New tools

  • ipl_tools:
    • chreipl: Change reipl device settings.
    • chshut: Change actions which should be done in case of halt, poff, reboot or panic.
    • lsreipl: List information of reipl device.
    • lsshut: List actions which will be done in case of halt, poff, reboot or panic.
  • ziomon tools:
    • Set of tools to collect data for zfcp performance analysis.
      Use of this support requires zfcp-support in kernel 2.6.27 with patch 01 as well as blktrace 1.0.0 (or later)
  • lsluns: List available SCSI LUNs depending on adapter or port.
  • lszcrypt: Show information about zcrypt devices and configuration.
  • chzcrypt: Modify zcrypt configuration.

Changes to existing tools

  • ip_watcher: New qeth driver support.
    • Adapt ip_watcher to support the sysfs interface of the qeth driver.
      This is necessary because of the changes in the qeth driver (with kernel 2.6.26).
  • lscss:
    • lscss now shows non I/O subchannels.
    • Added new options to limit the output to ranges of subchannels or devices.
  • lstape: Add SCSI tape support.
    • With this feature it is now possible to list installed FCP-attached tape devices (SCSI tapes) besides channel attached tapes.
  • osasnmpd: New qeth driver support.
    • Adapt osasnmpd to changes in the qeth driver (with kernel 2.6.26), which does no longer offer the sysfs attribute notifier_register.
    • Notification of added or removed OSA-cards now has to be done in user space (udev). The udev rule file '57-osasnmpd.rules' is now provided in the s390-tools package.
  • zfcpdump_v2:
    • Add support for memory holes: zfcpdump was not prepared to deal with multiple, non-contiguous storage extents. This shortcoming has been fixed by introducing a new debugfs file zcore/memmap which contains information on start address and length of memory chunks. With z/VM 5.4 it is possible to dump Linux on System z VM-guests to FCP-attached SCSI-disks, which requires zfcpdump-support for memory holes - because z/VM allows to have discontiguous memory.
    • Update to latest e2fsprogs (1.41.3) and kernel (2.6.27) versions.
  • zipl: Support for virtio devices.
    • This feature allows zipl to prepare virtio devices for IPL and dump.
  • zipl dump tools:
    • Multi volume dump support for DASDs: The ability to dump on multiple ECKD DASD devices, which can be necessary, if the system memory size is larger than the size of a single DASD device.

Bug fixes

  • cpuplugd:
    • Fix "Required Start/Stop" dependencies.
    • A bug which prevented CPUs from beeing set online again after /etc/init.d/cpuplugd reload and restart has been fixed.
  • lsdasd:
    • Correct presentation of DASD HPAV alias devices.
    • Improve performance of script.
    • Correct bug with non-privileged users.
    • Adaption to sysfs rules.
    • Improve usability.
  • mon_statd:
    • Fix "Required Start/Stop" dependencies.
  • zfcpdump_v2:
    • With kernels 2.6.26, the port_add attribute was removed which caused "Dump to SCSI disk" to fail with the following message:
      ERROR: Could not open /sys/bus/ccw/drivers/zfcp/<bus_id>/port_add
      No such file or directory
                                                                  
      This has now been fixed.
  • zipl dump tools:
    • The tape dump tool provided incorrect input for the progress message.
      For memory sizes larger than 4G the progress message display stopped at 3584M thus leaving the user in doubt, whether the dump tool is still dumping or not.
      This has now been fixed.
