There is none.  Try to minimize or refrain from using "errdisable recovery" option.  This is even more important when used on a chassis-based system like the 6500/6800 and/or 4500 systems. 

If the ports went into error-disable this means something is wrong and is worth investigating.  To use "errdisable recovery" is akin to sweeping a potential problem under the carpet and is not a good practice.  This option only works well in a lab environment.  

Please advice more info or steps on how to investigating why the switches goes to err-disable state ?

Command:  sh interface status err

Your question is not very clear.  Can you explain in details what are you testing and what you are trying to do?
