z/VM 5.2 supports 64-bit DIAG and the March 28th update to the October 2005 kernel stream added Linux support for it. The steps for using it are discussed in the Device Drivers manual.
Sadly that means you'll need RHEL 5 since 4.4 is based on the 2004 stream. ks On 9/22/06, Post, Mark K <[EMAIL PROTECTED]> wrote:
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.
