6.3.8.1. Install HPSS 6.2 Distribution Image
This step can be performed while the HPSS 4.5 or 5.1 system is running.
Prior to installing the HPSS 6.2 code, sites should not disturb the current HPSS release code. It is
possible for a site to revert to the previous release of HPSS at any point prior to the last step of
starting the HPSS 6.2 servers. In order to facilitate reverting to the previous release of HPSS, sites are
recommended to install the HPSS 6.2 code in a separate file system from the previous release of
HPSS code and set up BUILD_TOP_ROOT as a symbolic link. For example, if HPSS 4.5 or 5.1 code
is installed in /opt/hpss, a site could install HPSS 6.2 in /opt/hpss62 and make /opt/hpss as the
symbolic link pointing to the version of HPSS they desire to run. To proceed with this conversion,
BUILD_TOP_ROOT should point the symbolic link, and the symbolic link should point to the HPSS
6.2 code.
6.3.8.2. Compile HPSS 6.2 Source Code (if necessary)
This section applies to sites that are upgrading from both HPSS 4.5 and HPSS 5.1. Install the HPSS
6.2 distribution images. Edit Makefile.macros and the Makefile.macros.* for the specific platform
being used (e.g. Makefile.macros.AIX).
Constants that normally need modification in Makefile.macros include:
•
BUILD_PLATFORM
•
BUILD_TOP_ROOT
•
BUILD_UNSUPPORTED
•
CONVERSION_SUPPORT
•
CONVERSION_FROM_51
•
CONVERSION_FROM_45
•
MVR options (MVR1_OPTION)
Note that BUILD_TOP_ROOT should point to the HPSS 6.2 code. CONVERSION_SUPPORT
should be set to on and either CONVERSION_FROM_51 or CONVERSION_FROM_45 should be
on depending on the version of HPSS a site is upgrading from. If CONVERSION_FROM_45 is on,
the site must have Encina SFS installed and should ensure that the ENCINA constant in
Makefile.macros is correct.
Constants normally needing modification in Makefile.macros.AIX include:
•
DB_INSTALL_PATH
•
LDAP_INSTALL_PATH – only if using LDAP authorization
•
KRB5PATH – only if using Kerberos authentication
•
STK_INCLUDE
•
STK_LIB
•
PVR_LIST
After updating Makefile.macros and the platform specific Makefile.macros, compile the HPSS 6.2
