PowerFlex Management Platform - LAG Not Created On Existing DvSwitch's When Using Partial Network Automation (PNA)

Summary: A LAG is not created on dvSwitches while deploying a Resource Group using PNA.

This article applies to This article does not apply to This article is not tied to any specific product. Not all product versions are identified in this article.

Symptoms

If dvSwitches are created ahead of time in VC without LAG and the template calls for creating LAG, it will not be created.

PowerFlex 4.5.x automation script does not create LAG on dvSwitches if the template points to existing dvSwitches without LAG.

Deployment script fails

  • Confirmation that all switch settings are correct:
    • Dell OS10 switch port-channels / VLT
    • Cisco port-channel
  • After the resource group script fails, the user manually creates a lag in VC and migrates to it, a retry on the resource group is completed successfully.

The following is seen in thin-deployer logs:

Impact 

Deployment script fails if existing dvSwitch doesn't already have an LAG configured.

Cause

If the user selects "use existing" dvSwtiches, PFxM expects the existing dvSwitch configuration to work.

Even if the template calls for having an LAG configured, PFxM will not reconfigure the uplinks of an existing dvSwitch with an LAG.

Resolution

If PFxM creates the new dvSwitches, it will create the LAG successfully.

If dvSwitches are created ahead of time, the user should create LAG on them also.

If dvSwitches are created ahead of time and the user forgets to create LAG, then the script fails, manually create LAG in Vcenter / dvSwitches, migrate uplinks to them, then click "retry" on Resource Group.
