Cisco DCNM Fundamentals Guide, Release 10.2(x)

DCNM-SAN Server Features

Cisco DCNM-SAN Server has the following features:

• Multiple fabric management — DCNM-SAN Server monitors multiple physical fabrics under the same user interface. This facilitates managing redundant fabrics. A licensed DCNM-SAN Server maintains up-to-date discovery information on all configured fabrics so device status and interconnections are immediately available when you open the DCNM-SAN Client.
• Continuous health monitoring— MDS health is monitored continuously, so any events that occurred since the last time you opened the DCNM-SAN Client are captured.
• Roaming user profiles —The licensed DCNM-SAN Server uses the roaming user profile feature to store your preferences and topology map layouts on the server, so that your user interface will be consistent regardless of what computer you use to manage your storage networks.

Note You must have the same release of Cisco DCNM-SAN Client and Cisco DCNM-SAN Server.

Note You will not be able to manage a SAN fabric if the DCNM-SAN Server is going through a IP NAT firewall to access the SAN fabric. All the IP addresses that are discovered in a SAN fabric must be directly reachable by the DCNM-SAN Server.

DETAILED STEPS

Step 1 Install Cisco DCNM-SAN Client and Cisco DCNM-SAN Server on your workstation. See the “Installing Cisco DCNM-SAN Server”.

Step 2 Log in to DCNM-SAN.

Step 3 Set Cisco DCNM-SAN Server to continuously monitor the fabric. See the “Managing a Cisco DCNM-SAN Server Fabric”.

Step 4 Repeat Step 2 through Step 3 for each fabric that you want to manage through Cisco DCNM-SAN Server.

Step 5 Install DCNM-SAN Web Server. See the “Verifying Performance Manager Collections”.

Step 6 Verify Performance Manager is collecting data. See the “Verifying Performance Manager Collections”.

Installing Cisco DCNM-SAN Server

When you firsts install Cisco DCNM, the basic version of the Cisco DCNM-SAN Server (unlicensed) is installed with it. After you click the DCNM-SAN icon, a dialog box opens and you can enter the IP address of a computer running the Cisco DCNM-SAN Server component. If you do not see the Cisco DCNM-SAN Server IP address text box, click Options to expand the list of configuration options. If the server component is running on your local machine, leave localhost in that field. If you try to run DCNM-SAN without specifying a valid server, you are prompted to start the Cisco DCNM-SAN Server locally.

From Release 10.0(1), Cisco DCNM has supported to choose from the following options during installation. Based on the option you select, the application will be installed:

• DCNM Web Client
• DCNM SAN + LAN Client

To download the software from Cisco.com, go to the following website:

For detailed Cisco DCNM installation steps, please refer to

Cisco DCNM Installation Guide, Release 10.0(x).

Data Migration in Cisco DCNM-SAN Server

The database migration should be limited to the existing database. Data collision can occur when you merge the data between the several databases.

When you upgrade a non federation mode database to a federation mode database for the first time, the cluster sequence table is filled with the values larger than the corresponding ones in the sequence table and conforming to the cluster sequence number format for that server ID.

Verifying Performance Manager Collections

Once Performance Manager collections have been running for five or more minutes, you can verify that the collections are gathering data by choosing Performance Manager > Reports in DCNM-SAN. You see the first few data points gathered in the graphs and tables.

Selecting a Fabric to Manage Continuously

DETAILED STEPS

Step 1 Choose Server > Admin .

You see the Control Panel dialog box with the Fabrics tab ope.

Note The Fabrics tab is only accessible to network administrators.

Note You can preconfigure a user name and password to manage fabrics. In this instance, you should use a local switch account, not a TACACS+ server.

Step 2 Choose one of the following Admin options:

a. Manage Continuously —The fabric is automatically managed when Cisco DCNM-SAN Server starts and continues to be managed until this option is changed to Unmanage.

b. Manage —The fabric is managed by Cisco DCNM-SAN Server until there are no instances of DCNM-SAN viewing the fabric.

c. Unmanage — Cisco DCNM-SAN Server stops managing this fabric.

Step 3 Click Apply .

Note If you are collecting data on these fabrics using Performance Manager, you should now configure flows and define the data collections.

Cisco DCNM-SAN Server Properties File

The Cisco DCNM-SAN Server properties file ( MDS 9000\server.properties ) contains a list of properties that determine how the Cisco DCNM-SAN Server will function. You can edit this file with a text editor, or you can set the properties through the DCNM-SAN Web Services GUI, under the Admin tab.

Note As of Cisco NX-OS Release 4.1(1b) and later, you can optionally encrypt the password in the server.properties and the AAA.properties files.

The server properties file contains these nine general sections:

• GENERAL —Contains the general settings for the server.
• SNMP SPECIFIC —Contains the settings for SNMP requests, responses, and traps.
• SNMP PROXY SERVER SPECIFIC —Contains the settings for SNMP proxy server configuration and TCP port designation.
• GLOBAL FABRIC —Contains the settings for fabrics, such as discovery and loading.
• CLIENT SESSION —Contains the settings for DCNM-SAN Clients that can log into the server.
• EVENTS —Contains the settings for syslog messages.
• PERFORMANCE CHART—Contains the settings for defining the end time to generate a Performance Manager chart.
• EMC CALL HOME—Contains the settings for the forwarding of traps as XML data using e-mail, according to EMC specifications.
• EVENT FORWARD SETUP—Contains the settings for forwarding events logged by Cisco DCNM-SAN Server through e-mail.

The following server properties are added or changed in the Cisco DCNM-SAN Release 3.x and later.

SNMP Specific

• snmp.preferTCP —If this option is set to true, TCP is the default protocol for Cisco DCNM-SAN Server to communicate with switches. By default, this setting is true . For those switches that do not have TCP enabled, Cisco DCNM-SAN Server uses UDP. The advantage of this setting is the ability to designate one TCP session for each SNMP user on a switch. It also helps to reduce timeouts and increase scalability.

Note If you set this option to false, the same choice must be set in DCNM-SAN. The default value of snmp.preferTCP for DCNM-SAN is true.

Performance Chart

• pmchart.currenttime —Specifies the end time to generate a Performance Manager chart. This should only be used for debugging purposes.

EMC Call Home

• server.callhome.enable —Enables or disables EMC Call Home. By default, it is disabled.
• server.callhome.location —Specifies the Location parameter.
• server.callhome.fromEmail —Specifies the From Email list.
• server.callhome.recipientEmail —Specifies the recipientEmail list.
• server.callhome.smtphost —Specifies the SMTP host address for outbound e-mail.
• server.callhome.xmlDir —Specifies the path to store the XML message files.
• server.callhome.connectType —Specifies the method to use to remotely connect to the server.
• server.callhome.accessType —Specifies the method to use to establish remote communication with the server.
• server.callhome.version —Specifies the version number of the connection type.
• server.callhome.routerIp —Specifies the public IP address of the RSC router.

Event Forwarding

• server.forward.event.enable —Enables or disables event forwarding.
• server.forward.email.fromAddress —Specifies the From Email list.
• server.forward.email.mailCC —Specifies the CC Email list.
• server.forward.email.mailBCC—Specifies the BCC Email list.
• server.forward.email.smtphost —Specifies the SMTP host address for outbound e-mail.

Deactivation

• deactivate.confirm=deactivate —Specific Request for User to type a String for deactivation.

Note In a federated server environment, you should not change Cisco DCNM-SAN Server properties by modifying server.properties file. You must modify the server.properties using web client menu Admin > Configure > Preferences.
