IBM Tivoli Storage Manager, Version 7.1

Configuring IBM Tivoli Storage Manager SNMP

You can configure SNMP by completing the following procedure.

About this task

The IBM® Tivoli® Storage Manager SNMP set up procedure is illustrated by Figure 1:

Figure 1. IBM Tivoli Storage Manager SNMP Set Up

To set up Tivoli Storage Manager monitoring through SNMP, do the following:

Procedure

Modify the server options file to specify the SNMP communication method. Figure 2 displays an example of a SNMP communication method setting in the server options file.
You must specify the COMMMETHOD and SNMPSUBAGENT options. The SNMPSUBAGENT option must specify a host that is an AIX® system with a DPI-enabled SNMP agent, such as the SystemView® agent.
Figure 2. Example of SNMP communication method options
```
 commmethod                 snmp
   snmpsubagent             hostname jimbo communityname public timeout 600
   snmpsubagentport         1521
   snmpheartbeatinterval    5
   snmpmessagecategory      severity         
```
For details about server options, see the server options section in Administrator's Reference.
Install, configure, and start the SNMP agent as described in the documentation for that agent. The SNMP agent must support the DPI Version 2.0 standard. Tivoli Storage Manager supports the SNMP agent that is built into the AIX operating system.
Configure the AIX SNMP agent by customizing the SNMP file; the SNMP, V1 file is named: /etc/snmpd.conf, the SNMP, V3 file is named: /etc/snmpdv3.conf. A default configuration for SNMP, V1 might look like this:
```
logging    file=/var/snmp/snmpd.log  enabled                      
logging    size=0  level=0                                        
community  public                                                
community  private 127.0.0.1   255.255.255.255 readWrite         
community  system  127.0.0.1   255.255.255.255 readWrite  1.17.2 
view       1.17.2 system enterprises view                         
trap       public  <snmp_manager_ip_adr>   1.2.3 fe             
snmpd      maxpacket=16000 smuxtimeout=60                         
smux       1.3.6.1.4.1.2.3.1.2.2.1.1.2 public
```
where is the IP address of the system running the SNMP management application.
Attention: The trap statement also defines the system to which the AIX SNMP agent forwards traps that it receives.

Before starting the agent, ensure that the dpid2 and snmpd subsystems have been started.
Important: The dpid2 subsystem is started automatically through the snmpd subsystem in SNMP, V3. The dpid2 subsystem must be manually started independently of the snmpd subsystem with SNMP, V1.
The snmpd and dpid2 subsystem status can be reviewed by issuing the following commands:
```
lssrc -s snmpd 
lssrc -s dpid2 
```
The subsystems can be started by issuing the following commands:
```
startsrc -s dpid2 
startsrc -s snmpd
```
Start the Tivoli Storage Manager SNMP subagent by running the dsmsnmp executable.
Start the Tivoli Storage Manager server to begin communication through the configured TCP/IP port with the subagent.
Begin event logging for the SNMP receiver, and enable events to be reported to SNMP. For example, issue the following commands:
```
begin eventlogging snmp  
enable event snmp all                                      
```
Define the Tivoli Storage Manager SNMP MIB values for the SNMP manager to help format and display the Tivoli Storage Manager SNMP MIB variables and messages. The adsmserv.mib file ships with the Tivoli Storage Manager server and must be loaded by the SNMP manager. This file is in the installation directory of the server. For example, when you run NetView® for Windows as an SNMP manager, the adsmserv.mib file is copied to the \netview_path\SNMP_MIB directory and then loaded through the following command:
```
[C:\] loadmib -load adsmserv.mib 
```
