HP nPartitions (nPars) manual Pre-Upgrade Procedure for PI, Post-Upgrade Procedure for PI

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: swlistgrep HPPortableImage

b.If nothing is returned, then the package must be installed now. Go to www.software.hp.com and search for “HP 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

5.Dump the saved PI state to a text file for possible use later. Obtain the dump by executing the following command:

/opt/network/bin/hpuxpitool –g

This will list out each network instance along with its pre-upgrade MAC address.

6.Shutdown the OS using a shutdown command.

Post-Upgrade Procedure for PI

1.Dump the new PI state to a file for possible use later. Obtain the dump by executing the following command:

/opt/network/bin/hpuxpitool –g

This will list out each network instance along with its post-upgrade MAC address.

2.Disable PI by executing the following command:

/opt/network/bin/hpuxpitool -d

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.
