G.4.4 Configure DCE, SFS, and HPSS
G.4.4.1 Start the Cluster
To continue configuring DCE, Encina, and HPSS, it will be necessary to start the HACMP cluster.
This will cause one of the nodes to acquire the service address, vary on the shared volume groups,
and mount the shared file systems.
For information on how to start cluster, see Section G.10.1: Startup the Cluster on page 570.
G.4.4.2 Install Shared Software
Now that the cluster is up and running, it is possible to install DCE, SFS, Sammi, HPSS, and any
other software that must reside on the shared disks (i.e. Java). To determine versions, refer to the
HPSS Compatibility Chart at
ServerTable.jsp. However, there are a couple of extra steps that will have to be taken to ensure
that both nodes are installed correctly. Here is the procedure:
1. Install all the software on the active node (the node with the service address, shared volume
groups, and shared file systems).
2. Move the HPSS resource group to the second node (Refer to Section G.10.5: Move a Resource
Group on page 574).
3. Install all the software on the newly active node. This is necessary because not all installed
files reside on the shared disks. In order to get these locally stored files properly installed
on both nodes, a second complete install of all software must be performed on both nodes
4. Move the HPSS resource group back to the original node.
G.4.4.3 Configure HPSS As Usual
Now that all the software is properly installed, configuration may proceed as usual starting with
Chapter 5: HPSS Infrastructure Configuration (page 215). There is no need to worry about moving
resource groups or doing configurations multiple times. The configuration steps only affect files on
the shared file systems, so proceed as usual.
One thing that will need to be done is to copy the /etc/rc.hpss file to both nodes. By default, it
will only be copied to the /etc directory of the node that is active when HPSS is being
configured.
