Directly from the NTP's,
EDD0016 Incorrect data. Dump is inhibited to prevent writing bad data to storage
medium.
Action: Investigate and clear any SYSxxx messages which may appear
concurrently with this message, then attempt to datadump onto a second copy of
the Storage medium.
If EDD016 is printed again, enter the EDD CLR command, then reload from the
new copy to check that data is now valid. If this is done after a reload, the only
further cause would be CED203.
On dual-memory machines, the indicated memory pack should be retested and
reenabled (data will be copied from the other memory). If this fails again (or for
single memory machines), use EDD CLR to dump data to a second copy of the
storage medium, then reload and check any SYS or INI errors for possible data
corruption.
Severity: Critical. Critical to Monitor: Yes. SNMP trap: Yes
