Installing and configuring HP XC systems2–10

4. Remove all of the existing HP SFS RPM files on the head node in the order in which they were

installed, as shown in the following example:

NOTE: In the example shown here, the python-ldap package is removed. This package

needs to be removed only on HP Integrity systems. Omit this command on all other systems.

# rpm -ev lustre-modules-version_number \

lustre-lite-version_number \

python-ldap-version_number \

hpls-lustre-client-version_number \

hpls-diags-client-version_number

5. Reboot the head node.

6. Install the new HP SFS client software on the head node, using the instructions provided in Steps 1

through 4 in Section 2.2.1.

When you have finished upgrading the HP SFS client software on the head node, proceed to Section 2.3.2

to run the sfsconfig command on the head node.

2.3.2 Step 2: Running the sfsconfig command after upgrading the client software

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

the sfsconfig command on the node.

Running the sfsconfig command alters the contents of configuration files on the head node, as follows:

• The script creates a new /etc/modprobe.conf.lustre file that contains the appropriate

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

• The script updates the /etc/sfstab and /etc/sfstab files as follows:

• Converts any mount directives that use the ldap: protocol to the http: protocol (unless the

-L|--keepldap option is specified). Note that the ldap: protocol is supported in HP SFS

Version 2.2 for backward compatibility; it will not be supported in the next major release of the

HP SFS product.

• Comments out mount directives that use the http: protocol and adds equivalent directives

using the lnet: protocol (unless the -H|--keephttp option is specified).

Perform the following steps:

1. Make a copy of the /etc/sfstab.proto file, as shown in the following example:

# cp /etc/sfstab.proto /etc/sfstab.proto.ldap

2. Enter the sfsconfig command on the head node, as follows:

# sfsconfig all

3. When the sfsconfig command has completed, verify that the configuration files have been

updated, as follows:

•Examine the /etc/modprobe.conf.lustre file and the /etc/modprobe.conf file to

ensure that the options lnet settings and the lquota settings have been added. See

Appendix B for additional information on the settings in the configuration files

•Examine the /etc/sfstab and /etc/sfstab.proto files to ensure that the mount

directives using the lnet: protocol have been added.
