HP StorageWorks Scalable File Share System Installation and Upgrade Guide Version 2.2

Upgrading a system8–4
If the client node is at HP SFS Version 1.1 or earlier, use the lconf --cleanup command to
unmount all file systems as shown in the following example, where the data file system is unmounted:
# /usr/sbin/lconf --ldapurl ldap://south.my.domain.com
--config data --node client_tcp --cleanup
2. Verify that the file systems have unmounted, by searching for the /proc/fs/lustre directory,
as follows:
# ls /proc/fs/lustre
If the directory exists, the file system software has not unloaded. Complete the unloading as follows:
a. If there are boot-time scripts that mount the file system, disable them.
b. Reboot the client node.
Repeat this process as necessary to unmount the file systems on each client node, then proceed to
Section 8.3.3 to stop the file systems.
For more information on unmounting file systems, refer to the HP StorageWorks Scalable File Share
Client Installation and User Guide.
8.3.3 Step 3: Stopping all file systems
To ensure that no client node can access the file systems served by the HP SFS system during the time that
the software is being upgraded on the servers, you must stop the file systems. Log in to the administration
server and perform the following steps:
1. Enter the command shown in the following example, where data is the file system to be stopped:
sfs> stop filesystem data
2. The file system must be in the stopped or not-stopped state to prevent it from starting the next
time a server is booted. Verify the state of the file system by entering the show filesystem
command, as follows:
sfs> show filesystem data
Name: data
OSTs: ost[3-6]
State: stopped
.
.
.
Repeat these steps for each file system, then proceed to Section 8.3.4 to upgrade the client nodes.
8.3.4 Step 4: Upgrading the client nodes (optional)
When all file system have been unmounted, you can (optionally) proceed to upgrade the HP SFS software
on all client nodes, as described in Chapter 2 and Chapter 3 of the HP StorageWorks Scalable File Share
Client Installation and User Guide.
You may choose not to upgrade the HP SFS software on the client nodes until a later time (see Section 8.1
for information on upgrade paths).
Section 8.3.16 and Section 8.3.21 provide information on configuration changes that are needed
depending on when the client nodes are upgraded.
While the software on the client nodes is being upgraded, you can proceed to Section 8.3.5 and continue
with the process of upgrading the software on the servers.
