Upgrade guide for UNIX missed the step to copy license file (<snapcreatorinstallation_directory>/LICENSE) from backup to new installation location. So after the upgrade step, when I was starting snap
creator server (<snapcreatorinstallation_directory>/bin/scServer start), it was giving this error: "Please run ./snapcreator --setup first." I copied LICENSE file and this fixed the issue.
Later I encountered this error when running test backup:
[2016-04-24 20:38:07,088] ERROR: STORAGE-03033: Getting system version details of [vpsafiler01] failed with error [javax.net.ssl.SSLException: Connection has been shutdown: javax.net.ssl.SSLHandshakeException: Server chose SSLv3, but that protocol version is not enabled or not supported by the client.]
I fixed it by disabling sslv2 and sslv3 and enabling tls on storage. I followed KB Doc ID 2022799 for this.
