yum grouplist not listing the package groups

Hi Guys,

I have just noticed that yum grouplist is not listing the package groups for base channel 'RHEL EUS (v. 6.3.z for 64-bit x86_64)'. Even you can see all repos available and enabled - group* commands are generating an error: 'no group data available configured repositories'.

Any suggestions will be welcomed. Thank you in advance.

Regards,

-Artur.
