2.7.4.2 Issues Causing a Change to the InForm Configuration
The following issue causes a change to the InForm configuration when downgrading from
InForm OS release 2.3.1 or 2.3.1 MU2.
■ Host Personas - If a system running InForm OS release 2.3.1 MU2 is downgraded, host
persona fields are cleared and the old port persona settings resume effect. However, these
settings are not kept up-to-date nor are they converted back on downgrade, so they will
not reflect any configuration changes made since loading 2.3.1 MU2. On a system which
only ran 2.3.1 MU2, there will be no port persona settings to revert to.
Prior to the downgrade, a check is run to ensure the system can run in the downgraded
state. If host persona specific configurations are detected, a message is issued. This
condition will need to be resolved before the downgrade is permitted. One example of this
would be different host persona settings sharing a port which can not be supported via
port personas.
