We have been using a FAS2750 for years, and since last week with ONTAP 9.15.1P7 (this was necessary because we have acquired a C60 as a successor system and want to transfer the data there soon). As of today, the AIQUM (9.16) that we are using can no longer connect to the FAS2750. Under "Storage Management" / "Cluster Setup" the "Operation State" only shows "failed". Yesterday, a new certificate was issued by the AIQUM and transferred to the FAS2750. Today we also had to issue a new certificate for the AIQUM. This was also transferred to the FAS2750. Could there be a connection? We have already deleted the two newly created certificates on the 2750 and recreated the certificate on the AIQUM using "regenerate", without success.
