Upgrading Backplanes from PCI to PCI-X

If you upgrade from the PCI to PCI-X backplane with the following server upgrades:

• rp7410 to rp7420

• the rp8400 to rp8420

• Superdome

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

1/0/8/0/0.6.0

the new hardware path is

1/0/8/1/0.6.0

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, please

see the LVM and vPars IO Backplane Upgrade document at:

http://docs.hp.com/hpux/11i/index.html#Virtual%20Partitions

Please 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.
