First-time Installation
For an initial HP APA installation, two files, hp_apaconf and hp_apaportconf are placed in
/etc/rc.config.d.
The default configuration port mode is MANUAL.
Configuration File Changes
This release enables the use of an optional HP_APA_LACP_TIMEOUT parameter in the
/etc/rc.config.d/hp_apaconf file. Valid values are 0 (slow) and 1 (fast). The default value
is 0.
Interoperability with HP Serviceguard
For this release of HP APA, to use link aggregates with HP Serviceguard, you must use HP
Serviceguard version A.11.17 or later. To use failover groups (LAN_MONITOR mode), you must
also install the HP Serviceguard PHSS_35427 patch. This patch also supports LACP link
aggregations and link aggregations with more than four ports.
For HP APA versions B.11.23.20 and earlier, you must install the HP APA PHNE_36403 patch to
use failover groups with HP Serviceguard version A.11.17.
