Upgrading HP SFS client software on existing RHEL and SLES 9 SP3 systems 3–21

If a modified version of the python-ldap package is not provided for your client architecture/

distribution on the HP StorageWorks Scalable File Share Client Software CD-ROM for the

version you are upgrading to, you do not need to remove (and reinstall) the python-ldap

package.

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

# rpm -ev lustre-modules-version_number \

lustre-lite-version_number \

python-ldap-version_number \

hpls-lustre-client-version_number \

hpls-diags-client-version_number

4. If you have the optional gm-version_number.rpm file installed, remove it, as shown in the

following example:

# rpm –ev gm-version_number

5. Reboot the client node.

6. Install the new HP SFS client software, as described in Steps 1 through 12 in Section 3.3.2.

7. When you have finished installing the new client software, you can remove the old kernel file as

follows (this is an optional task; removing the old kernel frees up space on the client node):

# rpm -ev kernel-smp-old_version_number

When you have finished upgrading the HP SFS client software, proceed to Section 3.4.2 to run the

sfsconfig command on the client node.

3.4.2 Step 2: Running the sfsconfig command after upgrading the software

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

the sfsconfig command on the client node.

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

• 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.

• The sfsconfig command 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).

To run the sfsconfig command, enter the following command:

# sfsconfig all

When the script has completed, verify that the configuration files have been updated:

• Examine the /etc/modprobe.conf.lustre or /etc/modules.conf.lustre file and the /

etc/modprobe.conf or /etc/modules.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.
