My z/VM wizard returned from share greatly excited to try swapping to DCSS.
He set up the segments and an EXEC that would properly define storage with
the gap. It was up to me to do the Linux part. With only a few stumbles I
got it running. There is one inconsistency. I set up the zipl.conf
parameter to specify dcss.segments=SWAP16M,<more segments> . The console
log says that the dcss.segments= parameter is invalid, yet it must be there
for swapping to DCSS to work. /proc/cmdline shows the entire parameter
string. Here is a snip from the console log:
Kernel command line: root=/dev/dasdb1 selinux=0 TERM=dumb elevator=cfq
vmpoff=LOGOFF
dcssblk.segments=SWAP16M,SWAP32M,SWAP64M,SWAP128M,SWAP256M,SWAP512M
BOOT_IMAGE=0
Unknown boot option
`dcssblk.segments=SWAP16M,SWAP32M,SWAP64M,SWAP128M,SWAP256M,SWAP512M':
ignoring
Here is my zipl.conf parameter string: parameters = "root=/dev/dasdb1
selinux=0 TERM=dumb elevator=cfq vmpoff=LOGOFF
dcssblk.segments=SWAP16M,SWAP32M,SWAP64M,SWAP128M,SWAP256M,SWAP512M "
This is SuSE SLES9 64-bit SP3 recently patched running on z/VM 5.2 on a
z900.
Can anyone explain it or tell me which organization I should notify?
Thanks,
tom

Toto, I have a feeling we're not in the mainframe world any more.
