5 Administering HP APA

Administering HP APA consists of performing the following tasks:

“Modifying HP APA Global Parameters” (page 63)

“Logging Messages to the syslog.log File” (page 63)

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

For the September 2007 release of HP APA for HP-UX 11i v1 and

 

v2 this 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 (page 63) for

 

sample syslog.log messages and their meaning.

To change a global parameter, edit the /etc/rc.config.d/hp_apaconf and make the necessary changes. For more information, see “hp_apaconf File” (page 97).

Logging Messages to the syslog.log File

For the May 2005 release of HP APA for HP-UX 11i v1 (B.11.11.20) and later, the PHNE_33116 (B.11.11.17) release, and the December 2005 release for HP-UX 11i v2 (B.11.23.10), you can enable the logging of APA and LAN Monitor status messages to the syslog.log file. The status
