Upgrade Dell PowerFlex to v3.6.x

PowerFlex GUI upgrade prerequisites

Before upgrading PowerFlex components from all previous versions, ensure that Oracle JRE 1.8 build 301, or OpenJDK JDK 8 build 302.b08, is installed on the server that will host the PowerFlex presentation server. The PowerFlex presentation server is an application that is used from PowerFlex v3.5 and higher. The VxFlex OS GUI client that was used in versions earlier than v3.5 will not be upgraded and is not supported going forward. If the PowerFlex presentation server and the PowerFlex Gateway will be installed on the same server, the PowerFlex Gateway must be installed before the PowerFlex presentation server. The PowerFlex presentation server listens on port 8443, and the PowerFlex Gateway checks that port 8443 is available, although it does not use this port..

For example, install the Oracle JRE file relevant for the server's operating system:

rpm -i /var/tmp/jre-8uXX-linux-x64.rpm
