NOTE:
While the network mapping has been adjusted to preserve the original mapping of networks to
ports, it is not possible to adjust the MAC address assignment to preserve the same mapping of
MAC addresses to ports. If your OS is HP-UX, see the section Preserving VC-assigned MAC
addresses in HP-UX by enabling Portable Image on page 82 for a method which can be used
to preserve VC-assigned MAC addresses.

Preserving VC-assigned MAC addresses in HP-UX by enabling Portable Image

If your OS is HP-UX where the VC server profile does not use the hardware default MAC addresses and it
is important that Ethernet connections configured in the OS retain their VC-assigned MAC addresses,
then there is a package called "Portable Image" (PI) which can be used. The HP-UX Portable Image
product is installed and enabled on the blade server before the upgrade. After the upgrade, PI will
automatically modify the HP-UX network instance numbers of the new hardware environment so that they
match the pre-upgrade environment. This takes advantage of the VCM interconnect stacking links to
allow all of the Monarch Server network connections to function correctly with no corrections needed in
the original VC server profile.
If you choose to use PI to assist the upgrade, there will be a pre-upgrade step to follow on the designated
Monarch Server and then another step to follow after the upgrade. These two steps are detailed below
but they must not be executed until they're explicitly called for in the upgrade procedure steps.
Pre-Upgrade Procedure for PI
These instructions are to be executed on the designated Monarch Server with the OS booted.
1. You need to obtain the PI package if it's not already installed.
a. Check for it being already installed by executing the following command:
swlist|grep HPPortableImage
b. If nothing is returned, then the package must be installed now. Go to http://www.hpe.com/
support/softwaredepot and search for "Portable Image". Follow the link for HP-UX Portable
Image in the product list and follow the instructions there for installing the depot.
2. Clear out any old PI data by executing the following command: /opt/network/bin/hpuxpitool -
r all
3. Enable PI by executing the following command: /opt/network/bin/hpuxpitool -e
You should see the following:
* Future operations will ask whether to update the backup.
* The requested changes have been applied to the currently
running configuration.

4. The PI state must be saved before starting the upgrade. This is done by explicitly executing the PI
save command:
/opt/network/bin/hpuxpitool -s
