If UNIX authorization will be used, this product is not required. LDAP authorizati on is
supported on AIX only.
If LDAP will be used for HPSS authorization, download the IBM Tivoli Directory Server from
http://www.ibm.com. Search for "IBM Tivoli Directory Server" on the site to find the download
page. The download page presents many options for downloading the software. Download version
6.0 of the package that is a tar file containing the LDAP software and its prerequis ites. Find a
temporary directory with plenty of space and extract the tar file. There will be a script named "setup"
in the root directory where the tar file was extracted. Run this script to start an installation wizard to
install the software. When the installation program offers to install DB2, do not install it as it is a
trial version. LDAP will use the version of DB2 that is installed from the HPSS install ation CD.
Installing the IBM Kerberos client is required only if LDAP is being used for authorization and you
will be using Kerberos authentication with the LDAP daemon. The fileset for the IBM Kerberos
client is located on the AIX 5.2 Expansion Pack CD #2. Use the normal AIX software installation
programs (e.g. installp or smit) to install the krb5.client.rte fileset from that CD. If you will be using
Kerberos authentication with LDAP, the LIBPATH environment variable must be set to include /usr/
krb5/lib. Since this is required for all clients and servers, this shoul d be set in /etc/environment.
Because HPSS requires the use of MIT Kerberos , the LIBPATH must also contain the path to the lib
directory of the MIT Kerberos installation. For example, if /etc/environment alre ady contains a
setting "LIBPATH=/usr/lib", and MIT Kerberos is installed under /usr/local, the setting in the file
/etc/environment should be changed to "LIBPATH=/usr/lib:/usr/local/lib:/usr/krb5/ lib".
If planning to use the LDAP option, the default binaries are not enabled to c ommunicate
with the LDAP system. HPSS must be recompiled/relinked. The HPSS source
images/packages must be installed and the Makefile.macros file updated to “turn on”
LDAP. Look for the line with LDAP_AUTH_SUPPORT, and change the “off” to “on”.
Rebuild HPSS according to the instructions in Section 5.8.1.2: Build the HPSS Base Source Tree on
page 172.
5.2.4. Install Prerequisi te Software for XFS HDM
XFS is not supported in HPSS 6.2. XFS references have been left in the HPSS
documentation to support the option of re-enabling XFS in future releases.
The XFS HDM is available only on Linux. Unlike the other components of HPSS which run under
the Redhat Linux distribution, the XFS HDM requires the SUSE Linux distributi on. This is because
Redhat kernels do not have support for the Data Management Application Programming Interface
(DMAPI) . DMAPI is required to link an XFS filesystem to HPSS.
To prepare a machine to run the HPSS HDM:
•Install SUSE LINUX Enterprise Server (SLES) version 9 Service Pack 2 or greater. See
http://www.suse.com for details.
•Install MIT Kerberos 1.3.5
•Use yast to install the following XFS and DMAPI userspace programs:
·dmapi-2.2.1-0.2 or higher
·xfsdump-2.2.25-0.2 or higher
·xfsprogs-2.6.25-0.2 or higher
