6.3 HP StoreAll 9300/9320 Storage Administrator Guide (AW549-96072, June 2013)

Tuning file serving nodes from the CLI
All Fusion Manager commands for tuning hosts include the -h HOSTLIST option, which supplies
one or more host groups. Setting host tunings on a host group 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 host group.
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 host groups:
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 host groups:
ibrix_host_tune -U {-h HOSTLIST|-g GROUPLIST} [-n OPTIONS]
To reset all options on all file serving nodes, host groups, and StoreAll clients, omit the -h
HOSTLIST and -n OPTIONS options. To reset host tunings on all clients, include the -g
clients option.
