Problem summary
**************************************************************** * USERS AFFECTED: Users that generate z/VM CP dumps. * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** This APAR addresses the following: (1) Depending on system settings, SYSTEM PGMBKs may not be included in CP dumps. This causes problems with the SPCON macro of the VM Dump Tool. (2) If CP is running as a second level system with more than 4 GB of storage and dump space is defined on VDISK, a SNAPDUMP can cause an ABENDHTT001 or ABENDSIT002 to occur, and system termination will fail with a 9276 disabled wait state. (3) HCPDMP savearea usage can produce misleading data, causing debugging problems. (4) If spool space for dump is on the first 65519 cylinders of an Extended Address Volume (EAV), a Fatal I/O error can occur when writing the dump. This prevents the dump from being created.
Problem conclusion
(1) PGMBK control blocks owned by SYSTEM are always included in dumps, which allows the SPCON macro in VM Dump Tool to work as expected. (2) This APAR cleans up 64 bit register usage in HCPDMP to avoid abends that may occur during SNAPDUMP on a second level system. (3) HCPDMP savearea usage is improved to provide better debugging information. (4) HCPDMP is updated to correctly compute the high cylinder number of the SPOOL space cylinders on an EAV device when a CP dump is being written to it.
