# Using the SNMP Trap Manager

Note: You cannot use the SNMP Trap Manager in startable-CD mode or when using the ServeRAID Manager as a plug-in application.

Use the SNMP Trap Manager to notify other systems running an SNMP console (such as IBM® Director) of all SNMP traps that occur on this (that is, the local) system. The user of the system types system names in the SNMP traps list. Each system in the list is notified of all traps that occur on the local system.

After configuring the remote systems to receive the SNMP traps using the SNMP Trap Manager, you can run the ServeRAID Manager agent on this (local) system, instead of the ServeRAID Manager. The ServeRAID Manager agent uses less memory resources than the ServeRAID Manager. On the remote system, use an SNMP console to monitor the SNMP traps that you receive.

You can use the SNMP Trap Manager to do the following:

- Add a system to the SNMP traps list
- Delete a system from the SNMP traps list
- Modify system properties in the SNMP traps list
- Send a test trap to a system in the SNMP traps list
- Monitor traps sent by SNMP

The SNMP Trap Manager is enabled by default. To disable the SNMP Trap Manager, click Actions Disable SNMP Traps. If you disable the SNMP Trap Manager, the SNMP traps are generated, but not dispatched to remote systems.

## An example

You install SystemA in a lab with a ServeRAID subsystem. You run the ServeRAID Manager agent (that is, the ServeRAID Manager without the graphical user interface) on SystemA to send SNMP traps, but you want to monitor from your workstation and not from SystemA. You open the SystemA SNMP Trap Manager from the ServeRAID Manager and define your workstation in the SNMP traps list. When running the SNMP console (such as IBM Director) from your workstation, you are notified of all SNMP traps that occur on SystemA.

## The SNMP Trap Manager and traps

Traps generated by SNMP include the following:

- Progress information, such as rebuilds, synchronizations, compressions, decompressions, and migrations.
- Problems, such as defunct physical drives and PFA errors.
- Changes to the local configuration, such as adding or replacing a controller, or failover.

When an SNMP trap is generated on a system, the SNMP Trap Manager connects with each system in the SNMP traps list and relays the trap to these systems' SNMP consoles. The SNMP traps list updates its Last trap sent column.

## The SNMP Trap Manager interface

The SNMP Trap Manager consists of the following:

Toolbar
  Provides quick-path icons for common tasks.
SNMP traps destination list
  Displays the remote systems configured to receive SNMP traps.
SNMP trap viewer
  Displays status information for the SNMP traps destination list.

  In addition to displaying the traps in the trap viewer, the SNMP Trap Manager appends each trap to a logging file, RaidSNMP.log. If this file exceeds 200 KB, the Manager copies the file to RaidSNMP.old and creates a new RaidSNMP.log. If there is a RaidSNMP.old already, the Manager overwrites it.
