System Monitoring Plug-in Installation Guide for EMC Celerra Server
10g Release 2 (10.2.0.2)
This document provides a brief description about the Oracle System Monitoring Plug-in for EMC Celerra Server, details on the versions the plug-in supports, prerequisites for installing the plug-in, and step-by-step instructions on how to download, install, verify, and validate the plug-in.
The System Monitoring Plug-in for EMC Celerra Server extends Oracle Enterprise Manager Grid Control to add support for managing EMC Celerra Network Attached Storage (NAS) servers. By deploying the plug-in in your Grid Control environment, you gain the following management features:
Monitor EMC Celerra NAS servers.
Gather configuration and track configuration changes for NAS servers.
Raise alerts and violations based on thresholds set on monitoring and configuration data.
Provide rich out-of-box reports for the user interface based on the gathered data.
Support monitoring by a remote Agent. For remote monitoring, the Agent does not need to be on the same computer as the Celerra Server.
This plug-in supports the following versions of products:
Enterprise Manager Grid Control 10g Release 2 or higher Management Service
EMC Celerra servers with Clariion (NS 600/700 and NS 700G), and future versions of EMC Celerra servers provided that they are backward-compatible
Enterprise Manager Grid Control 10g Release 2 or higher Agent on any UNIX platform (such as Linux, HP UX, and Solaris)
EMC Celerra Software/CLI version 5.3
The following prerequisites must be installed before you can deploy version 184.108.40.206.0 of the plug-in:
Oracle Enterprise Manager Grid Control 10g Release 2 or higher system and Agent.
The EMC Celerra Plug-in can only be deployed on UNIX Agents, not Windows.
Secure Shell (SSH) must be configured to bypass the Control Station host user password. See "Configuring SSH to Bypass the Password" for the procedure.
SSH should be installed in:
This version of the plug in with SNMP support requires the following:
Oracle Management Services (OMS) version 10.2.0.1
One-off patch for Enterprise Manager version 10.2.0.1 based on Oracle bug #5349647
Version 10.2.0.2 of the Agent
After you ensure that the prerequisites are met, follow these steps to deploy the plug-in:

The following sections provide the configuration steps to be performed on the EMC Celerra control station to send SNMP traps to the Enterprise Manager EMC Celerra Plug-in. For more information about the EMC Celerra event and notification system, refer to the following EMC-provided documentation:
Celerra Network Server Technical Module — Configuring Celerra Events and Notifications
The SNMP Trap Configuration file specifies the SNMP Manager to which the trap should be sent. To receive SNMP traps from the Celerra Control Station, you can modify the default trap configuration file /nas/site/trap.cfg or create a new configuration file. A different file is required if more than one SNMP manager is listening for different SNMP traps. The SNMP Trap Configuration file is referenced in the Notification Configuration file, which is described in the next section.
If you plan to use the default Notification Configuration file specific to Enterprise manager as described in the next section, you should create a new SNMP Trap Configuration file (em_trap.cfg) by performing the following steps.
Ensure that the prerequisites for SNMP are met. See "Prerequisites".
Log in to the EMC Celerra control station as a NASADMIN user.
cp trap.cfg em_trap.cfg
Modify the contents of em_trap.cfg by uncommenting and changing snmpmanager to point to the emagenthost:emagentport format, as shown in the following example:
snmpmanager 22.214.171.124:5125 ; communityname public
The Notification Configuration file specifies the list of events for which notifications are to be sent. The default notification file,/nas/sys/nas_eventlog.cfg, contains all the default notification events with different types of notification methods (call home, SNMP trap, email, log, exec, and so forth).
You can either modify the default notification file,/nas/sys/nas_ eventlog.cfg, or create a new one specific to Enterprise Manager with a subset of events. The following procedure provides a sample Notification Configuration File, em_snmp_eventlog.cfg, which contains power status, fan status, reboot events, and failover events. You can add more events as required. Refer to the EMC-provided documentation, Celerra Network Server Technical Module — Configuring Celerra Events and Notifications, for details on the format of the Notification Configuration file.
Perform the following steps to create and load the file:
Log in to the EMC Celerra control station as a NASADMIN user.
