Alternatively, you can enter the following command (enter the command as root user; if you run the

command as any other user, the command only reports the current user’s references):

# lsof /data

2. Unmount all Lustre file systems on the client node that you are going to downgrade, as follows:

# sfsumount -a

3. Remove all of the existing HP SFS RPM files on the client node, except the kernel, in the order in which

they were installed, as shown in the following example:

NOTE: For some distributions, the python-ldap package provided on the source media for

the distribution is not suitable for use with the HP SFS software. For these distributions, HP

provides a modified version of the python-ldap package in the appropriate directory for the

client architecture/distribution combination on the HP StorageWorks Scalable File Share Client

Software CD-ROM.

If a modified version of the python-ldap package is 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 must remove the existing version of the package and install

the appropriate version.

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-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. Enable Portals compatibility mode on the HP SFS system.
