Tuning Nodes And Storeall Clients - HP StoreAll 8800 Administrator's Manual

a. Back up the current configuration:
mv /etc/ibrix/iadconf.xml /etc/ibrix/iadconf.xml.oldcp -p
/etc/ibrix/fusion.xml /etc/ibrix/fusion.xml.old
b. Create the new configuration file with the new cluster name:
/usr/local/ibrix/bin/register_server -p <Active FM VIF IP address>
-c <Cluster Node interface name, i.e. bon0> -n <Cluster Node
hostname> -H /usr/local/ibrix -a none -x
9. To verify that the configuration files have the new name, enter the following commands:
ibrix_fm_tune -l
grep -i clustername iadconf.xml
grep -i clustername fusion.xml
10. Repeat steps 8 and 9 on each node in the cluster.
1 1. To enable High Availability on the cluster nodes, enter the following command:
ibrix_server -m
12. To enable High Availability for the Fusion Manager, enter the following command on each
standby Fusion Manager node:
ibrix_fm -m passive
13. If you are using StoreAll clients in the cluster configuration, update the StoreAll client
configuration files:
a. Depending on your OS environment, copy or move the iadconf.xml file to another location
or rename the file.
b. Create the configuration file with the new cluster name:
register_client -p <Active FM VIF IP address> -c <local client
interface name> -n <IBRIX client hostname> -x
14. Verify that the iadconf.xml has been created and that the cluster name is correct.

Tuning nodes and StoreAll clients

Typically, HP Support sets the tuning parameters on the file serving nodes during the cluster
installation and changes should be needed only for special situations.
CAUTION:
environments. Because changing parameter values can alter file-system performance, HP
recommends that you exercise caution before implementing any changes, or do so only under the
guidance of HP technical support.
Host tuning changes are executed immediately for file serving nodes. For StoreAll clients, a tuning
intention is stored in the Fusion Manager. When StoreAll software services start on a client, the
client queries the Fusion Manager for the host tunings that it should use and then implements them.
If StoreAll software services are already running on a client, you can force the client to query the
Fusion Manager by executing ibrix_client or ibrix_lwhost --a on the client, or by
rebooting the client.
You can locally override host tunings that have been set on StoreAll Linux clients by executing the
ibrix_lwhost command.
Tuning nodes
The Modify Server(s) Wizard can be used to tune one or more servers in the cluster. To open the
wizard, select Servers from the Navigator and then click Tuning Options from the Summary panel.

The default values for the host tuning parameters are suitable for most cluster
