HP SIM 7.4 Enclosure fail-over SAS Switch not detected

[Smithy1975]

Hello,
first of all: see attachment to understand the situation better.

This interesting phenomenon occured as soon as HP SIM was installed and discovered the enclosure system: 
3Gb SAS Switches.
1. SAS Switch: VSM (active)
2. SAS Switch: VSM (passive)

The passive one doesn't seem to be detected probably because it has no valid IP due to the fail-over configuration, but is there any way to make HP SIM monitor health status of this passive switch too?
Thank you for any help with this issue.
