CPO1166E   Target model name not possible with current On/Off CoD record

The ACTIVATE RESOURCE command with the CPC and MODEL parameters specified has been issued. You tried to activate temporary general purpose capacity but the CPC capacity does not allow activation of the requested model. You have either not enough capacity in the On/Off CoD record managed by the Provisioning Manager to move to the position, there are other capacity records active that do not allow moving to the requested model, or the requested model is not an allowed target model for the CPC. The activation is not processed.
