Configuring the IMT Bus Alarm Thresholds

This procedure is used to change the IMT bus alarm thresholds using the chg-th-alm command and these parameters.

:imtbusutllvl1 – The percentage for the IMT bus combined utilization level 1 threshold alarm (reported on the IMT system). The percentage for the IMT bus combined utilization level 1 threshold alarm, from 35 to 70 and is shown in the IMT Bus Combined Utilization Alarm Level 1 field of the rtrv-th-alm output. The system default value is 70. When this threshold is exceeded, UAM 0027 is generated.

:imtbusutllvl2 – The percentage for the IMT bus combined utilization level 2 threshold alarm (reported on the IMT system). The percentage for the IMT bus combined utilization level 2 threshold alarm, from 40 to 80 and is shown in the IMT Bus Combined Utilization Alarm Level 2 field of the rtrv-th-alm output. The system default value is 80. When this threshold is exceeded, UAM 0028 is generated.

After the chg-th-alm command is performed, the imtbusutllvl2 parameter value must be greater than the imtbusutllvl1 parameter value.

:imtcongestlvl1 – The percentage for the IMT bus congestion level 1 threshold alarm (reported on the HIPR2 card). The percentage for the IMT bus congestion level 1 threshold alarm, from 35 to 70 and is shown in the IMT Bus Congestion Alarm Level 1 field of the rtrv-th-alm output. The system default value is 70. When this threshold is exceeded, UAM 0030 is generated.

:imtcongestlvl2 – The percentage for the IMT bus congestion level 2 threshold alarm (reported on the HIPR2 card). The percentage for the IMT bus congestion level 2 threshold alarm, from 40 to 80 and is shown in the IMT Bus Congestion Alarm Level 2 field of the rtrv-th-alm output. The system default value is 80. When this threshold is exceeded, UAM 0031 is generated.

After the chg-th-alm command is performed, the imtcongestlvl2 parameter value must be greater than the imtcongestlvl1 parameter value.

For more information on these alarms, refer to Unsolicited Alarm and Information Messages Reference.

The chg-th-alm command contains other optional parameters. These parameters are not shown here because they are not necessary to configure the IMT bus alarm thresholds. These parameters are explained in more detail in Commands User's Guide.

1. Display the current IMT bus alarm thresholds in the database by entering thertrv-th-alm command. This is an example of the possible output.

   rlghncxa03w 09-07-28 09:12:36 GMT EAGLE5 41.1.0
   IMT Bus Combined Utilization Alarm Level 1: 70%
   IMT Bus Combined Utilization Alarm Level 2: 80%
   IMT Bus Congestion Alarm Level 1:           70%
   IMT Bus Congestion Alarm Level 2:           80%
   RTRV-TH-ALM: MASP A - COMPLTD.
   

   Note:

   The rtrv-th-alm command output contains other fields that are not used in this procedure. If you wish to see all the fields displayed by the rtrv-th-alm command, refer to the rtrv-th-alm command description in Commands User's Guide.
2. Configure the IMT bus alarm thresholds by entering the chg-th-alm command with at least one of the IMT bus alarm threshold parameters.
   If an IMT bus alarm threshold parameter is not specified with the chg-th-alm command, that parameter value will not be changed. The system default values for the IMT bus alarm threshold parameters are:

   • imtbusutllvl1 – 70
   • imtbusutllvl2 – 80
   • imtcongestlvl1 – 70
   • imtcongestlvl2 – 80.

   After the chg-th-alm command is performed, the imtbusutllvl2 parameter value must be greater than the imtbusutllvl1 parameter value, and the imtcongestlvl2 parameter value must be greater than the imtcongestlvl1 parameter value.

   For this example, enter this command.

   chg-th-alm:imtbusutllvl1=50:imtcongestlvl1=50:imtbusutllvl2=70:imtcongestlvl1=70

   When this command has successfully completed, this message should appear.

   rlghncxa03w 09-07-28 09:12:36 GMT EAGLE5 41.1.0
   CHG-TH-ALM: MASP A - COMPLTD
   

3. Verify the changes using the rtrv-th-alm command. This is an example of the possible output.

   rlghncxa03w 09-07-28 09:12:36 GMT EAGLE5 41.1.0
   IMT Bus Combined Utilization Alarm Level 1: 50%
   IMT Bus Combined Utilization Alarm Level 2: 60%
   IMT Bus Congestion Alarm Level 1:           50%
   IMT Bus Congestion Alarm Level 2:           60%
   RTRV-TH-ALM: MASP A - COMPLTD.
   

   Note:

   The rtrv-th-alm command output contains other fields that are not used in this procedure. If you wish to see all the fields displayed by the rtrv-th-alm command, refer to the rtrv-th-alm command description in Commands User's Guide.
4. Backup the new changes using the chg-db:action=backup:dest=fixed command.
   These messages should appear, the active Maintenance and Administration Subsystem Processor (MASP) appears first.

   BACKUP (FIXED) : MASP A - Backup starts on active MASP.
   BACKUP (FIXED) : MASP A - Backup on active MASP to fixed disk complete.
   BACKUP (FIXED) : MASP A - Backup starts on standby MASP.
   BACKUP (FIXED) : MASP A - Backup on standby MASP to fixed disk complete.
