3.7.0 HP StorageWorks HP Scalable NAS File Serving Software upgrade guide HP Scalable NAS for Linux (AG513-96005, October 2009)

Migration actions on the first server

During the upgrade of the first server, you will need to run a tool, mximport, that

asks for the following information:

• The hostname and root password for a server running the 3.5.1 release.

• The Matrix Server or HP Clustered File System admin password for the 3.5.1

cluster.

• A location to store MxReg data. HP recommends that you specify a path on a

PSFS filesystem on the shared storage. The filesystem should be a persistent mount.

NOTE:

If you do not specify a PSFS filesystem, mximport uses the default location, which

is the local /var/opt/polyserve/run (or /var/opt/hpcfs/run)

directory on the server.

Although the mximport tool copies much of the cluster configuration, it does not

copy the MxReg data. It simply creates a structure for this data that will be used

by the remaining servers as they are upgraded.

Migration actions on the second and subsequent servers

The migration package includes a tool called mxfs_upgrade_prep.sh that must

be run during the upgrade of the remaining servers. This tool creates a file called

mxreg_export.xml that contains the MxReg data from the server. The file is placed

in the location indicated during the execution of mximport on the first server (either

a PSFS filesystem or the default local directory).

NOTE:

If the local directory is used, after running the mxfs_upgrade_prep.sh script

on the last server to be upgraded, you will need to copy the mxreg_export.xml

file from /var/opt/polyserve/run or (/var/opt/hpcfs/run) on that server

to the first server to be upgraded. It is important to do this because the first server

does not have a copy of the file.
