    5. Introduction Presentation Business Topic We will discuss Best Practices for Planning and implementing GroupWise® 7 on Open Enterprise Server Linux. Format Discussion will be led with supporting examples given. Questions Please hold until 'Question Breaks' Knowledge: Advanced GroupWise 7 OES Linux Related Sessions: Consultants Corner: Successful GroupWise 7 Consolidations The Art of Business Continuance

    6. Open Enterprise Server LX Cluster Planning Definitions and Tools Definitions Cluster - A group of servers and a SAN Node - A server in a cluster LUN's - Logical Unit Number (Disk Space on a SAN) Cluster Resource - Virtual Server - not NSS only in Linux Design Matrix – Planning data OES Linux/SUSE® Linux Tools ConsoleOne® *NEW* Migration Kit for NetWare® to Linux iManager Novell Remote Manager (NRM)

    7. Open Enterprise Server LX Cluster Planning Definitions and Tools File Systems NSS Advantages Disadvantages EXT3 Advantages Disadvantages ReiserFS Advantages Disadvantages

    9. Open Enterprise Server LX Cluster Planning Our Company

    10. Open Enterprise Server LX Cluster Planning Cluster Design LUN's SAN's -Support OES Linux? Naming Standards Cluster Nodes Support OES Linux? HBA's support OES Linux? Naming Standards Disk Space Disk Segment Volumes Mount Points Cluster Resources Naming Standards -Consider with GroupWise® in mind IP Address Standards

    11. Open Enterprise Server LX Cluster Planning GroupWise® Design Domain and MTA What information is needed to cluster a Domain and MTA? Naming and Numbering Standards Cluster Resource Names-Consider in Cluster Planning Volume Names Directory Paths IP Addresses Ports MTP HTTP

    12. Open Enterprise Server LX Cluster Planning GroupWise® Design Post Office and POA What information is needed to cluster a Post Office and POA? Cluster Resource Name Volume Name Directory Path IP Address Ports C/S /IP MTPINPORT and MTPOUTPORT HTTP

    13. Open Enterprise Server LX Cluster Planning GroupWise® Design Gateways - GroupWise Internet Agent New Alternate GWIA failover for MTA's Must be on same resource as owning domain Create an A record for secondary IP address point MX record to the A record Set Bind Exclusive to TCP/IP address Yes, it binds for all protocols! Leave Postfix running listening on loopback address (default)

    14. Open Enterprise Server LX Cluster Planning GroupWise® Design

    15. Open Enterprise Server LX Cluster Planning GroupWise® Design

    17. Open Enterprise Server LX Cluster Planning GroupWise® Design GroupWise Design Matrix

    18. Open Enterprise Server LX Cluster 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” Online resource to “install node” prior to agent configuration Or create a Cluster Resource for Software Distribution Directory - online to node for agent configuration Import cluster data to all other nodes Create mount points on appropriate cluster nodes Can create mount point with cluster resource load script “ignore_error mkdir /mnt/mountpoint”

    19. Implementation – File System File systems NSS Create pool identical to NetWare® cluster use iManager or NSSMU Native Linux File Systems Must uses EVMS to create containers and volumes See TID 3003435 for details and requirements remove existing segment manager create container create volume create file system

    20. Implementation – File System

    21. Implementation – File System Native Linux File Systems Create cluster resource manually Use iManager Create using Generic IP template Use script from TID 3003435 to activate/deactive the container Test online/offline of resource before GroupWise® install

    22. Implementation Domain and MTA 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 <mountpoint>/opt/groupwise/share

    23. Implementation Domain and MTA Loading the MTA /opt/novell/groupwise/agents/bin/gwmta @/<mntpoint>/groupwise/agents/share/utah.mta /etc/init.d/grpwise start utah Unload the MTA /etc/init.d/grpwise stop utah Edit Cluster load/unload scripts Test the Cluster Resource

    24. DEMO TIME!!!

    25. Questions and Answers

    26. Implementation Post Office and POA Configure the Cluster Resource Load Script Unload Script Fail Over Loading the POA /opt/novell/groupwise/agents/bin/gwpoa @/<mntpoint>/groupwise/agents/share/provo.poa /etc/init.d/grpwise start provo.utah Unload the POA /etc/init.d/grpwise stop provo.utah Edit load/unload scripts and test the Cluster Resource

    27. DEMO TIME!!!

    28. Questions and Answers

    29. Implementation GroupWise® Internet Agent Install and configure to GWIA's owning domain node Set TCP/IP address to secondary IP address Set Bind Exclusive Loading GWIA /opt/novell/groupwise/agents/bin/gwgwia @/<mntpoint>/groupwise/agents/share/gwia.cfg /etc/init.d/grpwise start utah.gwia telnet to port 25 to validate SMTP Listener add GWIA load command to Domains cluster load/unload scripts

    30. DEMO TIME!!!

    31. Questions and Answers

    32. 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 xinetd service – disabled by default Protect using SSL modify /etc/init.d/grpwise-ma script to enable HA polling.

    33. DEMO TIME!!!

    34. Summary Protected Memory Not on Linux Registering to the Nodes (RPM) Designed to run agents in daemon mode Cluster Command line options cluster offline <resource> cluster online <resource> <node> cluster migrate <resource> <node> cluster status Or use iManager Novell Clustering Services™ logging events in /var/log/message No Agent Screens loaded on nodes by default
