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

16. Load the HP Scalable NAS default HBA driver and verify that the server has
access to the SAN storage. Run the following command to load the driver:
# /etc/init.d/pmxs load
17. Run the following command to see a list of devices and review the output to
verify that the SAN is configured as you expect.
# cat /proc/partitions
18. Run the mximport tool to import the cluster configuration from a node running
3.5.1. The mximport tool automatically collects the necessary configuration
information from the 3.5.1 node and sets a flag on the node being upgraded
to indicate that this is an upgraded node. The pre-upgrade package must be
installed on the 3.5.1 node and the node must be accessible via ssh.
# mximport
mximport asks for the following information: the hostname, the root password
for the 3.5.1 node, and the Matrix Server/HP Clustered File System admin
password for the 3.5.1 cluster. The configuration information is then imported.
If NFS export groups are configured on the 3.5.1 cluster, mximport asks for
a location to store the export group data, including the MxReg NFS state
information. HP recommends that you specify a path on a PSFS filesystem on
the shared storage. The filesystem should be a persistent mount. mximport will
verify that the path is accessible from the 3.5.1 node.
NOTE:
If you do not specify a location on a PSFS filesystem, mximport will use
the default location, which is /var/opt/hpcfs/run on the local server.
After the migration script has been run on the last node being upgraded
to 3.7.0, you will need to copy the mxreg_export.xml file from /var/
opt/hpcfs/run on that server to the first server to be upgraded.
When the mximport operation is complete, HP Scalable NAS will start on the
server.
19. Copy the new license file to /etc/opt/hpcfs/licenses/license on the
server.
