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

NOTE:
If NFS serving does not start, place the mxreg_export.xml file that you backed
up earlier into the directory /var/opt/hpcfs/run (or /var/opt/polyserve/
run). If you did not save the mxreg_export.xml file, a backup is available at
/var/opt/hpcfs/run/mxreg_export_backup.xml on the first server to
be upgraded. Rename this file to mxreg_export.xml.
If NFS serving still does not start, check the log file for the import script in /var/
opt/hpcfs/debug/mxfs_upgrade.log.
A reboot may be necessary to ensure that the system is working as expected.
Reestablish NFS client connections
Because of the changes introduced with the new operating system and the 3.7.0
release, all NFS client connections must be reestablished. One way to do this is to
reboot each client machine after the cluster has been upgraded to the 3.7.0 release.
