Each VTAM® FFST™ probe can trip up to five times in 5 minutes before it is automatically turned off. Only one of the five dumps will be produced, limiting the number of dumps that you get if a recurring problem triggers a probe.
Depending on how the dump type was coded in the probe, you can get a full dump or an FFST minidump (partial dump). If the dump type is a full dump, only one full dump is created. If the dump type is a minidump, the FFST minidump is created as is a dump containing the last 4 MB of the VIT. For a listing of the dump type for each probe, see First Failure Support Technology (FFST) probes.
