Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of the HYPERSWAP QUIESCE command * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** An HTT001 abend could occur during HYPERSWAP QUIESCE commands that have incorrect RDEV specifications leading to error messages. This would only occur following the successful quiesce of a previous device as that would cause the loss of a control block pointer.
