Information About DCNM-SAN Client

Cisco DCNM-SAN is a Java and SNMP-based network fabric and device management tool with a GUI that displays real-time views of your network fabric, including Cisco Nexus 5000 Series switches, Cisco MDS 9000 Family and third-party switches, hosts, and storage devices.

In addition to complete configuration and status monitoring capabilities for Cisco MDS 9000 Family switches and Cisco Nexus 5000 Series switches, Cisco DCNM-SAN Client provides Fibre Channel troubleshooting tools. You can use these health and configuration analysis tools on the MDS 9000 Family switch or Cisco Nexus 5000 Series switch to perform Fibre Channel ping and traceroute.

Cisco DCNM-SAN Release 4.1(1b) and later provides multilevel security system by adding a server admin role that allows access to limited features. The configuration capabilities of a server admin is limited to FlexAttach and relevant data.


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


Cisco DCNM-SAN Advanced Mode

Advanced mode is enabled by default and provides the full suite of Cisco DCNM-SAN features, including security, IVR, iSCSI, and FICON. To simplify the user interface, from the list box in the upper right corner of the Cisco DCNM-SAN Client, choose Simple. In simple mode, you can access basic MDS 9000 features such as VSANs, zoning, and configuring interfaces. Advanced mode option is not available for server admin role.

Cisco DCNM-SAN Client Quick Tour: Server Admin Perspective

Cisco DCNM-SAN provides a multilevel security system by adding a server admin role that allows access only to limited features. The configuration capabilities of a server admin role is limited to FlexAttach and relevant data. The server admin can pre-configure SAN for new servers, move a server to another port on the same NPV device or another NPV device and replace a failed server onto the same port without involving the SAN administrator. The server role admin will not be able to manage Cisco DCNM-SAN users or connected clients.

Cisco DCNM-SAN provides a much improved user interface by including movable and dockable panes to let users arrange the Physical Attributes pane, Logical Domains pane, Fabric pane and Information pane according to requirements, making it easier to manage the workflow. The dockable panes are also called as dockable frames. A dockable frame can be standalone (floating), minimized or maximized. The logical, physical, information and the fabric panes can be can be collapsed and expanded as needed. These panes can also be docked at either the right side left side or to the bottom of the workspace.

The Fabric pane has its own toolbar with options for saving, printing, and changing the appearance of the map. When you right-click the map, a pop-up menu appears that provides options (duplicated on the toolbar) for changing the appearance of the map.


Note You can launch web-based or non-web-based applications from the Fabric pane. To do this, you assign an IP address to the storage port or enclosure. Then right-click to bring up the pop-up menu, and select Device Manager.


Saving the Map

You can save the map in the Fabric Pane as an image, or as an editable Visio diagram. You can save the map with or without labels on the links. The created Visio diagram is editable and saved in two layers:

  • The default layer includes all switches and links in the fabric.
  • The end devices layer includes the end devices and can be turned off to remove end devices from the Visio diagram.

To save the map as a Visio diagram, choose Files > Export > Visio and choose Map or Map with link labels. The saved Visio diagram retains the viewing options that you selected from the Fabric pane. For example, if you collapse multiple links in the map and export the links as a Visio diagram, the Visio diagram shows those multiple links as one solid link.

The Show Tech Support option from the Tools menu also supports saving the map as a Visio diagram.

Purging Down Elements

The Fabric pane allows you to refresh the map at any time by clicking the Refresh Map icon. The Refresh Map icon redraws the map but does not purge elements that are down. To purge down elements you can:

  • Choose Server > Purge Down Elements. This purges all down elements in the fabric.
  • Right-click the Fabric pane and choose Purge Down Elements.
  • Right-click a down element and choose Purge. This action purges only this element from the fabric.

Note If you select an element that is not down and purge it, that element will reappear on the next fabric discovery cycle.


Multiple Fabric Display

Cisco DCNM-SAN can display multiple fabrics in the same pane.

The information for both fabrics is displayed; you do not need to select a seed switch. To see details of a fabric, select the tab for that fabric at the bottom of the Fabric pane, or double-click the Cloud icon for the fabric in the SAN tab.


