Do the following:
• Verify that the switch is configured correctly with the appropriate
ports enabled. See the appropriate switch documentation to
determine if the switch ports connected to the server are
configured correctly for manual link aggregation (trunking) and
do not run FEC or LACP.
Verify that the link aggregate is configured by issuing the nwmgr
command. Link aggregate names begin with lan900 and have the
subsystem and interface type as hp_apa.
If the link aggregate is not configured, use the System Management
Homepage to configure it. See “Configuring a link aggregate” (page 34)
for more information.
Verify that the link aggregate is enabled by issuing the following
command:
# nwmgr -v -c lanxxx
where xxx is the link aggregate instance number (for example, 900).
If the aggregate is enabled, the APA State is Up.
If the APA State is Down, do the following:
1. Check the cabling between the NIC and the switch.
2. Verify that the link partner is configured to run manual trunks.
Make any changes, if necessary. Then, verify that the link aggregate
is enabled.
3. Verify that all ports in the aggregate are set to the same MANUAL
mode by using the following command:
# nwmgr -A all -c lanxxx
where xxx is the link aggregate interface name (for example,
lan900).
If they are not, use the System Management Homepage to modify
the link aggregate. See “Modifying a link aggregate” (page 39)
for more information.
