Suppressing Problem Attributes
To suppress a problem attribute, select the attribute (in either the Attributes tab or the Attributes
dialog box), right-click, and select Suppress (see Figure 10), the either Temporary or Permanent
suppression. Select temporary to suppress as long the specific value of the attribute (Hard Down,
in this example) remains the same. If you bring the tape drive up and then it returns to the Hard
Down state, that value is no longer suppressed. Permanent suppression continues to suppress a
value of Hard Down for this tape drive until you unsuppress it. OSM Rediscover actions have no
effect on suppressed attributes.
With OSM version T0682 H02 ABX and later, suppression of attributes is persistent by default.
That means attributes suppressed in the OSM Service Connection remain suppressed even after
the OSM server has been stopped and restarted, unless the conditions for ending Temporary
suppression have been met. To disable suppression persistence with OSM T0682 H02 ABX and
later, see “Disabling Alarm and Attribute Suppression Persistence” (page 21) for the necessary
OSMCONF parameter.
Persistence is not available in OSM versions prior to T0682 H02 ABX, meaning that all suppressed
values revert to unsuppressed when the current OSM server session is ended.
