Error description
Customer experienced a SDV001 abend after a Unplanned Hyperswap was triggered and successfully completed. Normally, the 001 abend is a SOFT abend. But if encountered again while z/VM is in the middle of processing one of the same type, z/VM will treat the second as a HARD abend. This prevented the controlling system of the Hyperswap from completing the RESUME phase.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of z/VM * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** A hard ABENDSDV001 was taken due to several logical subsystems failing PPRC related recovery following an unplanned Hyperswap. Recovery I/O to these devices failed due to the problem which prompted the Hyperswap.
Problem conclusion
ABENDSDV001 The failing recovery is of the type that it could be deferred to a later time rather than taking the ABENDSDV001. The code for the abend will be removed which will allow the associated recovery routine to always complete without the previous risk of causing an outage for the entire system.
