Conﬁguring HP LocalDirector Controller

Problems With HP LocalDirector Controller and

Cisco LocalDirector

1. To verify that the HP LDC agent (ldc_agt) is up and running, type

the following:

ps -efa|grep ldc_agt

If ldc_agt is not running, start ldc_agt to see if it solves the

problem. Refer to “Starting and Stopping the HP LDControl Daemon”

on page 68.

If ldc_agt stops running a few minutes after you have started it,

dynamic weighting may be turned off (see Step 3b).

2. Look at the log ﬁle /var/opt/hpldc/ldc.log for error messages

that may indicate the problem.

3. Look at the entries in /etc/opt/hpldc/conf/ldc.conf for the

following:

a. Make sure the value of LDHostname is conﬁgured to the name of

the Cisco LocalDirector. Use ping to test the network

connectivity to the Cisco LocalDirector:

ping <LD_hostname>

where <LD_hostname> is the value of LDHostname.

b. Look at the value of DynamicWeight.

If DynamicWeight is set to “off,” the HP LDC agent sends the

Initial weight to Cisco LocalDirector and then stops running, since

there are no on-going dynamic weight adjustments. In the ‘off”

mode, it is normal for the HP LDC agent to stop running a few

minutes after it has been started.

If DynamicWeight is set to “on,” the HP LDC agent sends the

Initial weight to Cisco LocalDirector and then continues to run so

it can monitor the system and dynamically change the weight if

needed. In the “on” mode, the HP LDC agent should always be

running.

c. Verify the value of InitialWeight. Compare the value of

InitialWeight in ldc.conf with the number stored in

/var/opt/hpldc/weight. They should be identical.

• If they match, you are ready to run the snmp_test program.
