Tuning file serving nodes from the CLI
All Fusion Manager commands for tuning hosts include the
-h HOSTLIST
option, which supplies
one or more hostgroups. Setting host tunings on a hostgroup is a convenient way to tune 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 alters 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:
ibrix_host_tune -L
•
To tune host parameters on nodes or hostgroups:
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:
ibrix_host_tune -U {-h HOSTLIST|-g GROUPLIST} [-n OPTIONS]
To reset all options on all file serving nodes, hostgroups, and StoreAll 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.
◦
StoreAll 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.
