and Clustering GroupWise® 7

• Format– Discussion will be led with supporting examples given

• Questions– Please hold until 'Question Breaks'

• Knowledge:– Advanced GroupWise

– Clustering

– Linux/NetWare®


5

Planning: Definitions and Tools

• Definitions– Consolidation –to reduce/collapse/merge together– Move –to pick up and place in a different location– Upgrade –to increase to a new version– Migrate –to change while moving– Cluster –a bunch of servers gathered round a Storage Area

Network (SAN)– 5 “9's” of Availability (99.999%)

• Tools– Novell® Server Consolidation and Migration Utility– GroupWise® Server Migration Utility– GWCheck– Support.Novell.Com– Forums and Cool Solutions– USB Drive/Planes/Trains/Automobiles– Remote Desktop/VPN/GOTOMYPC.com


6

Planning: Business Analysis

• Reasons to Consolidate?– Old Style Design –Domain, PO, Gateway per remote site

– Faster WAN Links

– Virtualization of Servers

– Decrease Administrative Staff

– Decrease in GroupWise® Administration knowledge

– Centralization of Services to Data centers

– Clustering

– Business Continuance > Disaster Recovery

– Save $$$

Planning: Cluster and GroupWise® Design

• NetWare® Cluster Considerations– LUN's

> SAN's –Support NetWare?

> Proper Carving and LUN Placement

> Naming Standards

– Cluster Nodes> Virtual?

> Naming Standards

– Disk Space> Pools/Volumes

> Naming Standards


10


• More NetWare® Cluster Considerations– Cluster Resources

> Naming Standards –Consider with GroupWise in mind

> IP Address Standards

– Protected Memory

> SET Commands for STARTUP.NCF

> All Agents in own memory space

> Naming Standards

– SLP/HOSTS


11


• Linux Cluster Considerations– Knowledge

– SLES or OES?

– File Systems: Reiser, NSS, EXT3> iManager, NSSMU, EVMS

– LUN's> SAN's –Support OES Linux?

> Proper Carving and LUN Placement

> Naming Standards

– Cluster Nodes> Support OES Linux?

> HBA's support OES Linux?

> Naming Standards


12


• More Linux Cluster Considerations– Disk Space

> Disk Segment

> Volumes

> Mount Points

– Cluster Resources

> Naming Standards –Consider with GroupWise in mind

> IP Address Standards

– SLP


13

Planning: Cluster & GroupWise® Design

• Linux Cluster Installation Tips for GroupWise– 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”> On–line resource to “install node” prior to agent configuration

– Or create a Cluster Resource for Software Distribution Directory – on–line 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”

Questions?


15


• TSATEST– Testing throughput to your SAN and LUN's

– Set a Baseline Test to a local volume

– Set a SAN test to a LUN on the SAN

– Set a Network test to a local volume on a different server

– Create Scripts to run the Commands

16


• NetWare® Scripts– BASETSATEST.NCF

> load tsatest /V=VOL1: /PATH=\TSATTEST /U=.admin.demo /P=novell /I=5 /ERR=sys:\etc\tsaErr.txt

– SANTSATEST.NCF> load

tsatest /V=SANVOL1: /PATH=\TSATTEST /U=.admin.demo /P=novell /I=5 /ERR=sys:\etc\tsaErr.txt

– CROSSTSATEST.NCF> load tsatest /S=FS2 /V=FS2VOL1: /PATH=\TSATTEST /U=.admin.demo

/P=novell /I=5 /ERR=sys:\etc\tsaErr.txt


17


• Linux Scripts– BASETSATEST

> ./tsatest --path={PATH to local disk} -U {USERNAME) -P {PASSWORD} -I 5 --log{=LOGFILE}

– SANTSATEST> ./tsatest --path={PATH to attached SAN disk} -U {USERNAME) -P

{PASSWORD} -I 5 --log{=LOGFILE}

– CROSSTSATEST> ./tsatest -s {SERVER} --path={PATH to local disk} -U {USERNAME) -P

{PASSWORD} -I 5 --log{=LOGFILE}


18


• Virtualization of GroupWise– Yes, you can. Yes it works. Even on a cluster.

– VMware ESX> Virtualize NetWare® and/or Linux

> Virtualize a Cluster of NetWare and/or Linux

– Xen Virtualization> SLES 10 sp1

> SLES Virtual Machine Driver Pack -Windows OS's, RedHat 4,5

> 32 bit/64 bit

> Virtualize NetWare 6.5 sp7 (as part of OES2)

– Not all 'virtualized' servers on 1 VM box

– Test Throughput

– Test Network Throughput

Questions?


20


• Consider the Network Infrastructure

• How are end users going to connect?

– WebAccess/Caching/Online

• Number of Users?

• Number of Post Offices?

• Number of Gateways?

• Document the Design

• Clustering –Use a GroupWise Cluster Design Matrix

Questions?


