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

Pre-upgrade: MxFS migration package
Install the MxFS migration package
The MxFS migration package should be installed on all nodes in the cluster before
upgrading to 3.7.0. The package includes tools that package and save the MxReg
registry information on each node. The MxFS migration package is provided in the
RPM mxfs-migration-3.5.1-<xxxx>.<arch>.rpm, which is included in the
product distribution and is also available as a stand-alone package in your download
area on www.hp.com.
Install the package as follows on each node:
# rpm -i <mountpoint>/mxfs-migration-3.5.1-<xxxx>.<arch>.rpm
Overview of the migration process
The MxReg registry information includes the NFS export group configuration and the
MxReg state information. There are three parts to the migration of the data:
• When upgrading the first node, you will be prompted by the mximport tool to
specify a location to store the migrated data.
• When upgrading subsequent nodes, you will need to run a script that copies the
MxReg data from those nodes to the location identified for mximport during the
upgrade of the first node.
• When all nodes are upgraded, HP Scalable NAS creates the new mxds datastore
on the 3.7.0 cluster.
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.
