Migrating the VCS global clustering service group to IPv6


Migrating the VCS global clustering service group to IPv6
Prev	Migrating to IPv6	Next

To migrate the VCS global clustering service to IPv6, do the following:

Take the ClusterService Group offline on the Primary and Secondary sites.
Edit the VCS configuration for IPv6 addresses.
Bring the ClusterService Group online on the Primary and Secondary sites.

To take the ClusterService Group offline on the Primary and Secondary sites

On the Primary site, enter the following:

# hagrp -offline -force ClusterService -sys swsx25

On the Secondary site, enter the following:

# hagrp -offline -force ClusterService -sys swsx27

To edit the VCS configuration for IPv6 addresses

Make the VCS configuration writeable. Enter the following:
```
# haconf -makerw
```

Modify the following parameters:

haclus -modify ClusterAddress \
  fd4b:454e:205a:111:210:20ff:fe98:0206 -clus sfha_site1
# haclus -modify ClusterAddress \
  fd4b:454e:205a:111:210:20ff:fe98:0205 -clus sfha_site2
# hahb -modify Icmp Arguments \
  fd4b:454e:205a:111:210:20ff:fe98:0205 -clus sfha_site2
# hares -modify gcoip Device bge2
# hares -modify gcoip Address \
  fd4b:454e:205a:111:210:20ff:fe98:0206
# hares -modify gcoip NetMask ""
# hares -modify gcoip PrefixLen 64
# hares -modify gconic Device bge2
# hares -modify gconic NetworkHosts \
  fd4b:454e:205a:111:211:43ff:fed3:f327
# hares -modify gconic Protocol IPv6
# hares -modify gconic Enabled 1

Save your configuration changes. Enter the following:
```
# haconf -dump -makero
```
On the Secondary site, modify the global clustering ClusterServer Group attributes.

To bring the ClusterService Group online on the Primary and Secondary sites

On the Primary site, enter the following:

# hagrp -online -force ClusterService -sys swsx25

On the Secondary site, enter the following:

# hagrp -online -force ClusterService -sys swsx27

The global clustering ClusterService Group in the VCS main.cf configuration file now looks similar to the following:

cluster sfha_site1 (
        ClusterAddress = "fd4b:454e:205a:111:210:20ff:fe98:0206"
        SecureClus = 1
        )

remotecluster sfha_site2 (
        ClusterAddress = "fd4b:454e:205a:111:210:20ff:fe98:0205"
        )

heartbeat Icmp (
        ClusterList = { sfha_site2 }
        Arguments @sfha_site2 = { "fd4b:454e:205a:111:210:20ff:fe98:0205" }
        )

        )

        )

        SystemList = { swsx25 = 0, swsx26 = 1 }
        AutoStartList = { swsx25, swsx26 }
        OnlineRetryLimit = 3
        OnlineRetryInterval = 120
        )

        Application wac (

                MonitorProcesses = { "/opt/VRTSvcs/bin/wac" }
                RestartLimit = 3
                )

        IP gcoip (
                Device = bge2
                Address = "fd4b:454e:205a:111:210:20ff:fe98:0206"
                PrefixLen = 64
                )

        NIC gconic (
                Device = bge2
                NetworkHosts = { "fd4b:454e:205a:111:211:43ff:fed3:f327" }
                Protocol = IPv6
                )

        gcoip requires gconic
        wac requires gcoip
