Issue/Introduction

Symptoms:

When running vSphere 5.5 with Virtual Distributed Switches (vDS), you experience these symptoms:

• Cannot import a vDS to a vCenter Server
• Importing a Distributed Switch fails
• LACP enhanced mode upgrade was performed at some point
• In the vpxd log file, you see entry similar to:
  
  YYYY-MM-DD TIME.558+01:00 [00628 error 'featurelacp' opID=32639d2c] [Lacp::ValidateLacpInDvpgConfig] Enabling or updating single lag is not allowed as lacpApiVersion is [multipleLag]. 2014-06-11T12:07:06.564+01:00 [00628 error 'featurelacp' opID=32639d2c] [Lacp::ThrowApiConflict] lacpApiVersion [multipleLag] conflicts with the configuration of lag on the vds 2014-06-11T12:07:06.674+01:00 [00628 error 'dvsvpxdMoDvsManager' opID=32639d2c] [MoDvsManager::CreateNewEntity] Import Failed while creating DVS from Backup with key[47 52 13 50 cb a9 d8 85-c1 5a b6 7e 92 33 a4 df]. Fault:[vim.fault.ConflictingConfiguration]

Cause

The issue occurs due to a problem with the Virtual Distributed Switches (vDS) upgrade process, which does not handle the LACP version upgrade correctly.

Resolution

This is a known issue affecting upgraded vDS switches in vCenter Server 5.5. Currently there is no resolution.

To work around this issue, a modification of the vCenter Server database is required to make the switch export correctly.

To modify the database and allow correct vDS export:

1. Log in to the source vCenter Server database using SQL management studio
2. Run this SQL script prior to exporting the vDS switch:

update VPX_DVPORT_SETTING

set VPX_DVPORT_SETTING.LACP_ENABLE = NULL, VPX_DVPORT_SETTING.LACP_MODE = NULL

from VPX_DVPORT_SETTING B

inner join VPX_DVS A

on A.ID = B.DVS_ID AND A.PRODUCT_VERSION = '5.5.0' AND A.LACP_API_VERSION = 'multipleLag';
