New tools

  • 60-readahead.rules: udev rules to set increased "default max readahead".
    • The current "default max readahead" defined by the kernel is too small for s390. Add udev rule to set a better default value. This will increase sequential read performance up to 40%.

Changes to existing tools

  • lsqeth: Introduce "lay'2" column for "lsqeth -p" and new qeth attribute "isolation".
  • dumpconf: Prevent re-IPL loop for dump on panic.
    • A new keyword DELAY_MINUTES is introduced in the dumpconf configuration file. Using this keyword the activation of dumpconf can be delayed in order to prevent potential re-IPL loops.
  • qethconf: Indicate command failure and show message list.
    • When qethconf detects a bad exit status of its issued echo command, an error message is presented to the user.
    • Possible reasons for command failure can be listed with "qethconf list_msg".
  • zipl:
    • Improve I/O error recovery during IPL.
    • Automatically calculate the ramdisk address dependent on the kernel image size.
