Recovery

1. This indicates that a MSU was discarded because it failed screening.
   No action is necessary, unless the MSU should have passed. If the MSU should have passed (verified by the fields displayed in the above message), go to 2.
2. Using the rtrv-scr-sio command, verify that the screening reference specified in the above message does not allow MSUs with the SI/H0/H1 values indicated.
3. If the MSU should have passed screening, use the ent-scr-sio command to add the si data to the screening reference assigned to this link.
