206 VADSM - Administration of NMC alarms in the SM


Restrictions	Functions of the AMO	Error Messages and Advisories
Interrelationships	Parameter Description

The AMO VADSM is used to administer the validation data of the NMC alarms (NMC = Network Management Center) for the dependability system in the SM.

At a higher level, these alarms are used to indicate global system faults.

At the AMO level, NMC alarms are handled in much the same way as error messages, i.e. they are output to the standard output devices such as printer, PC, RMA (Hicom teleservice or NMC).

Validation data for an alarm:

a)

THRESHOLD VALUE for major (urgent) and minor (non-urgent) alarms

To indicate the respective alarm level the error counter assigned to the alarm must have reached or exceeded the threshold value within the specified validation time. Both major and minor alarms can also be deactivated.

b)

VALIDATION TIME for major and minor alarms

The validation time, which must be specified for each alarm level (major/minor), ensures that ’sporadic’ faults are not indicated immediately. Much rather they are indicated upon expiry of the validation time, i.e. a specified time during which the error was continuously present. Only then will the alarm be indicated. Alternatively, the alarm will only be deactivated if the respective threshold value is not reached during the validation time.

c)

VALIDATION TIME for single device alarm

Failed units or devices below the threshold levels specified for the minor or major alarms are indicated by the single device alarm. The single device alarm is indicated when at least one unit is continously defect during the validation time for single device alarm. The single device alarm is deactivated when its validation time is set to 0.

d)

A global filter for alarm messages has been added to the system to prevent not-service-relevant messages. AMO-SIGNL defines the minimum priority of the alarms which are forwarded by SIT. The priority of each single alarm can be changed by AMO-VADSM.

e)

Alarms can also be signalized by LEDs. The parameter ’HWCONT’ defines, which LEDs are assigned to which alarm(s). Normally HWCONT = SU for all alarms. This means : When at least one minor alarm is active, the LEDs ’P2’ on IOP and ’NAL’ on DP are in state ’on’ and when at least one major alarm is active, the LEDs ’C3’ on IOP and ’UAL’ on DP are in state ’on’ (summary signalisation). When HWCONT is set to S1 for one (or more) alarm(s), ’P2’ and ’NAL’ are on only when this (or these) alarm(s) are active. In the same way : When HWCONT is set to S2 for one (or more) alarm(s), the LEDs ’C3’ and ’UAL’ are on only when this (or these) alarm(s) are active.

Central SM alarms

Central SM alarms are used to indicate faults in common or shared HW components in the system.

Central alarms are preset by the system. There are central alarms for the SWU, the ISp (ADS) and the ISs (server). The AMO VADSM can only be used to change threshold values and validation times.

Out of 64 possible central alarms, the table below refers only to those central alarms which are used in the SM:

Peripheral SM alarms

Peripheral SM alarms (up to 24) are used to indicate faults in the SM periphery. The SM periphery includes the TTY / VM / FAX hardware configured in the ISp and ISs as well as the storage periphery (HD / cartridge).

Peripheral SM alarms are preset by the system. The AMO VADSM can only be used to change threshold values and validation times.
