To enable event settings, you must set the associated attribute to a nonzero value between one
and thirty one. The exact value you specify determines which event notification method Fabric
Watch uses if the event setting criteria is met.
For details about valid notification methods in the alarm matrix, see ”Assigning notification
methods” on page 41.
Switch event (error) log entry
The switch event (error) log holds up to 1024 entries. This error log stores event information
but does not actively send alerts. Use the ErrShow command to view the log.
Log entries can also trigger SNMP traps if the SNMP agent is configured. When the SNMP
agent is configured to a specific error message level, then error messages at that level triggers
SNMP traps. For information on configuring the SNMP agent using the agtCfgSet
command, see the HP StorageWorks
Fabric OS 4.x command reference guide
.
SNMP trap
The Simple Network Management Protocol (SNMP) performs an operation called a
trap
that
notifies a management station (a workstation that runs network management applications
using SNMP protocol) when events occur.
You must configure the software to receive trap information from the network device. You must
also configure the SNMP agent on the switch to send the trap to the management station using
the agtCfgSet command. For more information on this command, refer to the
HP
StorageWorks
Fabric OS 4.x command reference guide.
An SNMP trap forwards the following information to an SNMP management station:
Name of the element whose counter registered an event
Class, area, and index number of the threshold that the counter crossed
Event type
Value of the counter that exceeded the threshold
State of the element that triggered the alarm
Source of the trap
The trap stores event information but does not actively send alerts. Port changes do not
generate SNMP traps.
RAPITrap
RAPITrap is a Fabric Watch alarm that actively alerts you to events. After you enable
RAPITrap, Fabric Watch forwards all event information to a designated proxy switch. The host
API automatically configures the proxy switch, based on firmware version. The switch
forwards the information to a server and alerts the SAN manager to event activity.