Note Enclosure names should be unique. If the same enclosure name is used for each port, Cisco DCNM-SAN shows a host/target enclosure connected to both fabrics. To fix this problem, you can either disable auto-creation or create unique enclosure names.

If you enable this preference, you can detach the overview window and move it to one side while you access the Fabric pane. The default setting for this value is disabled (unchecked).

Network Fabric Discovery

Cisco DCNM-SAN collects information about the fabric topology through SNMP queries to the switches that are connected to Cisco DCNM-SAN. The switch replies after having discovered all devices connected to the fabric by using the information from its FSPF technology database and the Name Server database and collected using the Fabric Configuration Server’s request/response mechanisms that are defined by the FC-GS-3/4 standard. When you start Cisco DCNM-SAN, you enter the IP address (or host name) of a seed switch for discovery.

After you start Cisco DCNM-SAN and the discovery completes, Cisco DCNM-SAN presents you with a view of your network fabric, including all discovered switches, hosts, and storage devices.

Network LAN Discovery

Starting from NX-OS Release 4.2(0), you can discover Nexus and Catalyst Ethernet switches using Cisco Discovery Protocol (CDP). DataCenter 3(DC3) switches are displayed under Datacenter and LAN nodes. Cisco DCNM-SAN displays basic information about DC3 switches and its ISLs.

Viewing Ethernet Switches

DETAILED STEPS


Step 1 Click the LAN node under Datacenter node.

Step 2 Click Switches tab in the Information pane.

Step 5 Press Ctrl-C to copy the selected name(s).

Step 6 Press Ctrl-V to paste the device name into the Name field.


Note To remove devices from an enclosure, triple click the device name and press Delete. To remove an enclosure, repeat this step for each device in the enclosure.



 

Using Alias Names as Enclosures

DETAILED STEPS


Step 1 Expand End Devices and choose Hosts or Storage from the Physical Attributes pane.

You see the list of devices in the Information pane. The NxPorts tab is the default.

Step 2 Right-click the enclosure names that you want to convert to alias names and choose Alias > Enclosure .

The Ailas > Enclosures window appears . It contains a list of expressions. You can also add expressions to the list and modify expressions in the current list.

Step 3 Click the Apply Changes icon to save the changes and then click Close.


Note Cisco DCNM-SAN uses the regular expressions to convert multiple alias names into one enclosure. The alias names should be in the same expression pattern rule. You can create enclosure names from selected aliases using the regular expresssions list.



 

Using Alias Names as Descriptions

DETAILED STEPS


Step 1 Choose End Devices and from the Physical Attributes pane.

Step 2 Click the General tab.

You see the list of devices in the Information pane.

Step 3 Select the device names that you want to populate the description with alias names and then click Alias > Enclosure button .

You see the alias names are copied to corresponding rows in the description column.


Note Cisco DCNM-SAN does not parse or format the alias name while copying.



 

Controlling Administrator Access with Users and Roles

Cisco MDS 9000 Family switches support role-based management access whether using the CLI or Cisco Cisco DCNM-SAN. This lets you assign specific management privileges to particular roles and then assign one or more users to each role.

The default-role contains the access permissions needed by a user to access the GUI (Cisco DCNM-SAN and Device Manager). These access permissions are automatically granted to all users in order for them to use the GUI.

Cisco Cisco DCNM-SAN uses SNMPv3 to establish role-based management access. After completing the setup routine, a single role, user name, and password are established. The role assigned to this user allows the highest level of privileges, which includes creating users and roles. Use the Cisco Cisco DCNM-SAN to create roles and users and to assign passwords as required for secure management access in your network.

