Upgrade vDS from 4.0 to 4.1 Error

[CSHAW78]

I am upgrading our vDS switches from 4.0 to 4.1 . I am getting the following error

XXX com.vmware.vim.vpxd.dvs.upgradeNotAllowedoldVersion.label not found XXX

Does anyone have any ideas ?

Do you have any hosts running 4.0 attached to the dvSwitch?

Hi Chris,

All hosts are running 4.1 U1 , the upgrade includes a compatablitity check and this all comes back clean.

This has been resolved .. Long hard search through the VC logs and one of the host wasn't responding to the upgrade. Restarted the management agent and all is fine now.
