The /usr/cluster/lib/cmass/ipmpgroupmanager.sh Script Unplumbs the IPv6 Interface (6174170)

Problem Summary: SunPlex Manager uses the /usr/cluster/lib/cmass/ipmpgroupmanager.sh to delete IPMP groups and adapters from IPMP groups. The script updates the /etc/hostname6.adaptername file correctly to just remove the group name, but runs the following ifconfig command to unplumb the IPv6 interface :

ifconfig adaptername inet6 unplumb

Workaround: Reboot the node to plumb up the interface. Alternatively, run the following ifconfig command on the node. This alternative workaround does not require the node to be rebooted.

ifconfig adaptername inet6 plumb up
