An online migration of the VCS global clustering service group is not supported. Put the service group offline and then modify the required parameters.
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
# hagrp -offline -force ClusterService -sys node_name
For example, on the Primary site, enter the following:
# hagrp -offline -force ClusterService -sys swlx25
On the Secondary site, enter the following:
# hagrp -offline -force ClusterService -sys swlx27
To edit the VCS configuration for IPv6 addresses
# haconf -makerw
# haclus -modify ClusterAddress \ fd4b:454e:205a:111:213:72ff:fe5b:2f67 -clus sfcfs_gco1 # haclus -modify ClusterAddress \ fd4b:454e:205a:111:211:43ff:fede:1e11 -clus sfcfs_gco2 # hahb -modify Icmp Arguments \ fd4b:454e:205a:111:211:43ff:fede:1e11 -clus sfcfs_gco2 # hares -modify gcoip Address \ fd4b:454e:205a:111:213:72ff:fe5b:2f67 # hares -modify gcoip Enabled 1 # hares -modify gcoip PrefixLen 64 # hares -modify gcoip NetMask "" # hares -modify gcoip Device eth1 # hares -modify gconic Device eth1 # hares -modify gconic Enabled 1
# haconf -dump -makero
To bring the ClusterService Group online on the Primary and Secondary sites
# hagrp -online ClusterService -sys node_name
For example, on the Primary site, enter the following:
# hagrp -online -force ClusterService -sys swlx25
On the Secondary site, enter the following:
# hagrp -online -force ClusterService -sys swlx27
The global clustering ClusterService Group in the VCS main.cf
configuration file now looks similar to the following:
cluster sfcfs_gco1 ( ClusterAddress = "fd4b:454e:205a:111:213:72ff:fe5b:2f67" SecureClus = 1 HacliUserLevel = COMMANDROOT ) remotecluster sfcfs_gco2 ( ClusterAddress = "fd4b:454e:205a:111:211:43ff:fede:1e11" ) heartbeat Icmp ( ClusterList = { sfcfs_gco2 } Arguments @sfcfs_gco2 = { "fd4b:454e:205a:111:211:43ff:fede:1e11" } ) system swlx20 ( ) system swlx21 ( ) group ClusterService ( SystemList = { swlx20 = 0, swlx21 = 1 } AutoStartList = { swlx20, swlx21 } OnlineRetryLimit = 3 OnlineRetryInterval = 120 ) Application wac ( StartProgram = "/opt/VRTSvcs/bin/wacstart" StopProgram = "/opt/VRTSvcs/bin/wacstop" MonitorProcesses = { "/opt/VRTSvcs/bin/wac" } RestartLimit = 3 ) IP gcoip ( Device = eth1 Address = "fd4b:454e:205a:111:213:72ff:fe5b:2f67" PrefixLen = 64 ) NIC gconic ( Device = eth1 ) gcoip requires gconic wac requires gcoip
