HCL Workload Automation, Version 9.4

Moving a resource group

You can manually move a resource group to any node in the cluster.

About this task

As the HCL Workload Automation instance user, issue the TWAHome/TWS/TSAMP/moveResourceGroup.sh script. All the resources of the group are stopped, then restarted in the other node of the cluster.

Note: In case of failures, Tivoli System Automation for Multiplatforms automatically moves resource groups.

In a cluster that comprises the master domain manager and backup master domain managers, you can move the following resource groups:

The event processor resource group evtproc-rg
The domain manager resource group dm-rg
The dynamic workload broker resource group broker-rg

In a cluster that comprises the dynamic domain manager and backup dynamic domain managers, you can move the following resource groups:

The domain manager resource group dm-rg
The dynamic workload broker resource group broker-rg

Note: If the domain manager resource group is moved to another node in the cluster, the dynamic workload broker resource group is also moved to the same node, and vice versa.

For example:

$ lssam | grep evtproc
Online IBM.ResourceGroup:evtproc-rg Nominal=Online
        '- Online IBM.Application:evtproc-rs
                |- Online IBM.Application:evtproc-rs:tws1
                '- Offline IBM.Application:evtproc-rs:tws2
$ moveResourceGroup.sh evtproc-rg
Action on resource group "evtproc-rg" returned 
            Token "0x51235c8d17762bfa56b97350bc2d0900".

        '- Pending online IBM.Application:evtproc-rs
