade to 3.6.1 is complete.
Chapter 2: Overview 8 Upgrade All Servers As Quickly As Possible It is important to upgrade all nodes in the cluster within a short time frame. We do not recommend running the cluster for an extended period of time with only some of the nodes upgraded to 3.6.1. 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 cluster is only partially upgraded, alerts raised by nodes running 3.
Chapter 2: Overview 9 • 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.
Chapter 2: Overview 10 Back Up the Cluster Configuration The HP Clustered File System service should not be running when you perform the backup. The default location for the cluster configuration files is C:\Program Files\Hewlett-Packard\HP Clustered File System\conf on the drive where you installed HP Clustered File System. Back up the following from the conf directory: • The files directly under \conf • The \conf\debug subdirectory Do not back up the mounts and licenses subdirectories.
3 Rolling Upgrades Overview Rolling upgrades are supported from the HP Clustered File System, and FS Option for Windows 3.4.x and 3.6.0 releases. Custom Installations of HP Clustered File System When you upgrade HP Clustered File System, the Installer looks for the cluster configuration files in the location where HP Clustered File System is currently installed and then applies the configuration files to the new installation. If you perform a custom installation of HP Clustered File System 3.6.
Chapter 3: Rolling Upgrades 12 • The server with the numerically highest primary IP address must be upgraded first. Then continue to upgrade the servers in descending order of IP address, with the server with the lowest primary IP address being upgraded last. • For upgrades from HP Clustered File System 3.4.x, it is important to upgrade all nodes in the cluster within a short time frame. We do not recommend running the cluster for an extended period of time with only some of the nodes upgraded to 3.6.1.
Chapter 3: Rolling Upgrades 13 • During the upgrade, the HP CFS Management Console will show the version of HP Clustered File System that is currently running on the server to which you are connected. Each server will show the currently installed version of the operating system. • The stand-alone Management Console, which is used to connect to the cluster from hosts not running the cluster software, must be upgraded to the 3.6.1 version.
Chapter 3: Rolling Upgrades 14 Rolling Upgrade Procedures The rolling upgrade procedure does not require any cluster downtime. Each server is removed from the cluster, upgraded, and then returned to the cluster. There are two procedures: • Upgrade HP Clustered File System and reinstall the operating system. See page 14. • Upgrade HP Clustered File System without reinstalling the operating system. See page 16.

If you are not prompted to start the service, go to the Cluster Wide Configuration tab and start HP Clustered File System on the upgraded server. The upgraded server will now rejoin the cluster. 18. For each remaining server in the cluster, repeat this procedure through step 12.
4 Non-Rolling Upgrades Overview If you are not performing a rolling upgrade, you can use one of the following methods to upgrade the cluster: • To minimize overall downtime, divide your servers into two groups and then upgrade one group at a time while the other group runs the cluster. This method minimizes downtime. • Upgrade all servers at once. .Upgrades are supported from HP Clustered File System 3.4.0 and FS Option for Windows 3.4.0.
Chapter 4: Non-Rolling Upgrades 21 • If you need to install the 3.6.1 release in a different location, copy the backup configuration files (see “Back Up the Existing Cluster” on page 9) to that location before installing HP Clustered File System 3.6.1. Upgrade Considerations When upgrading HP Clustered File System, you should be aware of the following: • The server with the numerically highest primary IP address must be upgraded first.
Chapter 4: Non-Rolling Upgrades 22 be reported on the Management Console and in the cluster log, and the product will shut down after one hour and 45 minutes. • If a server is temporarily out of the cluster during the upgrade (for example, for maintenance), you will need to upgrade it to 3.6.1 before returning it to the cluster. • If you are upgrading to the 64-bit operating system, be sure to install the 64-bit version of the HBA driver and the 64-bit versions of HP Clustered File System and .
Chapter 4: Non-Rolling Upgrades 23 • After the first server is upgraded to the new operating system and cluster software, restore the cluster configuration directory from backup. • Upgrade all remaining servers, including the server running the older software, and export the cluster configuration to them (as in step 15). To perform the upgrade, complete the following steps. NOTE: Upgrade the server with the highest IP address first.

It can be installed after installing HP Clustered File System. Locate the MxS_Perfmon_3.6.1...msi file on the product CD or in the directory where you downloaded the product and then double-click the file to install it.
Chapter 5: Post-Upgrade Steps 33 Replace Membership Partitions That Are Too Small In HP Clustered File System 3.6, the minimum size for a membership partition has been increased to 1 GB. This change was needed in part to provide room for the new mxds datastore. If an existing membership partition is too small to accommodate the mxds datastore, alert 13914 will be generated: The minimum size for a membership partition is 1GB. The specified partition is too small and should be replaced.
Chapter 5: Post-Upgrade Steps 34 on the filesystem. After the volume and the filesystem are recreated, you can manually restore the data from your backup. To recreate a concatenated dynamic volume, take these steps: 1. Back up the data on the volume. 2. Recreate the dynamic volume. On the HP CFS Management Console, select Storage > Dynamic Volume > Recreate and then choose the volume that you want to recreate. You can change or reorder the subdevices used for the volume if desired.
Chapter 5: Post-Upgrade Steps 35 Upgrade Filesystems for Alternate Data Streams (ADS) HP Clustered File System 3.6.1 provides filesystem support for ADS. This support is enabled by default in PSFS filesystems created on HP Clustered File System 3.6.1. PSFS filesystems created on HP Clustered File System 3.6.0 or earlier releases must be upgraded to enable ADS support. When ADS support is enabled on a filesystem, it cannot be later disabled.
Chapter 5: Post-Upgrade Steps 36 if you have a specific need for these features, as the use of 8.3 files causes degradation in filesystem performance. The degradation is proportional to the number of 8.3 files created. If 8.3 SFN support is later disabled but 8.3 filenames exist, the performance degradation will continue. The filesystem is upgraded with the psfscheck command, which enables the feature internally in the filesystem.
Chapter 5: Post-Upgrade Steps 37 Recreate Notifiers If you previously used notifier scripts, you will need to recreate the notifiers. HP Clustered File System 3.6 provides three event notifier services: • SNMP Notifier Service. This service sends SNMP notifications, or traps, to the configured SNMP targets when the selected events occur. • Email Notifier Service. This service sends email to specified addresses when the selected events occur. • Script Notifier Service.
Chapter 5: Post-Upgrade Steps 38 New Features in HP Clustered File System See the HP StorageWorks Clustered File System Administration Guide for more information about configuring and using these features. • Performance Monitor Service. This service includes two components: the Performance Dashboard and the MxS Perfmon extension. The Performance Dashboard provides server and cluster performance data over a period of time (the last hour, day, week, month, or year).
