Modifying HP APA Global Parameters

The following HP APA global parameters are stored in the /etc/rc.config.d/hp_apaconf file:

Default Port Mode

The default configuration mode for link aggregates. The supported values are as follows:

MANUAL: Disables FEC and IEEE 802.3ad LACP on all ports that support HP APA. You must manually add or remove them from the specific link aggregate. This is the default.
FEC_AUTO: Starts FEC on all ports that support HP APA.
LACP_AUTO: Starts IEEE 802.3ad LACP on all ports that support HP APA.
LAN_MONITOR: Disables FEC and IEEE 802.3ad LACP on all ports that support HP APA. The ports will be used for a failover group.

MAX Link Aggregates

Sets the maximum number of link aggregates for the server. The valid range is from 5 to 50, inclusive. The default value is 50. This value takes effect only after a reboot.

LACP SYSID Mode

LACP_AUTO only. Directs APA how to set up the LACP System ID. The supported values are as follows:

FIRST_APA_PORT: Sets the LACP System ID to the first supported HP APA port. This is the default.
FIRST_LACP_PORT: Sets the LACP System ID to the first active (UP) port that starts LACP.

LACP Timeout

Specifies an interval of time between LACP Protocol Data Units (PDUs) after which the server considers the LACP link partner to be down. The supported values are as follows:

0: Specifies a slow timeout. This is approximately 30 seconds. This is the default.
1: Specifies a fast timeout. This is approximately 3 seconds.

Use Syslog

Enables (1) or disables (0) the logging of status messages to the syslog.log file (for example, when a link aggregate or port fails or comes up). The default value is 0. See Section for sample syslog.log messages and their meaning.

To change a global parameter, do the following:

Click View/Modify APA Globals on the APA main page to display the View/Modify APA Globals page.
Select the global tunable you want to change. Repeat this step for each tunable.
Select Configuration Options.
Click OK to save the changes. An Operation Successful page appears, confirming the modification of the global parameters and the updating of the APA configuration.
Click OK. The APA main page displays.

By default, SMH changes the current APA configuration and saves the information and APA configuration to the /etc/rc.config.d/hp_apaconf, /etc/rc.config.d/hp_apaportconf, and /etc/lanmon/lanconfig.ascii files, which maintains the modified APA global parameter changes across reboots.
