PowerFlex Gateway: UI error ERR_SSL_PROTOCOL_ERROR after GW reinstall

Scenario

The PowerFlex Gateway (GW) was upgraded from version 3.6.0.6 to 3.6.2. After, version 3.6.2 was uninstalled, and version 3.6.0.6 was reinstalled.

The PowerFlex GW UI shows ERR_SSL_PROTOCOL_ERROR after reinstalling the older version, 3.6.0.6.

The Java version was not a factor in this scenario.

Impact

Unable to log in to the PowerFlex GW UI.

PowerFlex Gateway version 3.6.2 introduces new cryptoj libraries that are not compatible with versions earlier than 3.6.2.

SSH to the PowerFlex GW

1. Uninstall the GW rpm

   rpm -e $(rpm -qa |grep -i emc|grep gateway)

2. Move new cryptoj libraries to the /tmp directory.

   find "$(dirname "$(readlink -f "$(which java)")")/../lib/ext" -type f \( -exec rpm -qf {} \; -o -print \) | grep "^/" | xargs -I {} mv {} /tmp/

3. Validate the jar files have been moved to the /tmp directory

   ll /tmp/ | grep jar
   -rwxr-xr-x 1 root root  494856 Sep 23 17:40 commons-lang3-3.6.jar
   -rwxr-xr-x 1 root root 2291434 Sep 23 17:40 cryptoj-6.2.3.jar

   -rwxr-xr-x 1 root root  501115 Sep 23 17:32 sslj-6.5.jar

4. Reinstall the GW

   GATEWAY_ADMIN_PASSWORD='<password>' rpm -ivh /path_to_rpm/EMC-ScaleIO-gateway-3.6-600.113.x86_64.rpm
