Dynamic Port VSAN Membership Issues Chapter 11 Troubleshooting VSANs, Domains, and FSPF Send documentation comments to [email protected] DPVM Database Not Distributed Symptom DPVM databases are not distributed. Table 11-4 DPVM Database Not Distributed Symptom DPVM databases are not distributed. Possible Cause DPVM distribution has not been enabled on the local switch. DPVM distribution has not been enabled on one or more remote switches. Solution Choose Fabricxx > All VSANs > DPVM and select the CFS tab. Check the Global field in Fabric Manager or use the show dpvm status CLI command to verify that DPVM distribution is not enabled. Set the Global field to enable in Fabric Manager and then click Apply Changes or use the dpvm distribute CLI command to enable DPVM. DPVM Autolearn Not Working The DPVM autolearn feature allows you to automatically populate the DPVM configuration database with all devices currently in the fabric. This feature is best used when you first turn on DPVM in a stable fabric. Once the devices are learned, you disable autolearning to populate the configuration database with these autolearned entries. When you add a new device, it is a best practice to manually add that device to the DPVM configuration database. If you turn on autolearning for a new device, you may add other devices that you did not intend to add. Symptom DPVM autolearn does not work or is not getting enabled. Table 11-5 DPVM Autolearn Not Working Symptom Possible Cause Solution DPVM autolearn does not work or is not getting enabled. DPVM active database may be absent. Choose Fabricxx > All VSANs > DPVM and select the Active Database tab in Fabric Manager or use the show dpvm database CLI command to verify that DPVM is not enabled. Select the Actions tab and set the Action field to activate in Fabric Manager and then click Apply Changes or use the dpvm activate and dpvm commit CLI commands to create the DPVM active database. Note When DPVM distribution is enabled, you must do an explicit commit for DPVM activate and autolearn to take effect. 11-12 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x OL-9285-05
