Installing the HP SFS client software on HP XC systems (new installations) 2–3

3. The binary distribution directory contains a number of subdirectories, with one subdirectory for each

architecture. Within each subdirectory, there is an XC directory containing binary RPM files. Identify

the correct directory for the architecture on your client node, then change to that directory, as shown

in the following example.

In this example, the architecture is ia64 and the HP XC software version is 3.0:

# cd ia64/XC_3.0/

The directories each contain a number of packages, as follows:

• lustre-modules

• lustre

• hpls-lustre-client

• python-ldap (for ia64 systems only)

• hpls-diags-client

The first four of these packages are mandatory and must be installed. The hpls-diags-client

package provides SFS client diagnostic utilities and is optional.

4. Install the packages, as shown in the following example. In this example, the optional

hpls-diags-client package is installed. You must install the packages in the order shown here:

# rpm -ivh lustre-modules-version_number.rpm \

lustre-version_number.rpm \

python-ldap-version_number.rpm \

hpls-lustre-client-version_number.rpm \

hpls-diags-client-version_number.rpm

When you have finished installing the HP SFS client software on the head node, proceed to Section 2.2.2

to run the sfsconfig command on the node.

2.2.2 Step 2: Running the sfsconfig command after installing the client software

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

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

sfsconfig(8) command to configure these settings automatically.

Run the sfsconfig command on the head node, by entering the command shown in the following

example. In this example, south is the name of an HP SFS system that the HP XC nodes will access:

# sfsconfig --server south all

The sfsconfig command creates a new /etc/modprobe.conf.lustre file that contains the

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

When the script has completed, examine the /etc/modprobe.conf.lustre file and the

/etc/modprobe.conf file on the head node to ensure that the options lnet settings and the lquota

settings have been added (see Appendix B for more information on the settings).

If the head node has a different number of Gigabit Ethernet devices than the other nodes in the HP XC

cluster, the sfsconfig command may have added tcp entries to the options lnet settings on the head

node that are not appropriate for the other nodes. If this happens, edit the

/etc/modprobe.conf.lustre file on the head node so that the options lnet settings contain a

common set of Gigabit Etherernet devices. This may involve removing the tcp entries if a Gigabit Ethernet

interconnect is not being used.

Note that the sfsconfig command uses the http: protocol to get configuration information from the

HP SFS servers. If the head node does not have access to the HP SFS servers over a TCP/IP network, or if

the servers are offline, the sfsconfig command will not be able to configure the head node correctly, and

you will have to modify the configuration file manually. For instructions on how to do this, see Appendix B.
