I can't change this because the box is grayed out. Is that normal?

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I configured a new vswitch with a service console and a vmkernel to use IPv6 and IPv4. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I can ping the IPv4 address of both the service console and vmkernel. But, I can only ping the IPv4 address of  the service console. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Why would something like that happen? I checked to see if it was a duplicate address and it was not. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt; &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks  &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;It seems that by deleting the second service console and readding it, I can now ping. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt; However, I still can't get the iSCSI initiator to login on an IPv6 address. I have all my IPv6 iSCSI server addresses in the "Send Targets" of the 'Dynamic Discovery' tab. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt; thanks again... &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Is this using vSphere4?  There's no requirement for service console ports to use iSCSI, now.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Can you supply the output of esxcfg-vswitch -l and esxcfg-vmknic -l so I can see what your network config looks like?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Also, are you able to ping the storage from ESX using the vmkping command?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;If you're able to ping both directions, getting logs from the storage and ESX host around discovery time would be the next piece of helpful information.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks,&lt;/P&gt;&lt;P&gt;Andy&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

I just took the service console port out of the virtual switch, but that hasn't made a difference to the iscsi initiator.  &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks!&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Holly&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;

I can't change this because the box is grayed out. Is that normal? Or possiblity the cause of this problem?  &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt; thanks gcshekhar&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Hi, &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I think both ipv6 addresses are local scope at netapp target (&lt;SPAN __default_attr="3" __jive_macro_name="size"&gt;fe80::2a0:98ff:fe0a:1d59&lt;/SPAN&gt;) and esx inititator (&lt;SPAN __default_attr="3" __jive_macro_name="size"&gt;fe80::250:56ff:fe7e:c5d6&lt;/SPAN&gt;) side.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;This  local scope addresses would have problem connecting with tcp/ip without giving a outbound interface, which by default esx sw iscsi would not give.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Netapp side might not be able to route iscsi packets either, if they don't suuport local scope ipv6 initiators, which I'm not sure. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt; (BTW, this does not explain why you can't vmkping from esx to netapp, but it can be the cause of failure of discovery and login iscsi targets) &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;So can you try to config. global scope ipv6 address at both ends?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Regards,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt; - Kun &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
