Table 1 Fixes in the HP APA B.11.11.30 Release (continued) Defect ID Description CR: JAGaf69619 SR: 8606409736 Under some stress situations (for example, a port is continuously enabled and then disabled to run LACP), the system panics with data page fault in the lacp_notify_msg function. CR: JAGaf69665 SR: 8606409782 When a user application sends a DL_HP_HW_RESET_REQ primitive to a link aggregate or failover group, APA returns the error code 233 (EOPNOTSUPP).
Table 1 Fixes in the HP APA B.11.11.30 Release (continued) Defect ID Description CR: JAGag17374 SR: 8606461410 The lanqueryconf command might put ports having VLANs configured on them into failover groups. The lanapplyconf command fails if it detects these ports inside a failover group. CR: JAGag17375 SR: 8606461411 The lanapplyconf command cannot create failover groups whose member ports have an MTU of 259 or less.

2 HP APA Overview for HP-UX 11i v2 This chapter provides information about the HP-UX 11i v2 (B.11.23.40) December 2007 release of HP Auto Port Aggregation (APA) and LAN Monitor software. This release of HP APA now supports HP Serviceguard version A.11.17 or later. HP Serviceguard can use both link aggregates and failover groups (LAN_MONITOR mode). In addition, this release also supports Nortel Split Multi-Link Trunking (SMLT) technology and improved HP Integrity virtual machine support.
Known Problems and Limitations This section describes the known problems and limitations as known to HP at time of publication. If workarounds are available, they are included. Known Problems • 3Com SuperStack II Switches To interoperate with the switch, disable the Trunk Control Message Protocol (TCMP) on all of the ports that are being used with HP Integrity servers.
• HP ProCurve • Foundry • Alteon • Nortel • Extreme HP APA also supports Nortel's Split Multi-Link Trunking (SMLT) technology. Specifically, HP has tested the Passport 8006 and Passport 8010 switches with the version 3.7.13.0 of the software. NOTE: Hot Standby and LAN Monitor modes are both supported with all switches; however, HP strongly recommends using LAN Monitor rather than Hot Standby mode.
Other Requirements • HP APA must be installed with the system up. • A reboot will be required. • Installation requires superuser permissions. • Estimated time to install the software is 3 to 5 minutes, depending on the complexity of your system. Related Information The latest documentation for HP APA is available in at www.hp.com/go/hpux-APA-docs.
3 HP APA Overview for HP-UX 11i v3 This chapter provides information about the HP-UX 11i v3 (B.11.31.50) March 2011 release of HP Auto Port Aggregation (APA) and LAN Monitor software. This release of HP APA is a defect fix only release; there are no new features. Auto Port Aggregation HP APA is a software product that creates link aggregates, often called "trunks," which provide a logical grouping of two or more physical ports into a single "Fat-Pipe.
Corrective Action: To use the network physical port on the HP 9000 server, physically move the connection from the server to the switch to another non-Cisco Fast EtherChannel port on the switch. • Cisco Catalyst 5000 Switches Turning off Cisco's Fast Ether Channel protocol on one network physical port on the HP 9000 server might cause the entire link aggregate (the port it is associated with) to be deconfigured.
NOTE: HOT_STANDBY and LAN_MONITOR modes are both supported with all switches; however, HP strongly recommends using LAN_MONITOR mode. The following network adapter cards are supported: • All HP PCI 10/100Base cards (both FX and TX) • All HP PCI 1000Base cards (both Base-T and SX) • All HP PCI-X 2-port Combination cards (network ports only) • PCI-X 10 GbE Fiber cards (failover groups only) Required Disk Space Approximately 2 MB.
