Default Threshold Values
Factory-configured default threshold values are provided in the N1 System Manager software for some OS health thresholds. These values are stated as percentages. Table 6–3 lists default values for these OS health attributes.
Note –
Setting or modifying threshold values for hardware health attributes is not supported in this version of the Sun N1 System Manager.
