Determine whether the SizingActions script should be
used
HP Scalable NAS includes a script called SizingActions that configures certain
operating system parameters to improve system performance, particularly in a file
serving environment. The changes improve network throughput and make better use
system memory. On HP X5500 Storage Gateway for Linux servers and HP 4400
Scalable NAS File Services systems, additional changes are made to tune the
operating system for the hardware provided with those systems.
The SizingActions script is run when HP Scalable NAS starts up. The script does
not determine whether the system parameters it adjusts have been modified from
their default values by a user on the system. This can be an issue if, for example, you
are running an application that requires system parameters such as vmem_max or
mmem_max to be modified, typically in the /etc/sysctl.conf file.
If you do adjust system parameters to support external applications such as Oracle,
you should disable the SizingActions script as described below. Because disabling
the script will typically result in a degradation to network file serving performance,
HP recommends that you do this only if you must adjust parameters for best
performance for your application. HP does not recommend manually editing the
SizingActions script, as it may be replaced during an upgrade or hotfix and
those changes will not be preserved during the upgrade process.
To disable the SizingActions script, execute the following steps on each server
in the cluster:
1. Go to the directory containing the SizingActions script:
# cd /etc/opt/hpcfs
2. Run the following command:
# chmod 444 SizingActions
