Yes, they are using it in FBA mode. The problem lies in the fact that the necessary DIAG does not work in 64-bit mode on 64-bit zArchitecture systems, or at least not yet (Hey, Chuckie?). > Also, am I unable to use the DIAG functionality since my Linux Guest > machine has 4GB of memory? The following text from the same sinenomine > site leads me to believe this as well: "the DIAG discipline (which only > works for machines with < 2GB of virtual storage)..." The DIAG disk discipline only works in 31-bit machines, so >2G of storage is useless -- you can't address it. FBA works regardless of virtual machine size. > If I cannot use the "DIAG discipline", will the FBA/RXDASD still work > with the 64-bit OS with 4GB of memory? Yes, it does (and is the recommended method at this point for SWAPGEN on 64-bit systems).
