ClusterPack V2.5 Release Note

Upgrading from V2.3 to V2.5

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 -foption to compute_config.)

%/opt/clusterpack/bin/mp_register
