Ok, no shortage of spares here. So I tried it. Not good. dasdfmt of 10000 cyl - non PPRC non XRC - 1:55 ICKDSF of 10000 cyl - non PPRC non XRC - 1:13 LXFMT of 10000 cyl - non PPRC non XRC - 2:10
dasdfmt of 10000 cyl - PPRC, XRC'd - 5:00 ICKDSF of 10000 cyl - PPRC, XRC'd - 1:29 LXFMT of 10000 cyl - PPRC, XRC'd - 5:15 So, actually worse than dasdfmt.

Has anyone tried LXFMT for comparison? I don't have a spare pack to try at the moment, but from reading the code, it seems to know a few more tricks about the 390 I/O system, and might be a more workable alternative while the Germany folks figure out how to make dasdfmt smarter. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/ ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
