Oracle Grid Infrastructure Configuration Issue
If any of the Microsoft Failover Cluster Virtual Adapter and Tunnel Adapters
(Microsoft ISATAP, 6to4, Teredo) are enabled, the grid installation
configuration fails as MDNSD is unable to register on the network adapter
with Invalid mask.
The following error message is displayed:
INS-20802 and error ORA-29783: GPnP attribute SET
failed with error [CLSGPNP_RD_ERR] in asmca log
Disabling IPv6 for the Network Adapters
IPv6 is not certified with grid infrastructure and should be disabled before
installing the grid infrastructure.
To disable IPv6 on all the nodes:
1
Disable Microsoft failover cluster adapter and all tunnel adapters from the
Device Manager (
View → Show hidden devices ) before installing
Oracle11g R2 grid infrastructure.
2 Open regedit and back up registry.
3 Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\Tcpip6\Parameters\
.
4 Double-click DisabledComponents to modify it.
5 If there is no DisabledComponents entry, create it by opening the Edit
menu.
6 Select New → DWORD (32-bit) Value and type
DisabledComponents and press <Enter>.
7 Add DWORD with the value: 0xffffffff.
This disables all IPv6 components, except the IPv6 loopback interface.
