(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 5.9/5.10, Patch 7005747 is applied to agent version 10.2.0.4.0 on Solaris 5.9 and 5.10. 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

After you ensure that the prerequisites are met, follow these steps to deploy the plug-in:

Download the EMC Symmetrix DMX System Plug-in archive to your desktop or computer on which the browser is launched. You can download the archive from the Oracle Technology Network (OTN).
Log in to Enterprise Manager Grid Control as a Super Administrator.
Click the Setup link in the upper right corner of the Grid Control Home page, then click the Management Plug-ins link on the left side of the Setup page.
Click Import.
Click Browse and select the plug-in archive.
Click List Archive, which lists the plug-ins from the selected archive.
Select the plug-in and click OK.
Verify that you have set preferred credentials on all Agents where you want to deploy the plug-in.
In the Management Plug-ins page, click the icon in the Deploy column for the EMC Symmetrix Storage System plug-in. The Deploy Management Plug-in wizard appears.
Click Add Agents, then select one or more Agents to which you want to deploy the plug-in. The wizard reappears and displays the Agent you selected.
Click Next, then click Finish.

If you see an error message stating that the preferred credential is not set up, go to the Preferences page and add the preferred credentials for the Agent target type.

Adding Instances for Monitoring

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

From the Agent home page where the EMC Symmetrix DMX System Plug-in was deployed, select the EMC Symmetrix DMX System target type from the Add drop-down list, then click Go.

The Add EMC Symmetrix DMX System page appears.
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 2 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

For security reasons, Oracle recommends that the SYSMAN account be used only as a template to create other accounts, and not used directly.

Therefore to manage the 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.

Follow the steps provided in this section to provide management rights to users.

As SYSMAN, log in to Enterprise Manager Grid Control.
Click Setup.

The Setup page appears.
To create roles, click Roles. Click Help for assistance.
To create administrators, click Administrator. Click Help for assistance.

When the newly created administrator logs in, unlike SYSMAN, the administrator is restricted by the privileges set.

Example 1

Susan, the super administrator wants to let Maria view target database instance sifsdb.

When Maria accesses the reports, if privileges are not set for Maria to view database target, the rows for sifsdb will not be displayed in the report. Therefore, for Maria to view sifsdb, Susan has to set privileges as illustrated below:

Susan launches Enterprise Manager Grid Control and then in the Setup page, selects Roles.
She uses the Create Roles page to create a role for assigning to Maria.
In the Create Role Properties page, she specifies the name of the role as Maria_Role.
In the Create Role: Roles page, she chooses an existing role for Maria.
In the Create Roles System Privileges page, she chooses the system privileges for Maria.
In the Create Roles Targets page (Figure 1) Susan selects the target sifsdb from the list of Available Targets.

Figure 1 Select Targets
In the Create Role Target Privileges page (Figure 2) she selects View privileges for the role, so that Maria (when assigned with this role) has the rights to view the target.

Figure 2 Target Privileges
In the Create Role Administrator page (Figure 3) she grants Maria the role.

Figure 3 Create Role

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

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 Symmetrix DMX System 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 Symmetrix DMX System Plug-in.

The Undeploy Management Plug-in page appears.
Check all the Agents that are currently deployed with the EMC Symmetrix DMX System 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 Symmetrix DMX System Plug-in on the Management Plug-ins page and click Delete.
