IPv6 Link local address
The IPv6 link local address is created automatically from the MAC address
regardless of the availability of the IPv6 address. The array creates the
interface ID which extends the MAC address (48 bits) to the EUI-64 format
(64 bits) and has the address which adds fe80::/10 to the high 64 bits as
the link local address.
Example
If the MAC address is “00:00:87:12:34:56”
1. Split the MAC address by 24 bits “000087” and “123456”
2. Insert
1111 1111 1111 1110 (0xFFFE)
between the split addresses
0000 87FF FE12 3456
3. Reverse the 7th high bits
0200 87FF FE12 3456
4. Add
fe80::/10
to high 64 bits to be the link local address.
fe80::0200:87FF:FE12:3456
Setting the IPv6 address
Hitachi Data Systems recommends that you set the IPv6 address manually.
If you obtain the IPv6 address automatically, since the IPv6 address is
created based on the MAC address, the IPv6 address set to the array is
changed automatically if the control unit is replaced due to a failure, etc. In
this case, you would need to register the array again.
For the range of the IPv6 address set manually, use the global unicast
address
2001::/16
for the IPv6 Internet.
Incorrect router advertisement
A router advertisement daemon (radvd) is run by Linux or BSD systems
acting as IPv6 routers. It sends Router Advertisement messages, specified
by RFC 2461, to a local Ethernet LAN periodically and when requested by a
node sending a Router Solicitation message. These messages are required
for IPv6 stateless autoconfiguration.
When changing the contents of the distributed Router Advertisement,
perform the Router Advertisement (set router lifetime indicating the
expiration date to 0) to disable the previous Router Advertisement from the
Router Advertisement distribution server side. If the Router Advertisement
distribution server side does not disable it, the new Router Advertisement
is received by changing the IPv6 address of the array to the fixed setting
once and changing it to the automatic setting again. When this operation is
completed, since the IPv6 Advertisement of the array is changed, you must
register the array and system again.
