ClusterPack V2.5 Release Note

Upgrading from V2.3 to V2.5

ClusterPack V2.5 supports an upgrade path from ClusterPack V2.3. Customers that currently

deploy ClusterPack V2.3 on HP Integrity servers use HP-UX 11i Version 2.0 TCOE.

ClusterPack V2.5 provides a mechanism for the use of the majority of V2.3 configuration

settings for the V2.5 configuration.

Before starting the upgrade, it is important to have all of your Compute Nodes in good

working order. All Compute Nodes and MP cards should be accessible. The LSF queues (if in

use) should be empty of all jobs, and the nodes should be idle.

NOTE ClusterPack V2.5 does not integrate with Clusterware Pro. If you are using

Clusterware Pro, the current setup and functionality will not be removed by

ClusterPack V2.5. But, changes made to the cluster configuration (i.e. adding or

removing Compute Nodes, creating groups, etc.) will

NOT be updated

automatically in the Clusterware Pro configuration.

Instructions for upgrading from V2.3 to V2.5:

Step 1. Backup the cluster user-level data.

Step 2. Install the V2.5 backup utilities.

% swinstall -s <depot_with_V2.5> CPACK-BACKUP

Step 3. Take a backup of the cluster information.

% /opt/clusterpack/bin/clbackup -f <backup_file_name>

Copy the backup file to another system for safe keeping.

Step 4. Install the new ClusterPack manager software.

% swinstall -s <depot_with_V2.5> CPACK-MGR

Step 5. Run manager_config in upgrade mode using the file you created in Step 3.

% /opt/clusterpack/bin/manager_config -u <backup_file_name>

Step 6. Register your MP cards. (To save time, check out the new -f option to

compute_config.)

% /opt/clusterpack/bin/mp_register
