Impact on Legacy Systems
Legacy system users will see minimal impact in their applications or system
administration tools due to the changes in the platform infrastructure.
Although the configuration files on 64-bit systems (for example, /stand/system and
master.d/core-hpux) and SAM will refer to CB-CDIO, PSMs and new CDIOs now
included in the system, these components may coexist in the configuration files and be
loaded into the kernel at the same time, even if they are inactive on a particular
platform. Run-time checks evaluate which components are activated.
For legacy systems, end users might see new entries (sapic, lba, and sba) in the
/stand/system file. In addition, some new lines have been added to CDIO and
DRIVER_DEPENDENCY tables of the /usr/conf/master.d/core-hpux file to include the
new central bus (cb) and the various new PSMs (for example, pa_psm or
pa_generic_psm).
Configuration Changes
N4000 and rp7400 users must have the following modules in the kernel (via the master
file entries) for the PAT, SBA, and Lower Bus Adapter (LBA) components to be detected
and properly configured—and for the HP-UX kernel to boot. Without these modules, the
HP-UX kernel will be unable to detect the hardware CEC components on a N4000 pr
rp7400 system and the kernel will not boot.
The master file, /usr/conf/master.d/core-hpux, contains the following entries for all
systems.
$CDIO Table:
cb 1
lba 0
PCItoPCI 0
pa_generic_psm 0
