[Linux-PowerEdge] IPv6 vs iDRAC7 vs ipmitool

Hi all,

After the great help I received here yesterday, I have high hopes for this
one as well

I have enabled IPv6 on a set of iDRACs, and can ping6 them or ssh into them
using the v6 address.

However, ipmitool fails to connect completely. Below are some command
outputs using ipv4 and ipv6 addresses of the same DRAC (R320/iDRAC7-ENT in
this case):

$ ping -6 2620:52:0:13b8:46a8:42ff:fe3b:235f
PING 2620:52:0:13b8:46a8:42ff:fe3b:235f(2620:52:0:13b8:46a8:42ff:fe3b:235f)

64 bytes from 2620:52:0:13b8:46a8:42ff:fe3b:235f: icmp_seq=2 ttl=64

$ ping
PING ( 56(84) bytes of data.
64 bytes from icmp_seq=1 ttl=64 time=0.755 ms
64 bytes from icmp_seq=2 ttl=64 time=0.488 ms

$ ipmitool -I lanplus -H -U root -R 3 -N 5 -P calvin power
Chassis Power is on

$ ipmitool -I lanplus -H 2620:52:0:13b8:46a8:42ff:fe3b:235f -U root -R 3 -N
5 -P calvin power status
Error: Unable to establish IPMI v2 / RMCP+ session

^^ this after waiting for a minute or so, so something is definitely

ssh root at 2620:52:0:13b8:46a8:42ff:fe3b:235f
root at 2620:52:0:13b8:46a8:42ff:fe3b:235f's password: ****

In short, I do have connectivity, but I wonder whether there's something
else to enable on the iDRAC, to allow ipmi over ipv6
