If you upgrade from the PCI to PCI-X backplane
with the following server upgrades:
the hardware paths of the I/O devices will change.
The I/O device paths are in the format
cell/sba/lba/device/function.target.lun
When changing from the PCI to PCI-X backplane,
the device in the hardware paths
will change from 0 to 1. So, if a hardware path before the upgrade was
the new hardware path is
Not all I/O hardware paths change after the PCI
to PCI-X backplane upgrade. For details on the new paths for each
slot, see the respective hardware upgrade manuals available at http://docs.hp.com.
For vPars and other changes, including the correct
LVM and VxVM modifications on a vPars system, see the LVM
and vPars I/O Hardware Upgrade Process document at http://docs.hp.com/hpux/11i/index.html#Virtual%20Partitions.
Be aware that instead of performing the upgrades
for LVM, vPars, etc., you also have the option of performing a cold-install
on the upgraded rp8420 or rp7420 as if they were new systems with
no previous installations.
