Operating system or partition requirements
If you are installing a new feature, ensure that you have the software that is required to support the new
feature and that you determine whether any prerequisites must be met for this feature and attaching
devices. To check for operating system and partition requirements, see one of the following links:
v The latest version of enabling libraries and utilities can be downloaded from Fix Central
(http://www.ibm.com/support/fixcentral/).
v IBM Power Systems Prerequisites (https://www14.software.ibm.com/support/customercare/iprt/
