lib-zfcp-hbaapi

DESCRIPTION

This is lib-zfcp-hbaapi (zfcp HBA API library) Version 3.0.1. It is part of an implementation of FC-HBA for the ZFCP device driver.

The zfcp device driver is a FCP device driver for Linux on System z. The whole implementation of FC-HBA for the zfcp device driver is called zfcp HBA API. It is a shared library which provides the API defined in FC-HBA.

  • Version 3.0.1 contains small updates for building.
  • Version 3.0.0 re-licenses lib-zfcp-hbaapi to EPL-1.0.
  • Version 2.2.0 contains additional port speed capabilities.
  • Version 2.1.1 contains bugfixes and minor adaptations to build in recent Linux environments.
  • Version 2.1 extends version 2.0 with some additional features and two utilities (zfcp_ping, zfcp_show). These utilities are useful to discover a storage area network (SAN). Refer to the respective man-pages for further details.
  • Version 2.0 is a complete re-implementation.
  • Version 1.4 of lib-zfcp-hbaapi did not have a shared version of the library; libzfcphbaapi was linked statically against the san_disc tool. With Version 2, the shared version of the library is available again. The device file for the communication with the zfcp kernel module is not needed any more. The only interfaces utilized now are the sysfs and the generic scsi devices.

REQUIREMENTS

Software:

  • libsgutils
  • doxygen for developer documentation
  • Linux Kernel 2.6.27 (or later)
  • Linux kernel 2.6.36 (or later) required for event triggers.

Hardware:

  • The zfcp HBA API support was first available on IBM eServer zSeries 990 processors with a microcode level (MCL) that includes the enhancements of October 31, 2003. Please ensure to use the latest available microcode level.
  • All newer models are supported.

INSTALLATION

The package doxygen is required for the complete build of the sources.

Generic installation instructions are given in file INSTALL. To build and install lib-zfcp-hbaapi, use the following steps:

./configure
make
make docs
make install

Configuration options:

--enable-backtrace=yes|no    default: no
    Enable backtrace printing on mutex errors.

--enable-vendor-lib=yes|no    default: no
    Builds the library as a vendor specific library to be used with the
    common SNIA library (see http://hbaapi.sourceforge.net). All entry
    points will be in the common library (libHBAAPI.so) and the
    common library header file (hbaapi.h) needs to be used.
    If the common library is not available, libzfcphbaapi can be built
    standalone, enabling applications to directly link against
    libzfcphbaapi.so (--enable-vendor-lib=no)
    In that case, an own copy of hbaapi.h will be installed.

--enable-debug=yes|no        default: no
    Enable debug information.

--enable-docs=yes|no        default: yes
    Builds additional developer documentation and man pages via doxygen
    which will be installed as well.

lib-zfcp-hbaapi installs by default in /usr/local/lib. The HBA API header file is installed in /usr/local/include (only if compiled with --enable-vendor-lib=no, otherwise no header file will be installed) and documentation is installed in /usr/local/share/zfcp-hbaapi-3.x.

The library is named libzfcphbaapi.so. The HBA API header file is named hbaapi.h and should be included by applications that link against libzfcphbaapi.so. The header file will be supplied by the SNIA HBA API (see http://hbaapi.sourceforge.net) or by lib-zfcp-hbaapi, see paragraph above.

CLEANING UP

The following steps describe how to remove files that were generated during the build process.

make clean
    Deletes all object files an the doxygen documentation

make distclean
    Deletes all files generated during compilation

make maintainer-clean-local
    Deletes all files generated by the autotools. To generate them again,
    run "./bootstrap"
