The backup cws has to be installed with the same level of AIX and PSSP. Depending on the kerberos configuration of the primary cws, the backup cws has to be configured either as a secondary authentication server for the authentication realm of your RS/6000 SP when the primary cws is an authentication server itself, or as an authentication client when the primary cws is an authentication client of some other server. To do so will enable a correct kerberos environment on the backup cws; so, remote commands will succeed through kerberos authentication as on the primary cws.
After the initial AIX and PSSP setup is done, the HACWS software has to be installed.

On both control workstations, the HACMP software has to be installed now, according to the instructions in the HACMP for AIX, Version 4.3: Installation Guide,
9.1.5 HACWS Configuration
Since the cws might have some daemons active that could interfere with the definition and configuration of networks, you have to stop them, in order to get the configuration done, with the command:
/usr/sbin/hacws/spcw_apps
This will stop the subsystems spmgr splogd hardmon sysctld supfilesrv
sp_configd if they have been active with the corresponding SRC command.
Now configure the serial network. You can either use target mode SCSI, target mode SSA or the raw
Both machines, primary and backup, need to be configured to boot up on their boot address in order to not confuse a working cws at boot time of the backup cws.
If not previously done, you have to migrate the /spdata file system to an external volume group, to make it accessible from both sides.
After the /spdata file system is set up so that a varyonvg of its vg will work on either cws, you have to complete the Administration Tasks, like on an
