global cluster
Hi,
I like to configure a global cluster.
I have 2 nodes cluster and 1 node cluster.
Cluster clust: test6 and test89 and another cluster with node test5.
In test6 and test89:
root@test89:~# more /etc/llttab
set-node test89 ->set-node test6 in node test6
set-cluster 56482
set-timer sendhbcap:1800
link net1 /dev/net/net1 - ether - -
link net2 /dev/net/net2 - ether - -
link net3 /dev/net/net3 - ether - -
link-lowpri net0 /dev/net/net0 - ether - -
root@test89:~# more /etc/llthosts
0 test6
1 test89
root@test89:~# more /etc/gabtab
/sbin/gabconfig -c -n2
in test5:
root@test5:~# more /etc/llttab
set-node test5
set-cluster 50690
set-timer sendhbcap:1800
link net1 /dev/net/net1 - ether - -
link net2 /dev/net/net2 - ether - -
root@test5:~# more /etc/llthosts
0 test5
root@test5:~# more /etc/gabtab
/sbin/gabconfig -c -n1
I begun the configuration with geoconfig on every cluster.
Enter the Virtual IP address for the Global Cluster Option: ->What is this IP?Is IP of local cluster or IP of remote cluster?
After configuration:
cluster with test89 and test6:
cluster clust (
ClusterAddress = "192.168.114.36"
SecureClus = 1
GuestGroups = { test5 }
UseFence = SCSI3
)
system test6 (
)
system test89 (
)
group ClusterService (
SystemList = { test6 = 0, test89 = 1 }
AutoStartList = { test6, test89 }
OnlineRetryLimit = 3
OnlineRetryInterval = 120
)
Application wac (
StartProgram = "/opt/VRTSvcs/bin/wacstart -secure"
StopProgram = "/opt/VRTSvcs/bin/wacstop"
MonitorProcesses = { "/opt/VRTSvcs/bin/wac -secure"}
RestartLimit = 3
)
IP gcoip (
Device Test6 = net0
Device @test89 = net0
Address = "192.168.114.36"
NetMask = "255.255.255.0"
)
NIC gconic (
Device = net0
)
gcoip requires gconic
wac requires gcoip
cluster with test5
cluster clust5 (
ClusterAddress = "192.168.114.35"
SecureClus = 1
GuestGroups = { test5 }
UseFence = SCSI3
)
system test5 (
)
group ClusterService (
SystemList = { test5 = 0 }
AutoStartList = { test5 }
OnlineRetryLimit = 3
OnlineRetryInterval = 120
)
Application wac (
StartProgram = "/opt/VRTSvcs/bin/wacstart -secure"
StopProgram = "/opt/VRTSvcs/bin/wacstop"
MonitorProcesses = { "/opt/VRTSvcs/bin/wac -secure"}
RestartLimit = 3
)
IP gcoip (
Device test5 = net0
Address = "192.168.114.35"
NetMask = "255.255.255.0"
)
NIC gconic (
Device = net0
)
gcoip requires gconic
wac requires gcoip

To configure remote cluster objects
- Start the Remote Cluster Configuration wizard.
How do i start it?
What is the advantage of using vcs global cluster over disaster recovery cluster where a separate cluster runs on separate site?
In global cluste configuration the service group is up on secondary site faster?
tnx
