Appendix G High Availability
548 September 2002 HPSS Installation Guide
Release 4.5, Revision 2
G.4 Initial Install and Configuration for HACMP
G.4.1 Install HACMP
Install the following file sets from the HACMP 4.4 installation media on each node:
cluster.base
cluster.cspoc
cluster.doc.en_US
cluster.man.en_US
cluster.taskguides
cluster.vsm
G.4.2 Setup the AIX Environment for HACMP
1. Create the /dev/tty<#> devices on each node
2. Setup your SCSI adapters on each node
3. Create the /.rhosts file on each node
This file must contain entries for the service and boot adapters for each node in the cluster
plus one entry for the loopback interface (127.0.0.1). If you have concerns about using the
.rhosts file, refer to page 1-8 of the HACMP for AIX Administration Guide Version 4.4.
An example /.rhosts for our example configuration would be:
hasvc
ha1boot
ha2boot
ha1stby
ha2stby
127.0.0.1
4. Create the /etc/hosts file on each node
This file must contain all node IP interfaces. Since HACMP cannot rely on DNS or NIS to
be available, HACMP operations rely on properly configured /etc/hosts files. For our
example configuration, the file would contain:
127.0.0.1 loopback localhost
192.94.47.156 hasvc
192.94.47.244 ha1boot
192.94.47.69 ha2boot
192.94.48.145 ha1stby
192.94.48.146 ha2stby
5. Configure your boot adapters, standby adapters, and serial adapters
