Error description
ABENDHTT001 occurs on source system during a VMRELOCATE when active I/O is present for relocating guest.
Local fix
Quiesce guest as much as possible prior to a relocation.
Problem summary
**************************************************************** * USERS AFFECTED: All z/VM users of the VMRELOCATE command * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** ABENDHTT001 occurs on the source system during the processing of the CP VMRELOCATE command for a guest. When an I/O interrupt is pending for a guest and IORBK information needs to be transferred to the destination system for that interrupt, invalid pointers in that IORBK can cause the system to abend with an ABENDHTT001.
Problem conclusion
ABENDHTT001 , D/T8561 ; The second level interrupt handler, HCPVIRPT, was modified to clear out the forward and backward pointers in the input IORBK (IORFPNT, IORBPNT). This will prevent live guest relocation from using invalid values in these fields which could cause an ABENDHTT001 or extraneous interrupt data from being transferred to the destination system.
