Problem Summary: Deleting a public interface group which has both IPv4 and IPv6 enabled adapters sometimes fails when trying to delete the IPv6 adapter from the group. The following error message is displayed :
ifparse: Operation netmask not supported for inet6 /sbin/ifparse /usr/cluster/lib/cmass/ipmpgroupmanager.sh[8]: /etc/hostname.adaptname.tmpnumber: cannot open |
Workaround: Edit the/etc/hostname6.adaptername file to include the following lines:
plumb up -standby |
Run the following command on the cluster node :
ifconfig adaptername inet6 plumb up -standby |
