6.2 Notes That Apply to Major Upgrades
The notes in this section apply to major upgrades.
6.2.1 Required Task: Add Missing MAC Addresses
Before you begin to upgrade the HP XC Version 2.1 system to this release, you must add missing
MAC addresses to the database for external devices on client nodes
Follow this procedure to populate the external device MAC address field in the database for
those client nodes with external connections. These MAC addresses are required by the upgrade
process to ensure that the external device information is populated correctly in the database and
that all external interfaces work properly after the upgrade.
1. Before turning off power to the client nodes in preparation for the upgrade, invoke the
ifconfig command on all nodes with external connections to capture the external device
MAC address.
# ifconfig | more
2. Write down the node name and its associated MAC address.
3. After you have upgraded the system, but just before invoking the cluster_config
--migrate | --init command, invoke the following device_config command to
set the external device MAC address in the database for a specific node. Run the
device_config command for every node with an external connection.
# cd /opt/hptc/config/sbin
# ./device_config --type E --host host_name MAC_address
4. Verify that the MAC addresses have been populated in the database:
# shownode config | grep -A 3 External:
6.2.2 Required Task: Determine MAC Addresses For Client Nodes With External
Devices
Before you upgrade the HP XC Version 2.1 system to this release, determine the MAC address
for client nodes with external devices. Later, you will add the MAC addresses to the database.
The first step is to determine the MAC address of the affected client nodes:
1. Before turning off power to the client nodes in preparation for the upgrade, invoke the
ifconfig command on all nodes with external connections to capture the external device
MAC address.
# ifconfig | more
2. Write down the node name and the MAC address associated with the external device. You
will use this address in “Required Task: Set External MAC Addresses Before Running the
cluster_config Utility” (page 51).
6.2.3 Required Task: Set External MAC Addresses Before Running the cluster_config
Utility
Perform this task after you have completed upgrade tasks up to including invoking the
upgradesys command, but just before invoking the cluster_config utility.
Follow this procedure to populate the external device MAC address field in the database for
client nodes with external connections. These MAC addresses are required by the upgrade process
to ensure that the external device information is populated correctly in the database and that all
external interfaces work properly after the upgrade.
