Detecting Issues - Hitachi 3080 Network Administration Manual

Detecting issues

The HNAS server contains an automatic diagnosis system which identifies,
categorizes and prioritizes problems and then presents the information to the
user through the console.
To activate the diagnosis system, use the trouble command.
This command contains 'groups' which refer to parts of the server and its
storage, for example, there is a Network group and a Storage group. Trouble
also contains 'reporters'. These are individual programs which investigate
issues within the groups.
For example, the Network group contains the following reporters:
CLUSTER-2:$ trouble --list-reporters network

network aggregation
network network-statistics 180 MMB Network interface statistics
network nim-vlsi
network network-interfaces 200 MMBNetwork interfaces link status

network wins
network ip-eng-adv
network mac-cluster
network mac-network
network external-migration-protocol-errors 350 MMB External

network packet-capture
not running
network remote-http
There are two types of reporters:
• Fault reporters - these detect issues which can cause degradation of
service.
• Performance reporters - these detect performance values which are out-of-
range (unexpectedly high or low).
This command operates over all cluster nodes unless configured otherwise.
Example of common command usage
The following command reports all issues with the HNAS network group.
trouble network
The report appears as shown in the example below:
