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:
Backup the cluster
user-level data.
Install the V2.5 backup utilities.
% swinstall -s <depot_with_V2.5> CPACK-BACKUP
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.
Install the new ClusterPack manager
software.
% swinstall -s <depot_with_V2.5> CPACK-MGR
Run manager_config in upgrade mode using the file you created in Step 3.
% /opt/clusterpack/bin/manager_config -u <backup_file_name>
Register your MP cards. (To save
time, check out the new -f option to compute_config.)
% /opt/clusterpack/bin/mp_register
Install the new software on the
Compute Nodes. (The -u is important.)
% /opt/clusterpack/bin/compute_config -u
Verify that everything is working
as expected.
% /opt/clusterpack/bin/finalize_config
Printable version
