Collecting Virtual Storage-to-SAN Relationships

To include virtual storage-to-SAN relationships in your topology diagrams, you need to enable storage collection on your VMware or Hyper-V Performance agent. If you did not enable this option when defining the agent, you can enable it by editing the agent.

 
* 
NOTE: If you cannot see the Administration dashboards, ask your Foglight for Storage Management Administrator to add the role VMware Administrator or Hyper-V Administrator to your user account.
To update an existing virtualization agent to add the collection of storage data:
1
On the navigation panel, under Dashboards, click VMware > VMware Agent Administration or Hyper-V > Hyper-V Agent Administration.
2
In the Agents table, locate the Agent. In the Data Collection column, you can see whether general data collection is enabled for this agent. Storage data collection, however, is not enabled by default.
3
To enable storage data collection for an agent, click the agent’s Edit icon.
4
Select the Enable Storage Collection check box and click Save.

Inferring Physical-Host-to-Storage Relationships

If you want to understand how storage resources are being accessed by the physical hosts in your network, without using agents to monitor the hosts directly, you can enable dependency processing. Dependency processing collects FC switch zone information and LUN connection information from arrays and filers, analyzes each host port used for storage I/O, and infers the (most likely) physical host associated with the port. When dependency processing is enabled, relevant topology diagram are enhanced to show inferred hosts connected to the ports that are used for storage I/O. Connections from inferred hosts are shown as orange or blue lines.

Figure 9. SAN Topology tab

In future, if you decide you want to collect data about inferred physical hosts, you can begin monitoring the hosts by configuring Infrastructure agents. For instructions, see Reviewing Inferred Hosts.

Enabling Dependency Processing

Dependency processing requires that you have VMware Performance agents configured to monitor your vCenters, and that storage collection is enabled on the agents. For more information, see “Configuring VMware Performance Agents” in the Foglight for Storage Management Installation Guide.

To enable dependency processing:
1
On the navigation panel, under Dashboards, click Storage & SAN > Storage Environment.
2
Click the Administration tab.
3
Click Enable Physical Host to Storage Dependency Processing.
4
In the Physical Host Support message box, click Yes.
The dependency processing algorithm collects information and runs a host-resolution process. This may take some time.
When the processing completes, the Enable Physical Host to Storage Dependency Processing Task changes to Disable Physical Host to Storage Dependency Processing Task, and a new task, Review Physical Host FQDNs, appears in the task list.

Next Step: Reviewing and Editing Host-Port Assignments

Reviewing and Editing Host-Port Assignments

After enabling dependency processing, it is a good idea to review the list of inferred hosts derived from this process. You can verify that the inferred hosts are correct for the specified port, fix errors, and provide missing host names. For this task, you use the Review Physical Host FQDNs dashboard.

 
* 
NOTE: The Review Physical Host FQDNs dashboard also contains host-port assignment for physical hosts that are being monitored by an agent.
To review the list of hosted identified by dependency processing:
1
On the Storage Environment dashboard, in the Administration tab, click Review Physical Host FQDNs.
The Review Physical Host FQDNs dashboard opens. The table displays the list of hosts, the associated port carrying storage I/O, zone information for switch ports, and the number and type of storage resources accessed. You can filter the contents of the table using the Show Host Ports check boxes.
 
2
To add missing host names or change existing host names:
a
Click the row check boxes for the port assignments you want to change. All selected ports will be assigned the same host name.
b
Click Edit Host FQDN.
c
Type the fully qualified domain name for the host, and click Submit.
The table displays the new host-port assignments.
3
To remove host assignments from ports, select the row check boxes for the ports and click Clear Host FQDN.
•
Clearing a user-resolved host makes the agent-resolved host active, if one exists.
•
Clearing an agent-resolved host adds the host FQDN to a list so that it does not get reassigned to the port in the future.
