Sun Cluster 2.2 Deployment Summary

Phase A: [Planing]

Size, Compatibility
Create Disk Groups, Volumes etc.
Determine Private interconnect type & conditions & their IP addresses.
Determine HA (High Available) DATA Services

HA ORACLE
HA-NFS

All entries for all hosts IP addresses & logical host IP (pin-nfs) in /etc/hosts file as well as on DNS (if running).
Determine naming scheme & node info for current situation & for future enhancement.
QUORUM DEVICE selection.
PNM (nafo) settings.
Shared CCD information gathering phase.

Phase B: [Implementation]

Installation Steps

#volcheck
#scinstall ---> Server ---> automatic
~logical host name : automatic
#ssvm
            cluster name = pin-cluster
            node = 2
            type = ether
            node = pin0
            hme0 & hme1 ( default)
                    = ethernet physical address for pin0

pin1
= ethernet physical address for pin1

DATA SERVICE SETUP

HA Data Service = yes ( HA for Oracle)
logical host conf = no ( we'll do it manually)

QUORUM DEVICE SELECTION

Quorum Device : ( select from list)
chosen # 13 ( b/c it is the last disk in the disk array i.e c3t13d0 )

------- >some messages appears here<-------
HA ORACLE....
Sync & Reboot ....

PNM SETTING

#pnmset
    nafo group = 1 ( default )
    backup group = 0 ( default )
    qfe0 & qfe4

#pnmset -p ( for checking purposes )

STARTING CLUSTER ON NODE

#scadmin startcluster pin0 pin-cluster ( single node node 0)
(target)
#scadmin startnode pin-cluster (on node1)
#scconf pin-cluster -S ccdvol
( run above command on both nodes simultaneously. It updates database for CCD)
#confccdssa pin-cluster ( on single node pin0)
( above command manage shared CCD )
#scconf pin-cluster -L pin-nfs -g nfs-dg -n pin0,pin1 -i qfe0,qfe4,pin-nfs -m
( above command is run on single node pin0 . Reboot machines at this stage)

#scconf -F pin-nfs ( manages admin file system. runs on both nodes )

REGISTERING AND STARTING DATA SERVICES
( here it is HA-NFS in our case )

#hareg -s -r nfs -h pin-nfs ( on single node pin0)
(logical host name is pin-nfs)

#hareg
#hareg -y nfs
( this starts data service "nfs")

#scadmin switch pin-cluster pin1 pin-nfs ( on pin0)
