Verify SNMP Communications With the Library

Use this procedure to verify that the STA server is able to communicate with the library using the SNMP protocol. This procedure verifies that UDP ports 161 and 162 have been enabled on all network nodes between the STA server and the library.

1.
Establish a terminal session with the STA server, and log in as root.

See your STA server administrator for login information.

2.
To ensure SNMP services are turned off (deconfigured) and stopped, perform the following:
a.
Deconfigure SNMP services:
 
# chkconfig snmpd off
# chkconfig snmptrapd off
b.
Stop SNMP services:
 
# service snmptrapd stop
# service snmpd stop

Note – If you receive a “FAILED” error when executing the “service stop” commands, these SNMP services may already be stopped.

c.
Stop and restart STA services:
 
# STA stop
# STA start
3.
At the Linux command prompt, use the following command to test the SNMP connection by querying the library SNMP agent on the library. 
snmpget -v3 -u SNMP_user -a SHA -A auth_password-x DES ‑X priv_password -l authPriv library_IP_addr 1.3.6.1.4.1.1211.1.15.3.1.0

Note – To ensure the snmpget utility is available, see the “Ensure Availability of net-snmp-utils” section within the StorageTek Tape Analytics Planning and Installation Guide.

Where:

•
SNMP_user is the SNMP user you created in “Create an SNMP v3 User”.
•
SHA indicates the authentication protocol.
•
auth_password is the authorization password you assigned in “Create an SNMP v3 User”.
•
DES indicates the privacy protocol.
•
priv_password is the privacy password you assigned in “Create an SNMP v3 User”.
•
authPriv indicates that authentication with privacy is performed on the command.
•
library_IP_addr is the IP address of the public port on the library, as follows:
•
For SL500 libraries, this is always the 1B port; see “Retrieve the Library IP Address”.
•
For SL3000 and SL8500 libraries, there may be multiple ports you want to test, depending on whether the Dual TCP/IP and/or Redundant Electronics features are activated on the library. See “Retrieve SL3000 or SL8500 IP Addresses” for details. If there are multiple ports, you need to run this command once for each IP address.
•
1.3.6.1.4.1.1211.1.15.3.1.0 is the SNMP object identifier (OID) for the library; this entry is the same for all library models.
Example of a Successful Command

If the command displays the library model (for example, SL8500), this confirms the v3 user information and that all routes in the network between the library and the server on which STA is installed have ports 161 and 162 open.

Example of Unsuccessful Commands

4.
If the command was successful, proceed to “Log In to the STA User Interface”. If the command was not successful, contact your network administrator or Oracle support representative. You can also view the troubleshooting information in “Troubleshoot an Unsuccessful SNMP Connection”. You may need to troubleshoot issues with packet routing between the library and the STA server.
