3.7.0 HP StorageWorks HP Scalable NAS File Serving Software installation guide HP Scalable NAS for Linux (AG513-96004, October 2009)

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
3. Reboot the node to ensure that the SizingActions parameters are cleared
from the system. The SizingActions script will now be inactive at system
start.
Install the Management Console on other hosts
For best performance, the cluster should be monitored from a separate administrative
station rather than from a server in the cluster. The Management Console software
can be installed on either Linux or Microsoft Windows systems.

Systems used for the Management Console must meet these requirements:
