Connectivity unit event table
connUnitEventTable
OID 1.3.6.1.3.94.1.11
Description The table of connectivity unit events. Errors, warnings, and information should be
reported in this table.
connUnitEventEntry
OID 1.3.6.1.3.94.1.11.1
Description Each entry contains information on a specific event for the given connectivity unit.
connUnitEventUnitId
OID 1.3.6.1.3.94.1.11.1.1
Description The connUnitId of the connectivity unit that contains events in this event table.
Note This displays the WWN value of the local switch for all the events.
connUnitEventIndex
OID 1.3.6.1.3.94.1.11.1.2
Description Each connectivity unit has its own event buffer. As it wraps, it may write over previous
events. This object is an index into the buffer. HP recommends that this table be read
using getNext commands to retrieve the initial table.
The management application should read the event table at periodic intervals and then
determine whether any new entries were added by comparing the last known index
value with the current highest index value. The management application should then
update its copy of the event table. If the read interval is too long, it is possible that there
may be events that may not be contained in the agent's internal event buffer.
For example, an agent may read events 50-75. At the next read interval,
connUnitEventCurrID is 189. If the management application tries to read event index 76,
and the agent's internal buffer is 100 entries maximum, event index 76 is no longer
available.
The index value is an incrementing integer starting from one every time there is a table
reset. On table reset, all contents are emptied and all indices are set to zero. When an
event is added to the table, the event is assigned the next higher integer value than the
last item entered into the table. If the index value reaches its maximum value, the next
item entered causes the index value to roll over and start at 1 again
connUnitEventId
OID 1.3.6.1.3.94.1.11.1.3
Description The internal event ID. Incremented for each event, ranging between 0 and
connUnitMaxEvents. Not used as table index to simplify the agent implementation. When
this reaches the end of the range specified by connUnitMaxEvents, the Id rolls over to
start at zero. This value is set back to zero at reset. The relationship of this value to the
index is that internal event id may represent a smaller number than a 32-bit integer (for
example, max 100 entries) and would only have a value range up to
connUnitMaxEvents.
