source
One of two selection types for filtering OSM status messages. These category types are
supported:
SNMP OSM encountered an SNMP protocol error.
SP Interface
The OSM client or server application encountered an error while
performing an OSM operation.
System The OSM operation failed due to a system error.
User
The user specified an incorrect value for the requested operation. Check the
specified value and retry the operation.
split-star topology
A network topology that uses up to two HP NonStop Cluster Switches for each external
fabric. External routing is implemented between the two starred halves of a ServerNet
cluster. (A starred half consists of up to eight nodes attached to one set of cluster
switches.) The starred segments are joined by four-lane links. The split-star topology
supports up to 16 nodes.
See also star topology , tri-star topology , and layered topology .
star topology
A network topology in which all nodes are connected to a central hub (HP NonStop
Cluster Switch). Each node has its own connection to the network, so a break in the
connection does not affect other nodes in the network. In a ServerNet cluster, a star
topology requires one cluster switch for each external fabric and can support up to eight
nodes.

status/console message
A message that keeps the user informed about the status of the requested action.
subnetwork
A physical network within an internet protocol (IP) network. Each IP network can be
divided into a number of subnetworks. Within a given network, each subnetwork is
treated as a separate network. Outside that network, the subnetworks appear as part of a
single network. The terms subnetwork and subnet are used interchangeably.
subnetwork address
An extension of the internet protocol (IP) addressing scheme that allows a site to use a
single IP address for multiple physical networks. A subnetwork address is created by
dividing the local part of an IP address into a subnetwork number (identifying a particular
subnetwork) and a host number (uniquely identifying the host system within the
subnetwork). The terms subnetwork and subnet are used interchangeably.
