Unlink the IP and NIC resources. Enter the following:
# hares -unlink ipres nicres
Delete the IP and NIC resources. Enter the following:
# hares -delete ipres # hares -delete nicres
Save your configuration changes. Enter the following:
# haconf -dump -makero
Verify that only IPv6 addresses are defined.
# hares -state | grep -i res #Resource Attribute System Value ipres_v6 State swlx25 ONLINE ipres_v6 State swlx27 OFFLINE nicres_v6 State swlx25 ONLINE nicres_v6 State swlx27 ONLINE
To remove the IPv4 network on the Primary and Secondary sites (optional)
Down the interface on which IPv4 was configured.
# ifdown eth0
Remove the IPv4 network cable. This does not impact replication because the VVR configuration has been migrated to use IPv6 on all sites.
Remove the IPv4 entries from /etc/hosts
and /etc/resolv.conf
files on all the hosts on both the Primary and Secondary sites.
