Limitations for CWM to CWM Communications
The Secondary CWMs have to wait for the Primary CWM to finish syncing up with the network.
Trap 28075 (svDatabaseInSync) is sent when the Primary CWM has finished syncing up with the
network.
All the CWM workstations managing the sam e netwo rk must ha ve seed nodes or gate way no des that
have IP addresses within the same domain.
Note The network.conf file does not have to be the same on all CWM stations in the domain as long
as the gateway nodes specif i ed in thi s f i le a re part of t he s ame ne tw or k. Ev en t ho ugh CWMs t hat
manage the same network can talk to each other, managing the same network does not require
having identical network.conf files on all Secondary and Primary CWMs.
The Configurator can on ly be run on the Prim a ry CWM.
If all the Secondary CWM Gateways lose IP connection with the Primary CWM Gateway (no
heartbeat received in the past 2 con secu tive Heartbeat Intervals), then all th e Secondary CWM
Gateways will function in degraded mode and wait for the connection problem to be resolved.
Note Do not cold start -F without first verifying that a Secondary CWM has s witched over to become
the new Primary CWM of the domain, otherwise the node_id and other user data will become
inconsistent.
