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)

Advantages Disadvantages

EXT3 Advantages Disadvantages

ReiserFS Advantages Disadvantages

Recommendations EXT3 ReiserFS NSS -striped down


Planning, Cluster Design LUNs

SAN's -Support OES Linux? Naming Standards

Cluster Nodes Support OES Linux? HBA's support OES Linux? Naming Standards

Cluster Resources Naming Standards -Consider with GroupWise in mind IP Address Standards

Disk Space Disk Segment Volumes Mount Points

File Systems NSS EXT3 ReiserFS Recommendations

EXT3 ReiserFS NSS -striped down


Planning, GroupWise Design Domain/MTA and Post Office/POA

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 C/S /IP MTPINPORT and MTPOUTPORT


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”


Planning, GroupWise Design

An Example of a “Design Matrix”


Planning, Question Break

Ask'em if you got'em!

?


Implementation, Domain & 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


Implementation, Domain & 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


Implementation, Post Office & 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


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
