HP has developed a new script which simplifies the process of
installation of multiple patches. This script can be used at the
customer site to install multiple patches thereby saving the
overhead of waiting for the engineering to provide them with the
Currently, users can install only one patch in a single run of dupatch. So,
if a user has to install 'n' patches, then dupatch needs to be run 'n' times and
requires machine reboot several times. In case of a cluster, when the number of
patches to be installed in a no-roll method is more, then, even no-roll method
will approach the complexity and time of a rolling upgrade, and the advantage of
a no-roll is lost.
HP is releasing the below ERP kit publicly for use by any customer. This ERP
kit delivers a new script, using which the existing “dupatch” script will be
able to install multiple CSPs/ERPs in a single operation without multiple
reboots on both stand-alone and cluster systems. The script will be
delivered along with the patch installation tools as an ERP for HP Tru64
UNIX 5.1B-6. The instructions regarding the usage of this script, "mul_patch_setup"
are available at the location of the downloadable file.
Please note that this script will not be made available in any base level
