Description

The System Monitoring Plug-in for EMC Symmetrix DMX System extends Oracle Enterprise Manager Cloud Control to add support for monitoring EMC Symmetrix DMX System. By deploying the plug-in in your Cloud Control environment, you gain the following management features:

Monitor EMC Symmetrix DMX Systems.
Gather storage configuration and performance information of various storage components.
Raise alerts and violations based on thresholds set on monitored metrics and configuration data.
Generate rich out-of-box reports based on the gathered data. For details of reports, see Reports.
Monitor using a remote Agent. For remote monitoring, the Agent need not be on the same host as the EMC Symmetrix DMX 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 Symmetrix DMX System Plug-in can only be deployed on Linux and Solaris, not Microsoft Windows. Refer to WebIV Note 465472.1 for the latest certification status on different platforms.
EMC Solutions Enabler versions 6.4, 6.5, and 7.0

Prerequisites

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

Oracle Enterprise Manager Cloud Control 12c Release 1 or higher
EMC Solutions Enabler version 6.4 or 6.5 or 7.0
Oracle Management System (OMS) version 10.2.0.3 or higher with relevant patches
An OS user is created, for example symm_user
Ensure that the file daemon_users is available in the following install directory of SYM CLI:

/usr/emc/API/symapi/config/
Note:
If the daemon_users is not available,
1. Create the file daemon_users file in the SYMCLI install directory (for example /opt/emc/SYMCLI/V6.2.1/storbin/stordaemon).
2. In the file, specify the following:
  
  username storapid, for example symm_user storapid
3. Restart stordaemon by entering the following command:
  
  ./stordaemon start<daemon name>
  
  where daemon names are storapid, storwatchd, storgnsd
(For Enterprise Manager 10.2.0.3) Patch 5844887 is applied on OMS to enable filtering of data in the reports
(For Enterprise Manager 10.2.0.3) Patch 5842718 is applied on agent to enable the appearance of front-end adapter information along with Symmetrix 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 Symmetrix DMX System 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 Symmetrix DMX System 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 Symmetrix DMX System target type. Click Add Manually.
Provide the following information for the parameters:
- Name — Name for the plug-in instance
- SYMCLI Location — Install location of SYMCLI, for example /usr/symcli
- Symmetrix ID — 12-digit Symmetrix ID
- SYMCLI Host User— Name of the OS user enabled for executing SYMCLI commands, for example symm_user
- SYMCLI Host Password— Password for the OS user
- (Optional) EMC Symmetrix Management Console URL— The Symmetrix Management Console URL
Note:
When specifying the SYMCLI 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.

Managing the Plug-in

To manage the EMC Symmetrix DMX System plug-in, you need to create roles and administrators, and then assign roles to administrators. This restricts the privileges that each user has, for example deleting the plug-in or accessing reports.

To create a Role or Administrator account:

Log in to Enterprise Manager Cloud Control.
Click Setup, then Security. Select Role to create a role or Administrator to create an administrator account.
Enterprise Manager Cloud Control provides predefined accounts that you can use to customize an account. Select a name and click Create Like to begin. You will provide information for:
- Properties: information about the account
- Roles: select appropriate roles for the account from a list of available roles
- Target Privileges: the target privileges you want to assign to the account
- Resource Privileges: specific privileges to be explicitly granted on "all resources" level or individual resources to grant
Once you enter the information on each page, a Review page provides a summary of your selections.
Enter Properties information:
- For an Administrator account, enter:
  - Name
  - Password and Confirm Password
  - Select a Password Profile, and select the password options
  - E-mail address for the administrator
  - Description
- For a user Role, enter:
  - Name
  - Description (optional)
Once the information is complete, click Next.
On the Roles page, select one or more roles from the list of Available Roles. Click Move to add the role to the account.

Once you have completed adding the appropriate role, click Next.
On the Target Privileges page, select the privileges you want to assign to the account. The privileges are applicable to all targets.

Once you have completed adding the appropriate target privileges, click Next.
On the Resource Privileges, identify specific privileges to be explicitly granted on "all resources" level or individual resources to grant. Click the Manage Specific Grants edit icon to modify the privileges.
On the Review page, verify the information you entered is correct. Click Finish to create the account.

Verifying and Validating the Plug-in

After waiting a few minutes for the plug-in to start collecting data, use the following steps to verify and validate that Enterprise Manager is properly monitoring the plug-in target:

Click the EMC Symmetrix DMX System target link from the Agent home page Monitored Targets table.

The EMC Symmetrix DMX System home page appears.
Verify that no metric collection errors are reported in the Metrics table.
Ensure that reports can be seen and no errors are reported by selecting the Reports property page.
Ensure that configuration data can be seen by clicking the View Configuration link in the Configuration section.

If configuration data does not immediately appear, click Refresh in the View Configuration page.

Undeploying the Plug-in

To undeploy the EMC Symmetrix DMX System Plug-in from an Agent:

Log in to Enterprise Manager Cloud Control as root.
Click Setup, then Extensibility, and finally Plug-ins.
Select the EMC Symmetrix DMX System Plug-in target and click Undeploy From. Select either Management Servers or Management Agent.
Confirm the plug-in removal. Enterprise Manager notifies the connected and relevant Enterprise Manager users and begins the de-configuration process.

For more information about plug-ins, see the Plug-in Manager chapter in the Oracle Enterprise Manager Cloud Control Administrator's Guide:

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