Missing RRD files - Force Recreate Down/Disabled ports

[kiwilad-nz]

The problem

I'm running into an issue on a lot of monitored hosts where I believe RRD files were accidentally deleted by means of testing during issues with unexpected problems arising trying to integrate rrdcached which have since been fixed.

Long story short, RRD files were deleted for ports. Active/Up ports I believe aren't exhibiting this issue and are recreated if missing. However, down and disabled ports that had RRD files generated when 1st added that no longer exists won't get regenerated and really makes it a nuisance when viewing the graphs as it shows errors for every RRD graph that is missing.

The error that makes me believe it is this is this:
eth1118400 skipped because port is still down since last polling.

Is there a way to force create RRD files for ports that are down/disabled across all hosts or at least by specifying hosts?

I've tried different methods but it won't create the missing RRD files:
./poller.php -h PSC_COADMN004AP -d -v
lnms device:poll PSC_COADMN004AP -m ports

I can resolve the issue by either readding the device so that the down ports are also generated upon being added for the 1st time, otherwise I can disable polling on the ports which also resolves the gui from reporting midding RRD files. Either method however is not preferred as I want to retain all other historical data and also want to monitor all ports incase they are later used or recover.
