Team properties 141
• Every member of a CPQANS team must be connected to the same network segment. If you have
multiple CPQANS teams, each team must be on a separate network segment. If you are connected
to a VLAN-capable switch, each HP server adapter in a team must be connected to a port with the
same VLAN ID number (same network segment).
NOTE: VLAN is not supported on heterogeneous teaming.
• For mixed teams (different speed adapters), Network Fault Tolerance (NFT) is the only team mode
that allows for a team of different speed adapters. Such a team can contain any combination of HP
NC310x Gigabit Server Adapters, NC61xx Gigabit Server Adapters, NC71xx Gigabit Server
Adapters, NC31xx Fast Ethernet Server Adapters and so on. With a mixed team, you can designate
the highest-performance adapter as the preferred primary adapter. To set the preferred primary
adapter, use the "PRIMARY" keyword when binding CPQANS to the base driver for the Ethernet
server adapter.
Adapter performance hierarchy: Gigabit server adapter (1000 Mbps) is the fastest followed by the
Fast Ethernet (10/100 Mbps) server adapter.
Additional information
The following are some commands that can be helpful in configuring or troubleshooting teaming.
• CPQANS STATUS
o Description: This command displays the current status for the CPQANS team.
o Syntax: LOAD CPQANS STATUS
o Example: LOAD CPQANS STATUS
If you have more than one team, then you can issue the same command with the team's ID number.
o Syntax: LOAD CPQANS STATUS TEAM=<IDnumber>
o Example: LOAD CPQANS STATUS TEAM=2
• CPQANS PRIMARY
o Description: This command creates a preferred primary.
o Syntax: BIND CPQANS <adapter name> PRIMARY
o Example: BIND CPQANS N100_1_E82 PRIMARY
In this example, the adapter "N100_1_E82" is the preferred primary for the CPQANS team.
PRIMARY specifies which adapter in the team is the Preferred Primary adapter. If the Preferred
Primary adapter fails and is later replaced, or if a cable is reattached to fix a failure on the
primary adapter, the secondary adapter automatically passes control back to the Preferred
Primary.
For NFT mode teams, if you have a server with an HP Gigabit Server Adapter and an HP Fast
Ethernet Server Adapter, you would want the Gigabit Server Adapter to be the Preferred Primary. In
this scenario, if the Gigabit Server Adapter fails, the Fast Ethernet Server Adapter will take over.
Then, when the Gigabit Server Adapter is replaced, it will automatically revert to being the Primary
Adapter in the team.
NOTE: This command is only supported during the BIND command.
