This feature provides interfaces to change LPAR IOCDS dynamically and persistent

3. Business Case
This feature will allow Linux-on-LPAR-only customers as soon as a userspace tool, to not have to
extra install z/VM or z/OS to be able to dynamically change IOCDs and not to do IML of the machine,
which will benefit availability and costs for customers.

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 02:20:40 EDT
------- Comment From mgrf@de.ibm.com 2010-06-25 02:10 EDT-------
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.
