VNX: How to manually assign an IPv6 address to a VNX2 block array

In order to manually set up IPv6 configuration (including Gateway) you need the IPv6 address for both SP's and the link-local GW address.

From R33.119 release notes:

"Support for IPv6 configurability

For Block-only systems, the main enhancement for Block-only SPs is the ability to customize all 128-bits of the IPv6 address using the naviseccli command-line interface. In addition, some IPv6 settings can be enabled, disabled, or set from the Unisphere GUI interface.

Use the following naviseccli example to custom configure all 128-bits of the IPv6 address:

/nas/sbin/naviseccli -h networkadmin -set -ipv6 -manual -address 3ffe:80c0:22c:4c:1319:8a2e:370:7348 -gateway fe80::21e:67ff:fe6a:50a9"

Note that the format of the GW address is link-local, if you try to put in the full IPv6 address the command will fail with:

"Invalid command line parameters: -gateway <full GW IPv6 address>
The gateway must be an IPv6 link-local address."


Configuration Steps:

1. Confirm that IPv6 is currently disabled, this can be done in two ways:

          - GUI, Settings > Edit Network Settings - SPA > Click on Virtual Port 0 properties > Network tab
          - CLI, run naviseccli networkadmin -get -all 

2. To obtain the IPv6 link-local GW address, from the Network tab of the Virtual Port 0 properties set IPv6 Configuration to Automatic. This will restart the management server, once it restarts the Network tab will contain the link-local GW address, record this.

3. Disable IPv6 either from the GUI or with:
 
naviseccli networkadmin -set -ipv6  disable

4. The following command can then then be used to assign the IPv6 address and GW, this will again restart the management server on the SP the command is run against:

naviseccli networkadmin -set -ipv6 -manual -address <SP IPv6 address> -gateway <IPv6 link-local GW address>


Note that for any other array in the same network the same link local GW IP can be used.
