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}
Tuning X9000 clients locally
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
See the
ibrix_lwhost
command description in the HP StorageWorks X9000 File Serving
Software CLI Reference Guide for other available options.
Windows clients.
Click the
Tune Host
tab on the Windows X9000 client GUI. Tunable parameters
include the NIC to prefer (the default is the cluster interface), the communications protocol (UDP
or TCP), and the number of server threads to use. See the online help for the client if necessary.
Migrating segments
To improve cluster performance, segment ownership can be transferred from one host to another
through segment migration. Segment migration transfers segment ownership but it does not move
segments from their physical locations in networked storage systems. Segment ownership is recorded
on the physical segment itself, and the ownership data is part of the metadata that the management
console distributes to file serving nodes and X9000 clients so that they can locate segments.
