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.
I know that Leland Lucius got DIAG working for 64-bit guests with less than 2GB of storage, but I don't know if that was ever rolled into the mainstream kernel or whether there's any way to make DIAG access work if you have more than 2GB.
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)..."
I believe this is still the case. Has it been fixed in a later release?
If I cannot use the "DIAG discipline", will the FBA/RXDASD still work with the 64-bit OS with 4GB of memory?
It should. I have never had the luxury of testing in that environment, but as long as you have the FBA driver you should be OK (presuming that VDISK works in an environment where your guest is > 2GB).
