HP-UX Virtual Partitions Administrator Guide - Hewlett Packard

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, 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.
Updates Involving VPARSBASE
VPARSBASE (the free demo product for HP-UX 11i v1) is no longer available or supported.
You can update directly only from free product to newer free product or from purchased product
to newer purchased product. You cannot update directly from free product to the purchased
product.
If you wish to update from the free product to the purchased product, first you need to remove
the free product VPARSBASE, and then install the purchased product T1335AC for HP-UX 11i
v1.
To avoid having to recreate your vPars configuration, you can perform the following steps:
1. Backup the file /stand/vpdb (this file is the vPars partition database)
2. Remove the free product from all virtual partitions. See “Removing the vPars Product”
(page 123).
3. Install the full product. See “Installing vPars with Ignite-UX on PA-RISC” (page 118) or
“Installing vPars with Software Distributor ” (page 122).
However, while in standalone mode, at the point where you would normally create the
virtual partitions using vparcreate, restore /stand/vpdb.
Then continue with the installation as you normally would.
Installing vPars with Ignite-UX on PA-RISC
1. Boot your system using the Ignite-UX server. If your Ignite server’s IP address is
