Upgrading HP SFS client software on existing HP XC systems 2–11

NOTE: 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.

When you have finished running the sfsconfig command, proceed to Section 2.3.3 to update the golden

image.

2.3.3 Step 3: Updating the golden image

Complete the upgrade process, by performing the following steps:

1. Mount the file systems by entering the following commands:

# service sfs gensfstab

# service sfs start

2. Update the /etc/modprobe.conf file.

When you install and configure the HP SFS client software on the head node, the

/etc/modprobe.conf file is changed. This file is not updated in the golden image and you must

therefore add the following line to the existing /etc/modprobe.conf file in the golden image (that

is, the /var/lib/systemimager/images/base_image/etc/modprobe.conf file):

# include /etc/modprobe.conf.lustre

3. 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.

4. Create a new or updated golden image, by running the cluster_config utility. For information on

running this utility, refer to the HP XC System Software Administration Guide.

The cluster_config utility creates a new or updated new golden image, which includes the

updated HP SFS software and the updated /etc/sfstab.proto, /etc/modprobe.conf, and

/etc/modprobe.conf.lustre files.

If all of the client systems that access an HP SFS system have now been upgraded to HP SFS Version 2.2,

proceed to Section 2.3.4 to disable Portals compatibility.

2.3.4 Step 4: Disabling Portals compatibility

If some of the client systems that access the HP SFS system have not yet been upgraded to HP SFS

Version 2.2, skip this step.

If all of the client systems that access the HP SFS system have now been upgraded to HP SFS Version 2.2,

Portals compatibility is no longer needed on the servers or the client systems. You must disable Portals

compatibility on the HP SFS servers and set the portals_compatibility attribute to none on all of the

client systems that access the HP SFS servers.

To disable Portals compatibility on the servers and client systems, perform the following steps. Note that you

must perform these steps on each client system that accesses the HP SFS system:

1. Unmount all Lustre file systems on the client nodes.

2. Disable Portals compatibility mode on the HP SFS servers; for information on how to do this, refer to

Chapter 8 of the HP StorageWorks Scalable File Share System Installation and Upgrade Guide,