Using Cisco DCNM-SAN Wizards

Cisco DCNM-SAN Client provides the following wizards to facilitate common configuration tasks:

  • VSAN—Creates VSANs on multiple switches in the fabric and sets VSAN attributes including interop mode, load balancing, and FICON.
  • Zone Edit Tool—Creates zone sets, zones, and aliases. Adds members to zones and edits the zone database.
  • IVR Zone—Creates IVR zone sets, zones, and aliases. Enables IVR NAT and auto-topology. Adds members to IVR zones, and edits the IVR zone database.
  • FCoE—Creates virtual Fibre Channel (FC) interfaces and VLAN-VSAN mappings, and binds virtual FC interfaces to Ethernet interfaces or PortChannels.
  • PortChannel—Creates PortChannels from selected ISLs either manually or automatically. Sets PortChannel attributes such as channel ID and trunking mode.
  • FCIP—Creates FCIP links between Gigabit Ethernet ports. Enables Fibre Channel write acceleration and IP compression.
  • DPVM—Establishes dynamic port VSAN membership, enables autolearning, and activates the DPVM database.
  • Port Security—Prevents unauthorized access to Cisco MDS switches and reports these intrusions to the administrator.
  • iSCSI—Creates zones for iSCSI initiators and adds a VSAN to a target-allowed VSAN list.
  • NPV—Reduces the number of Fibre Channel domain IDs in SANs.
  • QoS—Sets QoS attributes for zones in the selected VSAN.
  • IP ACL—Creates ordered IP access control lists and distributes to selected switches in the fabric.
  • License Install—Facilitates download and installation of licenses in selected switches in the fabric.
  • Software Install—Verifies image compatibility and installs software images on selected switches in the fabric.

Cisco DCNM-SAN Troubleshooting Tools

Cisco DCNM-SAN has several troubleshooting tools available from the toolbar or Tools menu

  • Zone Merge Analysis —The zone merge analysis tool (available from the Zone menu) enables you to determine if zones will merge successfully when two Cisco MDS switches are interconnected. If the interconnected switch ports allow VSANs with identical names or contain zones with identical names, then Cisco DCNM-SAN verifies that the zones contain identical members. The merge analysis tool can be run before attempting a merge or after fabrics are interconnected to determine zone merge failure causes.
  • End-to-End Connectivity —Cisco DCNM-SAN’s end-to-end connectivity analysis tool uses FC Ping to verify interconnections between Cisco MDS switches and end-device (HBAs and storage devices) in a particular VSAN. In addition to basic connectivity, Cisco DCNM-SAN can optionally verify the following:

Paths are redundant.

Zones contain at least two members.

End devices are connected to a manageable switch (have a currently active in-band or out-of-band management path.)

  • Switch Health Analysis —You can run an in-depth switch health analysis with Cisco DCNM-SAN. It verifies the status of all critical Cisco MDS switches, modules, ports, and Fibre Channel services. Over 40 conditions are checked. This tool provides a very fast, simple, and thorough way to assess Cisco MDS switch health.
  • Fabric Configuration Analysis —Cisco DCNM-SAN includes a fabric configuration analysis tool. It compares the configurations of all Cisco MDS switches in a fabric to a reference switch or a policy file. You can define what functions to check and what type of checks to perform. The analysis can look for mismatched values, and missing or extra values. If all configuration checking is performed for all functions, over 200 checks are performed for each Cisco MDS switch.

After the analysis is run, the results are displayed with details about the issues that were discovered. You can automatically resolve configuration differences by selecting them and clicking the Resolve button. Cisco DCNM-SAN automatically changes the configuration to match the reference switch or policy file.

Integrating Cisco DCNM-SAN and Data Center Network Management Software

Cisco DCNM-SAN and Data Center Network Management (DCNM) software are the two major components in the Cisco next-generation data center environment. Cisco DCNM-SAN configures Cisco Nexus 5000 Series switches and Cisco MDS 9000 Series switches. DCNM software configures Cisco Nexus 5000 and Cisco Nexus 7000 Series switches. The Scope of the Cisco DCNM-SAN software is confined to SAN while the scope of the DCNM-LAN software is limited to the LAN network.

In a typical data center environment, the mixture of SAN and LAN topology are becoming increasingly common. Since the two management software are not designed to work across their topology limits, users are not able to navigate to Cisco DCNM-SAN from DCNM-LAN software and vice versa.

Integrating Cisco DCNM-SAN and DCNM-LAN provides a single platform to manage the networks in data center 3.0 and it provides seamless user experience under specific configuration. Starting from Cisco MDS NX-OS Release 4.2, the directory structure has changed to accommodate the integration of Cisco DCNM-SAN with Cisco Nexus 5000 Series products.
