•The disk, where the installation target directory resides, has enough space t o hold all the
HPSS packages to be installed on this node.
•WARNING: Do not use NFS mounted directories for installing nor allocating space for HPSS
related components. Installing on NFS is problematic and the errors can be difficult to
diagnose.
5.2. Install Prerequisi te Software
This section provides an overview of how to install the prerequisite software to prepare for the
upcoming HPSS configuration. Verify that the correct software versions are obtained as described in
Section 3.3.1: Prerequisite Software Overview on page 58.
5.2.1. Install Java
Java is required to compile HPSS software. It is also required to run the SSM Graphical User
Interface (hpssgui), the SSM Command Line Interface (hpssadm) and the mkhpss tool. If the site
needs to compile the HPSS code, the Java Software Development Kit (SDK) must be installed. To
run HPSS applications, either the Java SDK or the Java Runtime Environment (JRE) is re quired.
It is recommended that the Java SDK component be installed on the machines where HPSS code is to
be compiled and on the machine where mkhpss will be running. Also, the JRE component should be
installed on each SSM client machine. This is to enable the hpssgui appli cation to run directly on the
client machine to maximize hpssgui performance and to eliminate the X traffic on the HPSS server
machine.
See Section 3.3.1.4: Java on page 59 to obtain the download website. Follow the install ation
instructions provided on the website to install Java. Be sure that all Java's prerequisite requirements
are met before installing the product.
5.2.2. Install MIT Ker beros (If Using Kerberos Authentication)
The capability to use MIT Kerberos authentication is provided in HPSS 6.2, howeve r, IBM
Service Agreements for HPSS do not provide support for defects in MIT Kerberos. Kerberos
maintenance/support must be site-provided.
For Linux, Kerberos is included in the Operating System and does not need to be installe d.
For AIX, download the Kerberos 1.4.2 source from http://web.mit.edu/kerberos. Extract the s ource
tree into the desired location; the recommended location is /usr/local. Under the newly extracted tree
go to krb5-1.4.2/source. Execute the following commands:
> configure --enable-shared
> make
> make install
MIT Kerberos will be installed in the configured directory.
5.2.3. Install LDAP ( If Using LDAP Authorizatio n)
LDAP authorization is not supported by IBM Service Agreements. The following inf ormation
is provided for sites planning to use LDAP authorization with HPSS 6.2 as a site supported
feature.
