Configuring an IP Address
After you configure HP APA, you must configure an IP address on the interface. To configure an IP address for a link aggregate, use the following command:
#ifconfig lanxxx IP_address up
Where xxx is the link aggregate PPA number.
To make this change permament, edit the /etc/rc.config.d/netconf file and include the appropriate entry. For more information, see ifconfig(1M).
For failover groups, you must configure an IP address on the interface that is to be the primary link before running the lanqueryconf and lanapplyconf commands to configure the failover group. For more information, see “Editing Configuration Files for Failover Groups” (page 107).
Configuring the Link Partner
HP APA also requires that you configure your switches' trunking mode (AUTO or MANUAL) to match the mode being used on the server (for example, Cisco Fast EtherChannel (FEC), IEEE 802.3ad Link Aggregation Control Protocol (LACP), or MANUAL).
If you selected HOT_STANDBY as the load distribution algorithm for a MANUAL mode link aggregate or configured a failover group, do not configure the switch ports for an aggregation. See Appendix E (page 119) for additional switch information.
Configuring HP Serviceguard
HP recommends that you configure HP Serviceguard after configuring HP APA. You can then use the link aggregates or failover groups in your HP Serviceguard configuration. See the HP Serviceguard documentation for more information.
NOTE: Do not configure HP Serviceguard with ports that are part of a link aggregate or failover group.
Creating VLANs Over APA
To create VLANs over link aggregates or failover groups, complete the following steps:
1.Decide what ports are to be part of the link aggregate or failover group. Then, decide on the VLANs that will be created over the link aggregate or failover group.
2.Configure the trunks and VLANs on the switch according to the switch’s documentation. If you want to enable a VLAN on a link aggregate, its trunk on the switch side must be tagged with the VLAN’s ID.
If you want to enable a VLAN on a failover group, the member ports of the failover group on the switch side must be tagged with the VLAN’s ID.
3.On the server side, create the link aggregates or failover groups. Then, create the VLANs over the link aggregate or failover group.
After a link aggregate is in use, you can create, modify, and delete VLANs over it. Users can leave behind VLANs after the link aggregate or failover group has been cleared. If the link aggregate or failover group has been cleared, users can neither create VLANs nor modify any VLANs on the link aggregate or failover group. Users can only delete the VLANs.
See Appendix D (page 113) for examples of configuring VLANs over APA using HP Procurve switches.
Verifying the Configuration
HP APA configuration is complete when you can verify that a link aggregate has been formed. To verify the HP APA configuration, complete the following steps:
