You will have to use FBA and not DIAG on a 64-bit OS, at least until z/VM supports DIAG in that environment.

(LNG-DAY) Sent: Friday, September 22, 2006 12:27 PM To: [email protected] Subject: SWAPGEN EXEC and RHEL4 64-bit Hi all, I am looking for a way to pre-format a VDISK to be used as Linux swap space. I have come upon the SWAPGEN.EXEC at http://www.sinenomine.net/vm/swapgen and have a few questions. Linux Guest config on zVM 5.2: OS: 64-bit RHEL4 MEM: 4GB SWAP: 4 512MB VDISKs The verbiage on the sinenomine site makes me believe that I am unable to use the DIAG functionality of the SWAPGEN.EXEC since I am using a 64-bit Linux OS. Is this true? The recently published SLES9/RHEL4 Virtualization Cookbook Redbooks seem to be using the 64-bit versions of the Linux OS while still using the SWAPGEN.EXEC. 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)..." If I cannot use the "DIAG discipline", will the FBA/RXDASD still work with the 64-bit OS with 4GB of memory? Any feedback will be greatly appreciated.
