My mistake From Universal Server Admin Guide TAPESIZEonconfig.std value 10240 units kilobytes range of values Positive integers <<<<**************************** takes effect The value is read from the ONCONFIG file by ontape when it is executed. For onload and onunload, new values take effect when shared memory is initialized. ON-Monitor Parameters, Initialize, Total Tape Size (follows Tape Dev) On 32-bit machines this is 0K to 4294967295K i.e. 4Tb. Sorry! -- David Williams
