When a device resource item is removed, such as a disk, a self monitoring alarm is generated, and the device is supposed to be but is not being added to the detached section. 

The Detached folder must be enabled via a raw configure key. 

Release : 8.51

Component : UIM- HP_3PAR

The Detached folder only works for static profiles and does not work when templates are used. 

To enable the Detached folder go to hp_3par raw configure > setup > add key:
name: show_detached_configuration 
value: true
Apply > OK > deactivate > activate

When templates are used the number of alarms generated can be reduced via these raw configure keys:
raw configure > setup > add key:
enable_self_monitoring_alarm = false
enable_self_monitoring_alarm_aggregation = false
enable_self_monitoring_alarm_same_error_suppression = true
Apply > OK > deactivate > activate
