a set of clients all at once. To set the same host tunings on all clients, specify the
clients
hostgroup.
CAUTION: Changing host tuning settings will alter file system performance. Contact HP Support
before changing host tuning settings.
Use the
ibrix_host_tune
command to list or change host tuning settings:
•
To list default values and valid ranges for all permitted host tunings:
<installdirectory>/bin/ibrix_host_tune -L
•
To tune host parameters on nodes or hostgroups:
<installdirectory>/bin/ibrix_host_tune -S {-h HOSTLIST|-g GROUPLIST} -o OPTIONLIST
Contact HP Support to obtain the values for
OPTIONLIST
. List the options as
option=value
pairs, separated by commas. To set host tunings on all clients, include the
-g clients
option.
•
To reset host parameters to their default values on nodes or hostgroups:
<installdirectory>/bin/ibrix_host_tune -U {-h HOSTLIST|-g GROUPLIST} [-n OPTIONS]
To reset all options on all file serving nodes, hostgroups, and X9000 clients, omit the
-h
HOSTLIST
and
-n OPTIONS
options. To reset host tunings on all clients, include the
-g
clients
option.
The values that are restored depend on the values specified for the
-h HOSTLIST
command:
◦
File serving nodes. The default file serving node host tunings are restored.
◦ X9000 clients. The host tunings that are in effect for the default
clients
hostgroup are
restored.
◦
Hostgroups. The host tunings that are in effect for the parent of the specified hostgroups
are restored.
•
To list host tuning settings on file serving nodes, X9000 clients, and hostgroups, use the
following command. Omit the
-h
argument to see tunings for all hosts. Omit the
-n
argument
to see all tunings.
<installdirectory>/bin/ibrix_host_tune -l [-h HOSTLIST] [-n OPTIONS]
•
To set the communications protocol on nodes and hostgroups, use the following command.
To set the protocol on all X9000 clients, include the
-g clients
option.
•
<installdirectory>/bin/ibrix_host_tune -p {UDP|TCP} {-h HOSTLIST| -g GROUPLIST}
•
To set server threads on file serving nodes, hostgroups, and X9000 clients:
<installdirectory>/bin/ibrix_host_tune -t THREADCOUNT {-h HOSTLIST| -g GROUPLIST}
•
To set admin threads on file serving nodes, hostgroups, and X9000 clients, use this command.
To set admin threads on all X9000 clients, include the
-g clients
option.
<installdirectory>/bin/ibrix_host_tune -a THREADCOUNT {-h HOSTLIST| -g GROUPLIST}

Linux clients. Use the
ibrix_lwhost
command to tune host parameters. For example, to set the
communications protocol:
<installdirectory>/bin/ibrix_lwhost --protocol -p {tcp|udp}
To list host tuning parameters that have been changed from their defaults:
<installdirectory>/bin/ibrix_lwhost --list
