View network or storage path

You can drill down to see objects behind a connection on a business service map for troubleshooting service performance or maintaining your network.

Role required: admin, sm_admin or sm_user

About this task

Displaying a network or storage path allows you to see routers, switches, and host ports which are part of the connection. The following connection types exist:
Network path
The infrastructure route between two CIs of the host type.
Storage path
The infrastructure route between a CI of the host type and a CI of the storage type.

Service Mapping discovers and displays network devices located on your organization local network, not on WAN or the public cloud. When Service Mapping encounters a connection between two applications, it uses traceroute on the source host to figure out the path to the target host. Then Service Mapping use SNMP credentials to discover the devices it found on the path.

Service Mapping can show devices for storage paths using the following protocols: Fiber Channel (SAN) and IP Ethernet (iSCACI or NAS).
Note: For storage paths using Fiber Channel, Service Mapping does not display Fiber Channel switches.

Between a host CI and a storage CI there may be two separate storage paths using different protocols: Fiber Channel and IP Ethernet. If so, the business service map displays one connection line for both protocols.

You can see the change history for network and storage paths for business services. Checking path history for manual or technical services is not supported.

Procedure

  1. Navigate to Service Mapping > Services > Business Services and click View map next to the relevant business service.
    Or
  2. Navigate to Event Management > Dashboard and double-click a business service.
  3. On the map, right-click the connection for the network or storage path you want to see.
  4. Select Show network path or Show storage path.
  5. If necessary, select the type of protocol and click Choose in the Choose Protocol Type dialog box.
    The view showing the network or storage path opens in a new tab.


    If Service Mapping cannot discover all objects in a connection, the connector line on the network or storage path appears dotted as shown above.

  6. For storage paths, use the Storage Mapping tab at the bottom of the screen to view correlation between file systems on the host and the storage volume or the shared folder on the storage device.
  7. To view the change history for network paths, perform steps in View change history of business services.
  8. If you access the network or storage path map from Event Management, you can see the list of alerts related to this path appear at the bottom of the screen.
