Installing and configuring Red Hat Enterprise Linux and SUSE Linux Enterprise Server 9 SP3 client systems3–16

TIP: Alternatively, you can use the ib-setup tool to configure this setting on each client node.

11. This step applies only if a Voltaire InfiniBand Version 3.4.5 interconnect driver is used.

You must change the ARP resolution parameter on each of the client nodes. By default, this parameter

is set to Dynamic Path Query; you must now update it to Static Path Query (unless there is

a specific reason why it needs to be set to Dynamic Path Query).

To update the ARP resolution parameter, perform the following steps on each client node where a

Voltaire InfiniBand Version 3.4.5 interconnect driver is used:

a. Stop the Voltaire InfiniBand interconnect software by entering the following command:

# service voltaireibhost stop

CAUTION: You must stop the interconnect software before you proceed to Step b. If you do not,

the parameter that you change in Step b will be reset to the default the next time the client node

is rebooted.

b. In the /usr/voltaire/config/repository.rps file, replace the following value:

"sa-queries"=0x00000001

with this value:

"sa-queries"=0x00000000

c. Restart the Voltaire InfiniBand interconnect software by entering the following command:

# service voltaireibhost start

TIP: Alternatively, you can use the ib-setup tool to configure this setting on each client node.

12. When you have installed the client kernel, there should be an initrd file (/boot/initrd-

kernel_version.img) on the client node; however, if the modprobe.conf or modules.conf

file on the client node is not suitable for the client kernel supplied with the HP SFS client software, the

initrd file will not be created.

If the initrd file does not exist after you have installed the client kernel, you must modify the

modprobe.conf or modules.conf file, and then create the initrd file manually (see

Section 7.1.1 for instructions). When you have finished creating the initrd file, you can safely

return the modules.conf file to its previous state.

When you have finished installing the HP SFS client software, proceed to Section 3.3.3 to run the

sfsconfig command on the client node.

3.3.3 Step 3: Running the sfsconfig command after installing the software

When you have finished installing the HP SFS Version 2.2 client software on the client node, you must

configure the options lnet settings and the lquota settings on the client node. You can use the

sfsconfig command to configure these settings automatically.

Run the sfsconfig command by entering the following command, where server_name is the name of

an HP SFS system that the client node will access:

# sfsconfig --server server_name[--server server_name] [--server server_name --server

server_name...] all

The sfsconfig command creates a new /etc/modprobe.conf.lustre or

/etc/modules.conf.lustre file (depending on the kernel distribution of the client) that contains the

appropriate settings, and includes the new file in the /etc/modprobe.conf or /etc/modules.conf

file.
