Notes That Apply To The Management Processor

Required Task: Change MP Settings on Console Switches

Perform this task before invoking the discover command.

In order for the discovery process to work correctly using the MP in DHCP mode, you must increase the amount of time the console switches hold MAC addresses. Increase this value from the default of 300 seconds to 1200 seconds. Make this change only on the console switches in the system, typically the ProCurve 26xx series.

From the ProCurve prompt, enter the configuration mode and set the mac-age-time parameter, as follows:

# config
(config)# mac-age-time 1200 

MP Disables DHCP Automatically

A known limitation exists with the MP firmware that causes the MP to disable DHCP automatically.

To work around this issue, the HP XC software performs the discovery phase with DHCP enabled. You must then perform a procedure to change the addresses on all MPs in the system to use the address received from DHCP as a static address.

For more information on how to perform this procedure, contact the HP XC Support Team at <xc_support@hp.com>.

Finding the IP Address of an MP

Because the IP addresses for the MPs are being set statically for this release, if a node must be replaced, you must set the IP address for the MP manually when the node is replaced.

To find the IP address, look up the entry for the MP in the /etc/dhcpd.conf file. The MP naming convention for the node is cp-node_name .
