System Management Interface Based on HPI-B (Centellis CO31kX/4100/2000/4410) User’s Guide 35
If you want to access the HPI daemon via the virtual IP address, then you need to specify the
respective IP address in your configuration file. In a Centellis 4100 context for example, an entry
might look like this:
[ShelfFrodo]
Daemon=192.168.20.171
Port=4743
Once the previously described switching mechanism exists, your application can access the
virtual IP address and open a connection. Since the virtual IP address is used, the application
would automatically be connected with the active HPI daemon. If the application detects that
the connection to the HPI daemon gets lost, it would reconnect to the same virtual IP address
Centellis 2000 172.16.<shelfID>.171
Access is possible either via the backplane or
via the ATCA-MF105 face plate connector
UPLINK ETH, which provides an uplink to the
system’s base interface.

Virtual IP of Active ATCA-
M100/MF105/SAM1410
It is important to note that the HPI-B library does not automatically switch between the two
interfaces towards the two switch blades when a switchover or failover between the two
switches occurs.
This becomes a problem in situations when one switch blade fails and the connection to the
currently active ATCA-M100/MF105/SAM1410 is interrupted. In such situations it becomes
necessary that an underlying mechanism, such as for example a bonding driver, switches to
the second interface and so that the active ATCA-M100/MF105/SAM1410 can be accessed
via the second interface.
Before accessing the HPI daemon via the virtual IP address, you must make sure that such a
switching mechanism exists. Refer also to the respective system guides for information
about the system network topologies.