25

Planning: GroupWise® Audit (Health)

• Current Design– Hub, Mesh, Mixed Topology– Sizing –Users and 'On–Disk data'– Post Offices per Domain– Special Purpose Post Offices –DMS, Resources, etc.– Gateway Usage –POP, IMAP, EMAIL, etc.– Gateways per Domain– Pending Operations– User Move Status per domain, post office– Link Configuration

> TCP/IP

> NOT UNC

> NOT MAPPED


26


• MTA– 2nd Priority Threads

– Bind Exclusively –IP Link Configuration and DNS

– Ports –Standard vs. non–Standard

– Verbose Logging Please

– eDirectory™ User Sync

– /Home–Volume:\directory

– /TCPINBOUND-600+

– /TCPTRUNKWIDTH-4 –NOT anymore!

– Hard configure Ports/IP Addresses???


27


• POA– Bind Exclusively –IP Link Configuration and DNS

– Ports –Standard vs. non–Standard

– Verbose Logging Please

– /Home–Volume:\directory

– Scheduled Events –Contents with “attclip” –Orphaned Attachments –Bye Bye

– Scheduled Events –Structure/Index and Fix

– Hard configure Ports/IP Addresses???

Questions?

Next Up: Implementation


30

Implementation: Move the GroupWise® System

• NetWare® Cluster and the Novell® Server Consolidation Utility

– Make sure SLP is properly configured

– All Servers should have an SMDR entry in SLP

– Make sure HOSTS file is filled in properly

– Stage your move process

> First, move it all at night/weekends (5-20+ hours)

> Second, do delta's to keep the files up-to-date (2.5 to 10+ hours)

> Third, move/cut over (2.5 to 10+ hours)


31

Implementation: Move GroupWise®

• Moving GroupWise from Server to Server

• Connect to Domain being moved OR Post Office Domain

• Change the UNC's –Post Office, Domain, Library Storage (if needed)

• Change the SDD• Change the POA/MTA IP Address,

ports (if needed)• Change the POA/MTA Log

file path• Unload the Agents• Verify 'clean unlocked' status on

DB's (wpdomain and wphost)

• Move the GroupWise component (Domain, Post Office)

• Create new .MTA and .POA configuration files

• Upgrade to new GroupWise version (optional)

• Load the Agents on the new box

• Verify in ConsoleOne®

• Verify on the Agent Screen –F10 Configuration Status, Redirection Links


32

Implementation: Move the GroupWise® System

• Linux Cluster and the GroupWise Server Migration Utility

– Move GroupWise Domains, Post Offices, Gateways– Move from NetWare® and/or Windows to Linux– Not Cluster Aware but Linux server can be member of cluster– Cannot Update to new version of GroupWise while migrating

(unlike with the NW Server Consolidation Utility)– GroupWise 6.5 and 7– Source Servers:

> NetWare 4.2 to 6.5 (OES)> Windows Server 2000 to 2003

– Target Servers:> SLES 8 to 10 (OES)> Red Hat AS, 3 ES

Questions?


34

Implementation: Redesign the GroupWise® System

• Create the New Primary Domain– Link the old Primary to the New Primary– Convert the New Primary to Primary

• Create the New Post Office Domain(s)– Link the New Domain(s) to the New Primary– Do NOT link to the old Domains, until its time to move users

• Create the New Post Offices• Create the Gateway Domains• Create the Gateways• Create Test Users• Test the System• Move Mailboxes


35

Implementation: Move Users Mailboxes

• Why Move Users Mailboxes?– System–wide and Individual user Maintenance and clean up– Database Clean up– Broken, orphaned attachments and Trash left behind

• Move User Formula: Size does matter!!– Estimates of User Mailbox Moves Assumptions

> 15 mins. Average per mailbox> 10 mailboxes moved at the same time, to 20 mailboxes moved at the

same time> 1 person moving all mailboxes

– Example Formula> 400 mailboxes/20 mailboxes moved at 1 time =20 groups of mailboxes> 20 groups x 15 mins. per group =300 mins. > 300 mins./60mins. per hour =5hours.


36


• To Move Users –Preparation– Turn Off Virus Scanners– Unload GWAVA (/vsnoadm)– Contents Check with /attclip Support Option– Turn off Schedule Maintenance– Turn off QuickFinder– Verify/Clear no previous User Move Status from all

domains perspective– Verify/Clear no pending operations– Verify Link Configuration between Source, Destination and Primary

domain are 'Direct, TCP/IP'– Set POA Agent Settings– Message Handler Threads =10 to 20– TCP Handler Threads =10 to 20– Max Thread Usage for Priming and Moves =80/90


37


• To Move Users –Moving– Connect to Destination Domain– Select Source Post Office– Select User to move– Right Click –Move User– View Tools| GroupWise® Utilities| User Move Status– Set POA Logging to Verbose– View Source/Destination POA for Status and Item count

• To Move Resources –Moving– Reassign all Resources to 'temp' user in old post office– Move Resources– Reassign Resources to a 'ResourceMgr' user in the new post

office when asked


38


• F6 –Restart– Monitor the Source/Destination/Primary Domain MTA's

• Problems Seen– Frequent Contacts

– Password reset

– Shared Folders

– Visibility

– Document Management
