HP-UX Virtual Partitions Administrator's Guide (includes A.03.05 and A.04.05)

Upgrading HP 9000 Servers from the sx1000 to sx2000 Chipset
You can upgrade the following HP 9000 servers from the sx1000 to sx2000 chipsets:
• rp7420 to rp7440
• rp8420 to rp8440
• HP 9000 Superdome
To perform the hardware upgrade, follow the process documented in the hardware upgrade
manual for your server.
CAUTION:
Upgrade Notes
• vPars A.03.04 is required for vPars running on HP 9000 servers with the sx2000 chipset.
• The physical hardware upgrade from the rp7420 to rp7440 requires a cold-install of the OS
and therefore of vPars as well.
• Only Hewlett-Packard qualified service personnel can perform hardware upgrades from
rp8420 to rp8440 or from HP 9000/sx1000 Superdome to HP 9000/sx2000 Superdome.
While performing the hardware upgrades, HP qualified service personnel will reference the
following documents when making the necessary HP-UX and vPars configuration changes:
HP I/O Hardware Upgrade Script Guide for HP 9000/sx2000 Superdome Servers and HP-UX
Impacts on the Upgrade Process for the rp8420 to rp8440 Hardware Upgrade.
• Be aware that instead of performing the upgrades for vPars, LVM, etc., you also have the
option of performing a cold-install on the post-upgrade hardware as if they were new systems
with no previous installations.
Hardware Path Changes
The upgrade changes the hardware paths. For the new hardware paths as well as the hardware
upgrade process, see the upgrade manual for your server. For reference, the changes are noted
in the tables at the end of this section:
• “rp7420 to rp7440 Hardware Path Changes ” (page 109)
• “rp8420 to rp8440 Hardware Path Changes ” (page 110)
• “HP 9000 Superdome Hardware Path Changes (x=cell)” (page 110).
vPars Database Changes
As part of the upgrade process, HP qualified service personnel will need to make updates to
each virtual partition’s vPars database (vpdb) in standalone mode to reflect the new server
hardware. These and other necessary steps are described in the HP I/O Hardware Upgrade Script
Guide for HP 9000/sx2000 Superdome Servers and HP-UX Impacts on the Upgrade Process for the
rp8420 to rp8440 Hardware Upgrade service documents.
Hardware Path Tables
The following tables show the new hardware paths. For details on the new hardware paths and
other hardware information, see the applicable hardware upgrade manuals for your server,
available at http://docs.hp.com.