Create the em_snmp_eventlog.cfg file with the following contents:
# # Notification file for Enterprise Manager plug-in for EMC Celerra # # BoxMonitor # Fan status, power status events for CNS-14, Reboot events for ALL platforms facilitypolicy 131, 4 disposition range=1-1, trap "/nas/site/em_trap.cfg 2" disposition range=3-15, trap "/nas/site/em_trap.cfg 2" disposition range=18-21, trap "/nas/site/em_trap.cfg 2" disposition range=38-39, trap "/nas/site/em_trap.cfg 2" disposition range=43-43, trap "/nas/site/em_trap.cfg 2" disposition range=57-58, trap "/nas/site/em_trap.cfg 2" disposition range=62-67, trap "/nas/site/em_trap.cfg 2" disposition range=70-70, trap "/nas/site/em_trap.cfg 2" disposition range=73-73, trap "/nas/site/em_trap.cfg 2" disposition range=100-115, trap "/nas/site/em_trap.cfg 2" disposition range=200-215, trap "/nas/site/em_trap.cfg 2" disposition range=300-315, trap "/nas/site/em_trap.cfg 2" # # Enclosure Monitor # Fan status, power status events for NS platform facilitypolicy 86, 7 disposition severity=0-3, trap "/nas/site/em_trap.cfg 2" disposition severity=4-4, trap "/nas/site/em_trap.cfg 3"
Edit the file to add any other events if needed.
Enter the nas_event command as shown in the following example:
[nasadmin@erpcel01-con site]$ nas_event -Load /nas/site/em_event_config.cfg EventLog : will load /nas/site/em_snmp_eventlog.cfg... done
Verify if the file is loaded by entering the nas_event command as shown in the following example:
[nasadmin@erpcel01-con site]$ nas_event -Load -info
Loaded config. files:
To map EMC severities (0-7) to Enterprise Manager severities, use the following required Oracle SNMP Enterprise-specific traps:
SNMP trap 2 to send critical alerts (EMC-defined severity <= 3)
SNMP trap 3 to send warning alerts (EMC-defined severity <= 4)
After you deploy the plug-in and set up a target as instructed in the System Monitoring Plug-in Installation Guide for EMC Celerra Server, you can use the nas_snmptrap command to send SNMP trap tests.
Log in to the EMC Celerra control station as a NASADMIN user.
Run the nas_snmptrap command.
The syntax of the command is as follows:
/nas/sbin/nas_snmptrap <config_file_path> -m /nas/sys/emccelerra.mib -r <trap_number> -f <facility_id> -i <event_id> -s <severity_level> -d "<description>"
<config_file_path> = the path of the trap configuration file /nas/sys/emccelerra.mib = the Celerra MIB file <trap_number> = the unique trap number for the event <facility_id> = the ID number of the facility generating the event <event_id> = the event ID number <event_id> = the event ID number <description> = the description of the trap
The following example shows how to send a critical alert:
/nas/sbin/nas_snmptrap /nas/site/em_trap.cfg -m /nas/sys/emccelerra.mib -r 2 -f 64 -i 2 -s 2 -d "Test SNMP trap Critical Alert"
The following example shows how to send a warning alert:
/nas/sbin/nas_snmptrap /nas/site/em_trap.cfg -m /nas/sys/emccelerra.mib -r 3 -f 65 -i 3 -s 3 -d "Test SNMP trap Warning Alert"
Verify the alerts as follows:
Log in to Grid Control.
Go to the EMC Celerra Target. Under the Reports Tab, view the EMC Celerra SNMP Trap-based Alerts Report. This should list the alert corresponding to the trap test that is sent.
Go to the Grid Control Console Home Page. Under All Targets Alerts, Click the Critical or Warning link. Filter the targets by EMC Celerra Server type. You should see the alert corresponding to the trap test that is sent. You can then select and clear the alert.
Follow these steps to undeploy the plug-in from an Agent:
Log in to Enterprise Manager Grid Control as a Super Administrator.
Select the Targets tab, then the All Targets subtab. The All Targets page appears.
Select the EMC Celerra Server Plug-in target and click Remove. You must do this step for all targets of the plug-in.
Make sure that the preferred credentials are set on the Agents where the plug-in was deployed.
Click the Setup link in the upper right corner of the All Targets page, then click the Management Plug-ins link on the left side of the Setup page. The Management Plug-ins page appears.
Click the icon in the Undeploy column for the EMC Celerra Server Plug-in. The Undeploy Management Plug-in page appears.
Check all the Agents that are currently deployed with the EMC Celerra Server Plug-in and click OK.
You must undeploy the plug-in from every Agent in the system to completely remove it from the enterprise.
Select the EMC Celerra Server Plug-in on the Management Plug-ins page and click Delete.
