Hello Red Hat,
As mentioned this feature need to be blacklisted for R6.

Based on bug calls opened a separate BZ
LTC 60560  -  RIT498253- I/O dynamic configuration support for s390x needs to be blacklisted for RHEL6

Comment 4 IBM Bug Proxy 2010-06-25 06:20:40 UTC

The following BZ is verified OK:
LTC 60560  -  RIT498253- I/O dynamic configuration support for s390x needs to
be blacklisted for RHEL6
-> that verifies this feature is blacklisted in R6.

Further action to be evaluated for future R6 updates.

Based on that set this feature to verified for R6.
