Partition
A partition
is a group of managed devices formed by
IP Availability Manager
to
help in root-cause analysis. IP Availability Manager
builds a topology that describes managed
devices in your network and their interconnections. If a device is
modeled in the topology, there must be a path in the actual network
that connects the device to the management station. Ideally, IP Availability Manager
can
also have representations of all the devices on that path.However,
some devices along the path might not actually be represented in your
network topology. For example, those devices might not have SNMPAgents,
or
IP Availability Manager
might not have access to their SNMPAgents, or access to the agents
might be blocked by a firewall or some other administrative mechanism.
Also, if you do not use autodiscovery, your seed file or information
obtained from another Network Management System (NMS) might be incomplete.
Or, you might have explicitly unmanaged or deleted some of the devices
which are on that path.IP Availability Manager
's root-cause analysis algorithms need
to determine the connectivity among managed devices. When the topology
is incomplete, IP Availability Manager
creates partitions to group all the related managed devices,
which helps analysis to proceed.Within a single partition,
any two managed devices are indeed connected by a path. However, objects
within distinct partitions have no path between them in the modeled
topology, even though they are connected in the actual network.
Because many configurations produce large numbers of apparently isolated
objects, usually hosts,
IP Availability Manager
only creates partitions with two or more
devices.You can assign names to the partitions in your network
using the partition.conf file. The provides more information about naming partitions.
