global cluster

[vucni11]

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?
