**************************************************************** * USERS AFFECTED: All users of PCI functions * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** Quick detach and reattach of PCI functions for guest operating systems was found to cause occasional HTT001 and SIT002 abends which were the result of mishandled PCI function control blocks.
Problem conclusion
Code was added in these cases to either restore addressability to or check the validity of the control blocks. This addressed the possible abend conditions.
