RESOLUTION
HP Tru64 UNIX
Early Release Patches (ERPs) are now available
for all supported versions of HP Tru64 UNIX and
HP Trucluster Server. The ERP kits use dupatch to
install and will not install over any Customer Specific
Patches (CSPs) which have file intersections with the
ERPs. Contact your normal support channel and request
HP Tru64 services elevate a case to Support Engineering
if a CSP must be merged with one of the ERPs.
The following ERP kits are applicable to any system
running HP Tru64 UNIX and HP TruCluster Server software.
The ERPs are designed for clustered and non-clustered systems.
