IOPn.MtcMon status: An invalid control message was received from IOPx.
Variables x – the ID of the IOP that generated an invalid control message
Severity Error
Description The IOPs frequently exchange messages that are used to monitor and control operations. An
IOP received a control message from a remote IOP that was illegal or invalid for the current
state of the receiving IOP. This message is reported to the Fault Handler, which removes one
of the IOPs from the Endurance server. If the error threshold for the removed IOP is exceeded,
the IOP is faulted until you manually resolve the condition.

Hardware/Software An Endurance server software error that never occurs in an Endurance server using identical
software revisions on both IOPs.
Action • Make sure that the IOPs are using identical revisions of Endurance software.
• Reinstall Endurance software on one or both IOPs to resolve the situation.
• If the condition persists:
- Take and save a crash dump.
- Disable one IOP.
- Boot the Endurance server with only one IOP.
- Contact your service provider to analyze the problem.
