After a recent upgrade to UCS Director 5.4 I noticed that my storage connections were showing a status of failed on the dashboard. I went to Administration -> Physical Accounts -> Physical Accounts. All of my NetApp controllers were offline.
I went to edit settings and re-entered my password to make sure that it had been picked up correctly.
The connection failed with the following error:
500 Connection has been shutdown: javax.net.ssl.SSLHandsakeException:
Server chose SSLv3, but that protocol version is not enabled or not supported by the client.
Well, it seems that the connection now wants to use SSLv3. And I don’t, so we have a bit of a conundrum. I did a search and found that enabling TLS resolves the issue. For more information on TLS check out this Wikipedia page on Transport Layer Security.
Log onto your controller and check the tls options that are currently set.
NetApp_filer> options tls tls.enable off
The next step is to enable TLS using the command below and then check that it has been enabled
NetApp_filer> options tls.enable on
NetApp_filer> options tls tls.enable on
Once that change has been done test the connection once more and it should now appear successfully.
It seems that Cisco changed their authentication method slightly to NetApp storage as part of the 5.4 release.
