Environment
Novell Access Manager 3.1 Linux Access Gateway (LAG)
Novell Access Manager 3.1 SUpport PAck 3 applied
SLES 11 based LAG
Novell Access Manager 3.1 SUpport PAck 3 applied
SLES 11 based LAG
Situation
LAG configured to accelerate multiple protected back end Web applications on a new install of Access Manager. When exchanging larger files, noticeable delays are experienced by the users. Switches are hard coded for full duplex 100MB. The NIC configuration was done using yast and not iManager, and worked fine. When a change was applied through iManager, performance issues were seen. It appears as though changes are not reflected in interface related configuration files when we push
them through iManager.
Resolution
Modify the postapply.sh file (/chroot/lag/opt/novell/bin/ dir) to include the ethtool statement eg.
/sbin/ethtool -s eth3 duplex full speed 100 autoneg off
The full path to ethtool (/sbin/ethtool) must be specified else the command will not be found. This sync'd up the LAG and switch settings and performance went back to normal.
/sbin/ethtool -s eth3 duplex full speed 100 autoneg off
The full path to ethtool (/sbin/ethtool) must be specified else the command will not be found. This sync'd up the LAG and switch settings and performance went back to normal.
