The IBM iCluster for i™ Portfolio• IBM iCluster for i (5733-ICL) V5R2
– Full featured System i HA– Remote journaling, sync checking, monitoring, alarms and alerts
and switchover– Auto-configuration command for ease of implementation– Scalable from SMB to Large Enterprises
• IBM iBalance for i– Chargeable feature of iCluster– Provides bi-directional HA for workload balancing on CBU Edition– Conflict detection and resolution built in
• IBM LPP – Install through RTSLICPGM– PTFS from PTF Central
© 2009 IBM Corporation
What Happened to iCluster SMB?
• iCluster SMB (5733-ICS)– Introduced in 2007 to address small
and medium business market– Also addressed commoditization of HA
marketplace– Limited to 3 replication groups– Very low pricing
• Challenges:– Lengthened sales cycle due to pre-
qualification– Partners wanted to lead with SMB due
to price point– Customers wanted full functionality of
iCluster at SMB price
– Not aligned with PowerHA

Building Blocks: IBM i Clustering Architecture
Yep! Are you still running?
ProgramRun in case of failure
What does Clustering Do?• Cluster management• Cluster Administrative Domain functions• Heart beating• Facilitates switchovers & failovers • Enables automated application restart and
cluster-enabled applications
What is Clustering?• Defines partitions and applications into
Nodes and Resources Groups (CRG)
• Creates “awareness” of one another for switchover and failover purposes

Key Benefits• Quick Switchover, near real-time for DB• Long distances are realistic• Secondary Copy of Data is available for use – e.g.
Web Query• Helps with Release Upgrades and PTFs• Offline backups with BRMS• Hardware flexibility• Use iCluster for i automation or i CRG• All i releases

What does it Look Like? Auto-configuration
• Why should the customer have to configure the product?• One command creates nodes, journals, sets product values, and creates replication groups and specifiers!• Done in 3 minutes!

Auto Configuration
• Select individual libraries to Primary or Secondary Group or
• PF13 to select everything to Primary Group

Autonomics
• Integrity and readiness of backup via sync checks:
– Dataarea contents– IFS and physical file attributes– Object existence – Physical file contents via hash– Always active sync check
• Reduced administration
– Automatic re-sync of suspended objects
• Increased awareness of HA status:– EMAIL sent for suspended objects and
errors– Alarms and alerts when latency
thresholds exceeded – Monitor indication of refreshes, reorgs,
access path rebuilds files/members

iCluster for i 5.2 Enhancements • Complete integration with IBM i
– iCluster is now installed as a licensed program with licensing by standard IBM i license keys– fixes will be delivered as PTFs– one-stop for Support, with PMRs and APARs to track issues across both iCluster and IBM i.
• Usability– consolidation of multiple sync check types into easy-to-use groupings– consolidated, simplified reports– continuous Sync Check option which always runs as part of mirroring– checking attributes of non-journaled objects– better integration between Sync Check status and auto-recovery (suspension) status.
• Remote journaling performance and recoverability– faster startup when starting from manually set initialization points (set position, mark position).– enhanced recovery option for source system failure – force journal scrape
• Integrated clustering support– ability to configure and interoperate iCluster in pre-existing cluster configurations– easier control of recovery domain upon node failure.

Adding License Keys
• Purchase licenses for every node on iCluster, except in LPAR Box
• Licenses are issued on a machine class basis
• If sent as a file, use ADDLICKEY and prompt PF4 to specify *LICKEYFILE
NOTE: Key specified here is a sample only – use keys specific to your HW

Upgrading from Previous Versions
• Save current iCluster product library DMCLUSTER into a savefile
• Install iCluster 5.2 into ICLUSTER product library
• DMIBMUPGR – mirroring starts from last apply position
