ibrix_lwhost

Tunes Linux X9000 clients. This command can be run on X9000 clients only.

Description

Use ibrix_lwhost to set Linux X9000 client parameters:

• Server settings

• Preferred network interface for communication with a file serving node

• Communications protocol

• Number of server threads

Changes take effect immediately and are persistent. This command also initiates a management

console query that allows the X9000 client to pick up new host tunings.

Use ibrix_lwhost --list to list local server settings that have been changed. The output does

not list default settings that are still in effect.

CAUTION: Changing tuning parameters will alter file-system performance. Contact HP technical

support before changing any tuning parameters.

Synopsis

Tune server settings:

ibrix_lwhost --tune -p param -v value

Contact HP technical support for information about the values to use for param and value.

Prefer a network interface for communicating with a file serving node:

ibrix_lwhost --nic -h host -n server_ifname

Specify a communications protocol:

ibrix_lwhost --protocol -p {tcp|udp}

The default protocol is UDP.

Set the number of server threads:

ibrix_lwhost --threads -v value

Initiate a management console query to allow the X9000 client to pick up new host tunings:

ibrix_lwhost --a

For example, you could use this option if file allocation policies have been changed since the

X9000 client started and you want the X9000 client to acquire the new settings immediately.

List X9000 client parameters that have been changed from their defaults:

ibrix_lwhost --list
