2.3.2.2 Accessing the HPI Daemons via Virtual IP Addresses
In Centellis 2000 R3.0/4411 systems, you can access the ATCA-MF106/SAM1411 blades via
virtual IP addresses. One virtual IP address is automatically linked to the currently active ATCA-
MF106/SAM1411 blade. The following table shows which IP address this is for the different
systems.
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 4411 context for example, an
entry might look like this:
[ShelfFrodo]
Daemon=192.168.20.171
Port=4743
Table 2-8 Virtual IP Addresses Corresponding to Active ATCA-MF106/SAM1411 Blade
System Virtual IP of Active ATCA-MF106/SAM1411
Centellis 2000 R3.0 172.16.<shelfID>.171
Access is possible either via the backplane or
via the ATCA-MF106 face plate connector
UPLINK ETH, which provides an uplink to the
system’s base interface.
Centellis 4411 192.168.20.171
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-MF106/SAM1411 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-MF106/SAM1411 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.
