Description: ATTENTION: Setting this objects value to start(5) will initiate an Alarm List
Rebuild process. During this process ALL ALARM INFORMATION WILL BE DELETED !
The Alarm List Rebuild process
==============================
When an employee discovers that the internal alarm table of the A.I.M.O.S. SNMP
Agent is flawed, an alarm list rebuild can be triggered. Such a process may also
be necessary if productive operation is to start after a test phase with an empty
alarm list.
The Alarm List Rebuild consists of the following steps:
. A SNMP Manager sets aimosAlarmListRebuild to start(5). The logged in user
must belong the Provider.
. The A.I.M.O.S. SNMP Agent drops the contents of the internal alarm tables. The
table is completely deleted; each alarm list entry for each organisation is
removed !
. The A.I.M.O.S. SNMP Agent resets each alarm notification related counter to
zero. These counters are aimosAlarmListID, aimosAlarmListAlarmEventID,
aimosAlarmTrapID and each managers aimosAlarmTrapNotificationID. The values of
these counters are increased by one with each new alarm, i.e. with the first
alarms the value is 1. A counter of 0 is only possible after the maximum value
(2^32-1) has been reached; which is, however, highly unlikely.
. The aimosAlarmListRebuildInitiated notification is forwarded to all SNMP
Managers configured to receive this alarm. This will result in
. one new alarm list entry per affected organisation
(with aimosAlarmListID and aimosAlarmListAlarmEventID each set to 1) and
. one trap list entry per affected manager
(with aimosAlarmTrapNotificationID set to 1 and per SNMP Manager consecutive
numbered values beginning with 1 in aimosAlarmTrapID)
. The A.I.M.O.S. devices are informed about the rebuild in order to reset its
internal alarm tables, too. The devices will report still existing alarms as new
alarms immediately.
. Suppress forwarding of further notifications to a specific manager until the
manager acknowledges the aimosAlarmListRebuildInitiated notification. If the
acknowledgement is missing for a specific period of time, the agent obviously
emits the aimosAlarmListRebuildInitiated notification again
On receipt of the aimosAlarmListRebuildInitiated notification, the SNMP Manager
shall clean the internal alarm table prior to acknowledge this notification.
There is no aimosAlarmCleared notification for this alarm. The alarm gets cleared
on acknowledgement. Alarm notifications received after that acknowledgement needs
to get acknowledged by the manager as usual; the manager is neither required nor
able to distinguish if a notification is a result of the alarm list rebuild or a
new (never received before) one.
Changes, which are made here, affect all organizations.
That's why TelCo's are not allowed to initiate an Alarm List Rebuild Process
by setting this value to start(5).What is aimosAlarmListRebuild?
Set to 'start(5)' to trigger full alarm rebuild (erases all alarm data). Emergency recovery operation. Example: Set to 'start(5)' after suspected data corruption.
