hba.conf - configuration file for the HBAAPI library


The /etc/hba.conf file is used to specify the Vendor-Specific Libraries that are installed on the system. This file is used by the Common Library to load the individual VSLs when HBA_LoadLibrary(3HBAAPI) is called. If changes are made to the file while the library is in use, the library should be freed and reloaded. A version 1 VSL is compatible only with a version 1 Common Library. A version 2 VSL is compatible with both a version 1 and a version 2 Common Library.

Each VSL entry is a single line of the form:

"name"	    "library path"



is the description of library. The library name should be prepended with the domain of the manufacturer of the library.

library path

is the absolute path to the shared object library file.


Example 1 Contents of /etc/hba.conf
# This file contains names and references to HBA libraries
# Format:
# <library name>  <library pathname>
# The library name should be prepended with the domain of
# the manufacturer or driver author.
com.sun.fchba32		/usr/lib/libsun_fc.so.1
com.sun.fchba64		/usr/lib/sparcv9/libsun_fc.so.1

The HBAAPI is provided in both 32– and 64–bit versions, but only one configuration file is specified. As a result, both 32– and 64–bit VSL libraries must be specified within the same file. When using the 32–bit Common Library, the 64–bit VSLs will fail to load. When using the 64–bit Common Library, the 32–bit VSLs will fail to load. These failures are silently ignored by the Common Library during normal usage, but can result in warning messages when running client applications in a debugger.
