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

Creation of the new mxds datastore
When the upgrade has been completed on all servers and the cluster is running, HP
Scalable NAS will create the mxds datastore and import the NFS state information
saved in the mxreg_export.xml file to the new datastore. NFS serving will start
automatically when the process is complete.
Upgrade the first server
The server with the highest IP address should be upgraded first. Use this procedure
to upgrade the server.
1. Disable the server on the Management Console. (Select the server, right-click,
and select Disable.)
2. Back up the MxFS-Linux/FS Option for Linux configuration and any quotas
information on PSFS filesystems. See Back up the cluster configuration, page 15.
3. Stop Matrix Server/HP Clustered File System on the server:
# /etc/init.d/pmxs stop
4. Back up the cluster configuration on the server, as described under Back up the
cluster configuration, page 15. If you are using the HP Samba deployment kit,
also save the Samba configuration files (see Samba configuration, page 16).
5. Perform a fresh installation of the operating system. See Appendix A, page 93
for operating system information.
6. Install the kernels RPM corresponding to your OS. This RPM contains the HP
Scalable NAS binary, source, and debug kernels.
# rpm -i pmxs-<os>-kernels-3.7.0-<xxxx>.<arch>.rpm
The installation creates the directory structure /opt/polyserve/lib/kernels.
RPMs for the binary, source, and debug kernels are in the kernels directory.
