Fabric Health Tab
Through Fabric Health tab, you can access the fabric health reports. There are two kinds of reports:
Custom Reports - The user can generate a report that runs a series of checks on the fabric on demand.
Periodic Reports - An automatically generated report that is periodically generated by the UFM.
Each check that is run for a report triggers a corresponding event. Events are also triggered when a report starts and ends. For more information, see Events & Alarms.
To run a new report, do the following:
Click “Run New Report."
Select the desired fabric health checks to run in the Fabric Health Report window and click “Run Report."
Results will be displayed automatically:
The report displays the following:
A report summary table of the errors and warnings generated by the report.
A fabric summary of the devices and ports in the fabric.
Details of the results of each check run by the report.
You can expand the view of each check or expand the view of all checks at once by clicking “Expand All."
To view only the errors of the report results, click the "Show Problems Only" checkbox.
The following table describes the checks included in the report.
Fabric Health Report Checks
Check | Description | To run, select: |
Duplicate/Zero LID Check | Lists all ports with same LID or zero LID value. | LIDs Check Default: Selected |
Duplicated Node Description | Lists all nodes with same node description. Does not include switches with the same description. | Duplicated Node Description Default: Selected |
Use Node GUID-Description Mapping | Enables the usage of a mapping file (between node GUID and node description) when running duplicate node description analysis of the fabric. This file is located on the UFM server side at: /opt/ufm/conf/sm_guid_desc_mapping.cfgconf/sm_guid_desc_mapping.cfg, and uses the following format (node_guid → description): 0x248a070300702710 "Desc1" 0x248a0703007026f0 "Desc2" 0x0002c90300494100 "Desc3" | Use Node GUID-Description Mapping Default: Unchecked Note: In order for this checkbox to be available, the Duplicated Node Description checkbox should also be selected. Otherwise, this checkbox will be greyed-out. |
SM Check | Checks that:
The report lists all SMs in the fabric with their attributes. | SM Configuration Check Default: Selected |
Bad Links Check | Performs a full-fabric discovery and reports “non-responsive” ports with their path. | Non-Optimal Links Check Default: Selected |
Link Width | Checks if link width is optimally used.
| None-Optimal Speed and Width Default: Selected Link Width: The default is ALL. |
Link Speed | Checks if link speed is optimally used.
| None-Optimal Speed and Width Default: Selected Link Speed: The default is ALL. |
Flapping Links Events | Provides a list of Links related events, generated by IBLR plugin. | Flapping Links Default: Not Selected |
BER Port Events | Provides a list of symbol BER related events, generated by IBLR plugin. | Symbol BER events Default: Not Selected |
Firmware Check | Checks for firmware inconsistencies. For each device model in the fabric, the test finds the latest installed version of the firmware and reports devices with older versions. | Firmware Version Check Default: Selected |
Health Policy Devices | Provides a list of defined UFM Health policy devices. | UFM Health Policy Default: Selected |
Cable Information | Reports cable information as stored in EEPROM on each port: cable vendor, type, length and serial number. | Cable Type Check & Cable Diagnostics Default: NOT selected because this test might take a long time to complete (40 msec per port) |
UFM Alarms | Lists all open alarms in UFM. | UFM Alarms Default: Selected |
The periodic reports are generated automatically upon UFM bring up.
To edit the report parameters, click the "Edit Report Parameters".
