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.
• Please 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” on page 107
• “rp8420 to rp8440 Hardware Path Changes” on page 107
• “HP 9000 Superdome Hardware Path Changes (x=cell)” on page 107.
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.
