Planning, GroupWise Design
Agents must be installed on each cluster node Why?? - RPM database issues Log and Startup files are on cluster resource Designate one node as the “install node” Import cluster data to all other nodes Create mount points on appropriate cluster nodes Online resource to “install node” prior to agent configuration Or create a Cluster Resource for Software Distribution Directory - online to node for agent configuration Can create mount point with cluster resource load script “ignore_error mkdir /mnt/mountpoint”

Cluster resource must be online before installation Resource = Cluster volume and secondary IP address Use “install –-cluster” or select Cluster Install on initial dialog Agent install path is hard coded /opt/novell/groupwise/agents Agents must be installed to all appropriate nodes Enter path to cluster resource mount point Log path, startup files point to

Implementation, GWHA
GWHA and GWHA.CONF on each node gwha.conf provides start/stop info for the grpwise script Install has “import clustering data” option Writes all agent config data to gwha.conf on each node Install must be done from a SDD Creates /gwinst/clusterimport.conf
GWMonitor uses GWHA to provide agent restart capabilities in Linux GWMonitor detects if agent is down and issues a restart request to GWHA GWHA configuration
