Netapp Collect: Unable to match key signature algorithm

    What versions of NetApp are you running? This message indicates these arrays are very old. We do not support the SSH algorithm being passed back to the collector so we cannot proceed. .

    I will get that info.  I believe that one was a newer CDot array, here is a second one.  FIPS is on and all but AES ciphers are disabled.  Hoping you can help with some ideas!  Thanks.

    Paul, I'm going to go ahead and convert this to a ticket.  You should get an email confirming.  Thank you, David.
