What Features Are Unavailable While in Fault Tolerance in DX NetOps Spectrum ?


Article ID: 211302

DX NetOps


We are working to determine the options for a full Disaster Recovery  DX NetOps Spectrum configuration. 

To start, we want to identify :

a) What features are NOT available when in switched mode? 

b) We need some outlines of the limitations of Fault Tolerance (aside from SRM and AlarmNotifier) for when a primary server goes down and OneClick switches to the secondary.


DX NetOps Spectrum 23.x.x


Following are the features that will NOT Work

User/Group Creation    

Create a Schedule

Autodiscovery will not work if the MLS or "home landscape" is down.  You will see errors SPC-OCC-10895 and SPC-OCC-10896

Global Collection Creation as you will receive a Create Error - The model <name> could not be created in some landscapes.  The secondary landscape is currently active.

- All the IP service (MPLS/Vpn/Evpn/QoS) discoveries are restricted and will not run on secondary.

- Most of the Integrations(UIM/VNA/NetOps Portal) are restricted and will not do any inventory discovery.

Additional Information

Note - The following features WILL WORK

a) ArchMgr
b) AlarmNotifier (typically requires script modification so only the active landscape fires)
c) Single Device Discoveries in the Topology
d) Auto Discoveries as long as the MLS or home landscape is not down.
e) Network Configuration Manager

* Models, Host Configs ... will be lost when the primary comes back online unless the SSdb from the FT is saved and reloaded on the primary server
