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 willcause one of the nodesto acquire the serviceaddress, vary on theshared 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 http://www4.clearlake.ibm.com/hpss/about/
ServerTable.jsp.However, thereareacouple of extrastepsthat will haveto betaken toensure
that both nodes are installed correctly. Here is the procedure:
1. Installallthesoftwareontheactivenode(thenodewiththeserviceaddress,sharedvolume
groups, and shared file systems).
2. Movethe HPSSresourcegrouptothesecondnode(Refer toSection G.10.5:MoveaResource
Group on page 574).
3. Install allthe softwareon the newly activenode. This is necessarybecause 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
resourcegroupsordoing configurationsmultiple times.Theconfiguration stepsonly affectfiles on
the shared file systems, so proceed as usual.
One thing thatwill need to be doneisto copy the /etc/rc.hpss file to bothnodes.By default, it
will only be copied to the /etc directory of the node that is active when HPSS is being
configured.
