Description

The System Monitoring Plug-in for EMC CLARiiON System extends Oracle Enterprise Manager Cloud Control to add support for monitoring EMC CLARiiON System. By deploying the plug-in in your Cloud Control environment, you can do the following:

Monitor EMC CLARiiON Systems.
Gather storage configuration and performance information of various storage components.
Raise alerts and violations based on thresholds set on monitoring and configuration data.
Generate rich out-of-box reports for the user interface based on the gathered data. For details of reports, see Reports.
Monitor using a remote Agent. For remote monitoring, the Agent does not need to be on the same computer as the EMC CLARiiON System.

Versions Supported

This plug-in supports the following versions of products:

Enterprise Manager Cloud Control 12c Release 1 Management Service
Enterprise Manager Cloud Control 12c Release 1 Agent on Linux and Solaris

Note:
The EMC CLARiiON System Plug-in can only be deployed on Linux, Solaris and AIX, not Microsoft Windows. Refer to WebIV Note 465472.1 for the latest certification status on different platforms.

Prerequisites

The following prerequisites must be met before you can deploy the plug-in:

Oracle Enterprise Manager Cloud Control 12c Release 1 system and Agent.
EMC NaviCLI 6.14 and 6.19
Oracle Management System (OMS) version 10.2.0.3 or higher with relevant patches
An operating system user is created, for example oracle
The operating system user, for example oracle, is added to the agent.config file located at /etc/Navisphere/agent.config. For example:
```
user oracle@hostname
```
The username you use to log in to the current host is added to the security file. For example, to add yourself to the security file on the current host, given the alternative username altusername, the password mypass and the scope 0 (global scope), type:
```
naviseccli -AddUserSecurity -password mypass -scope 0 -user altusername
```
Where -AddUserSecurity directs the CLI to add user security information to the security file on this host, -password specifies the password for the username altusername and the agent must be configured for the user altusername, and -scope specifies whether the user account on the storage system you want to log in to is local or global. If no altusername is provided, the user currently logged in will be added as a naviseccli user, and the password provided in the above command must be of that user.

Note:
To add a user to the security file, you must be logged in as oracle.
(For Enterprise Manager 10.2.0.3) Patch 5844887 is applied on Oracle Management Service to enable filtering of data in the reports.
(For Enterprise Manager 10.2.0.3) Patch 6113649 is applied on agent to enable the appearance of EMC CLARiiON Device.
(For Enterprise Manager 10.2.0.3) Agent Patch 6269838 is applied on hosts that have EMC power path configured. You will need to apply this patch to view EMC power path devices in the database, ASM, and host mapping reports.
To deploy and monitor EMC CLARiiON from Solaris 9/10, Patch 7005747 is applied to agent version 10.2.0.4.0 on Solaris 9 and 10. This patch enables the EMC CLARiiON plug-in to monitor all non-zero size slices of the Solaris host.

Deploying the Plug-in

See the Plug-in Manager chapter in the Oracle Enterprise Manager Cloud Control Administrator's Guide for steps to deploy the plug-in:

http://docs.oracle.com/cd/E24628_01/doc.121/e24473/plugin_mngr.htm

Adding Instances for Monitoring

After successfully deploying the plug-in, follow these steps to add the plug-in target to Cloud Control for central monitoring and management:

Log in to Enterprise Manager Cloud Control.
Click Setup, then Add Targets, and finally Add Targets Manually.
Select Add Non-Host Targets by Specifying Target Monitoring Properties. From the Target Type drop-down, select the EMC CLARiiON System target type. Click Add Manually.
Provide the following information for the parameters:
- Name — Name for the plug-in instance

- CLARiiON IP (SP A) — IP address of storage processor A
- CLARiiON IP (SP B)— IP address of storage processor B
- NaviCLI Host User—Name of the operating stem user enabled for executing naviseccli commands, for example oracle
- NaviCLI Host Password— Password for the operating system user
  
  Note:
  When specifying the NavisecCLI location, do not specify bin in the path name. The bin directory is appended when the PL scripts are run.
Click Test Connection to make sure the parameters you entered are correct.
Reenter the encrypted parameters from step 4 if the connection test was successful, then click OK.

Note:

After you deploy and configure the plug-in to monitor one or more targets in the environment, you can customize the monitoring settings of the plug-in. This alters the collection intervals and threshold settings of the metrics to meet the particular needs of your environment. If you decide to disable one or more metric collections, this could impact the reports that the metric is a part of.

Troubleshooting Scenarios

Some of the metrics do not show data or show metric collection error

Check if the version of NavisecCLI being used is supported and certified. Enterprise Manager supports NavisecCLI version 6.14 and higher.

Verifying the EMC CLARiiON plug-in is properly deployed

Run emc_clariion_response.pl as an agent user and check the output.

The command to execute the script is:

perl emc_clariion_response.pl
/opt/Navisphere <IP of SP A> Response

The location of the script is EMAGENT_HOME/sysman/admin/scripts/emx/emc_clariion_storage/.

If the output is as follows:

1 means it is fine.
0 means EMC CLARiiON is down. Check if it is up and NavisecCLI is configured.
error means NaviCLI is not properly configured. Follow the steps below.

Verifying the EMC CLARiiON agent is properly configured

Confirm NaviCLI is configured for the agent user by running:

/opt/Navisphere/naviseccli -h getagent

If not properly configured, an error will occur. If you see an error, do the following to isolate where the issue is:

Refer to Prerequisites to configure NavisecCLI.
Confirm that the user and password credentials are the same in the /etc/Navisphere/agent.config file and the user is logged into the NaviSphere GUI.
Verify the user/password used to configure NavisecCLI. (naviseccli AddUserSecurity -password mypass -scope 0 -user altusername)

Database reports do not show up

The database may not be configured for the agent monitoring the EMC CLARiiON target.

Verify by confirming that database shows up in the All Targets page.

Also, verify that no metric collection error is displayed for the database indicating the monitoring user name is correct.

Statistics data and graphs do not show any data

Statistics logging feature of the Navisphere software should be enabled to collect all the statistics data.

Verify by viewing properties of EMC CLARiiON in the Navisphere GUI. (Right-click on EMC CLARiiON to be monitored, enable Statistics logging.)

Clicking the Navisphere URL does not display the Navisphere GUI

Popup blocker should be disabled and JRE should be installed on the machine to enable running of the applets in the Navisphere.

Known Issues

Mapping of ASM diskgroups created using disks discovered through ASMLib for example, ORCL:*, is not supported.
Storage Groups Summary report does not display properly when EMC CLARiiON snapshot sessions are running.
