When trying to add nodes of a different version to a grid, you may find an issue with SSL certificates due to a move from legacy to newer RSA CA Certificates. The typical error will display as:
Failed to gather storage system information for remote system
'https://10.42.1.203:5151' [err=SSL_ERROR_SSL error:14094418:SSL
routines:SSL3_READ_BYTES:tlsv1 alert unknown ca ]. [err=5]
In order to fix this, you can either upgrade all nodes to the most recent version. If this is not an option, you can refer to the following shell utilities available on the system. Those commands are:
qs-util cacertuselegacy
qs-util cacertusedefault
You would want to use the first command in order to resolve the issue and once all nodes are upgraded, use the bottom command in order to revert back to the default SSL certificates.
