I ran into the issue where i was not able to move the CLUSTER ports from e1a and e2a ahead of time due to not having the PCI card in the FAS8040. Come to find out that the 10gb PCI card in the FAS3240 was not compatible with the FAS8040, so was not able to Move the card over. We had no choice but to proceed, knowing that one of the nodes was going to be OUT OF QUORUM due to these cluster ports. But just wanted to point out to anyone going through this, that the way we got through it was by adding the e0a and e0c ports to the CLUSTER broadcast domain and creating new LIFS in the CLUSTER SVM on both nodes after almost completing the headswap. Waited a couple minutes and both nodes were now in quorum. Verified with the "Cluster Show" and "Cluster ring show" commands. So it is possible to fix up your cluster towards the end of the headswap process.. assuming you follow the instructions correctly and make it that far.Miltherhttps://www.blogger.com/profile/12345576696895310937noreply@blogger.comtag:blogger.com,1999:blog-4270346497183643494.post-77789256670837559202017-06-15T11:56:03.063-07:002017-06-15T11:56:03.063-07:00Hi Christian, yes, 1 cluster port is perfectly fin...Hi Christian, yes, 1 cluster port is perfectly fine. As long as you have one that maps, you're good.

Very nice tests and helpful information.<br /><br />I will do a headswap in this way next week and as far as I understand cDOT and this guide it will be sufficient to have one working cluster-network port (after the swap). I would then migrate the cluster-lif of the port that will disappear (e4a) to a port that will survive (e1a) before I do the swap and that should do the trick and the nodes will be able to form quorum with the two lifs on the single port.<br /><br />Would you agree with that?<br /><br />Kind reagrds<br />ChristianAnonymoushttps://www.blogger.com/profile/04830792036079729357noreply@blogger.com
