Chapter 50 MEU (Maintenance Entity Unit) Messages

Cause  The MEU started its initialization phase due to maintenance server power-on or reset.

Effect  Additional MEU events are expected to subsequently track the completion of the MEU initialization phase and the completion of the overall MEU application start-up.

Recovery  Informational message only; no corrective action required.

Cause  If the MEU finds a valid Subnet Database then its state will be NORMAL, otherwise its state will remain AWAITING_CONFIG.

Effect  An MEU in the NORMAL state is fully functional. An MEU in the AWAITING_CONFIG state is only minimally functional. To transition an MEU from the minimally functional to the fully functional state requires that an external client create or activate a valid Subnet Database.

Recovery  If the MEU state is AWAITING_CONFIG then use the OSM System Configuration Tool to create or activate a valid Subnet Database.

Cause  A CPU changes state.

Effect  The CPU changes to the new state.

Recovery  If the CPU state change is expected, then this is an informational message and no recovery is required. If however the CPU state change is unexpected, then see the Processor Halt Codes manual and perform the recovery listed for the particular halt code or contact HP support for assistance.

Cause  The MEU application completed its initialization phase.

Effect  The MEU’s state is set and will remain so until either an external client changes it, or the CLIM is restarted.

Recovery  Informational message only; no corrective action required.

Cause  This event is generated daily by each MEU.

Effect  None

Recovery  Informational message only; no corrective action required.

Cause  Generated whenever a Subnet Database is activated by the MEU, or as part of an event delete or insert sequence to record a modification of the Local System Information Table (LSIT) entry.

Effect  The Local System Information Table entry is inserted or modified.

Recovery  Informational message only; no corrective action required.

Cause  Generated as part of an event delete or insert sequence to record a modification of the Local System Information Table (LSIT) entry.

Effect  The Local System Information Table entry is modified.

Recovery  Informational message only; no corrective action required.

Cause  Generated whenever a new entry is added to an end point database table, or as part of an event delete or insert sequence to record a modification of an existing end point table entry.

Effect  The end point database table entry is inserted or modified.

Recovery  Informational message only; no corrective action required.

Cause  Generated whenever an end point database table entry is deleted, or as part of an event delete or insert sequence to record a modification of an existing end point table entry.

Effect  The end point database table entry is deleted or modified.

Recovery  Informational message only; no corrective action required.

Cause  Generated whenever a new remote system is added to the local Subnet Database, or as part of an event delete or insert sequence to record a modification of an existing remote system entry.

Effect  The corresponding remote system entry in the local Subnet Database is added or modified.

Recovery  Informational message only; no corrective action required.

Cause  Generated whenever a remote system is deleted from the local Subnet Database, or as part of an event delete or insert sequence to record a modification of an existing remote system entry.

Effect  The corresponding remote system entry in the local Subnet Database is deleted or modified.

Recovery  Informational message only; no corrective action required.

Cause  The MEU starts components during its initialization. The MEU resets components whenever the Subnet Database is changed.

Effect  The affected MEU component is stopped, started, or reset. A NonStop CPU which is power-cycled or reset while these services are unavailable will not boot properly.

Recovery  Informational message only; no corrective action required.

Cause  The MEU received an informational event from a NonStop CPU.

Effect  None

Recovery  Informational message only; no corrective action required.

Cause  Generated whenever an MEU establishes, or loses, connectivity with a NonStop CPU.

Effect  MEU connectivity with the NonStop CPU is either established (opened) or lost (closed).

Recovery  Transient connectivity loss is expected during NonStop CPU State changes (for example, when a CPU Halts, or when it is Reloaded). However, if the connectivity loss persists, ensure the affected NonStop CPU is properly configured within each MEU’s Subnet Database. Contact HP support if connectivity loss appears permanent.

Cause  A Maintenance Entity Unit message could not be translated to an MEU event.

Effect  This generic MEU event is logged instead.

Recovery  Ensure you are running the latest T0939 SPR, as older SPRs may not recognize all the messages generated by newer Maintenance Entity Units.

Cause  Generated whenever an MEU services a client request for a sensitive command.

Effect  None

Recovery  Informational message only; no corrective action required.

Cause  An MEIOLib client (for example, OSM SST) opened a session with the MEU.

Effect  None

Recovery  Informational message only; no corrective action required.

Cause  An MEIOLib client (for example, OSM SST) closed a session with the MEU.

Effect  None

Recovery  Informational message only; no corrective action required.

Cause  The MEU purged a stale entry from its session table.

Effect  None

Recovery  Informational message only; no corrective action required.

Cause  The MEU generated an Internal Trace event.

Effect  None

Recovery  Informational message only; no corrective action required.

Cause  The MEU generated an ME Info event which could not be fully translated.

Effect  This generic MEU event is logged instead.

Recovery  Ensure you are running the latest T0939 SPR, as older SPRs may not recognize all the messages generated by newer Maintenance Entity Units.
