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

NOTE:

When the migration tool has been run on the last node to be upgraded, note the

following: If the MxReg data was exported to the local /var/opt/hpcfs/run

directory on the servers, copy the mxreg_export.xml ﬁle from that directory on

the last server migrated with mxfs_upgrade_prep.sh to the /var/opt/hpcfs/

run directory on the first node that was upgraded to 3.7.0. If you speciﬁed a shared

path when you ran the mximport tool, it is not necessary to copy the ﬁle to the

server running 3.7.0; however, HP recommends that you back up the ﬁle.

If you did not specify a shared path for the MxReg data and 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.

1. Run the MxReg migration tool, mxfs_upgrade_prep.sh, which was installed

earlier with the MxFS migration package.

# /opt/hpcfs/tools/mxfs_upgrade_prep.sh

The tool first halts vhost NFS serving and then copies the MxReg data to the

shared data path you specified in the mximport tool while upgrading the first

server.

2. Disable the server on the Management Console. (Select the server, right-click,

and select Disable.)

3. Back up the FS Option for Linux configuration and any quotas information on

PSFS filesystems. See Back up the cluster configuration, page 15.

4. Stop HP Clustered File System on the server:

# /etc/init.d/pmxs stop

5. Back up the cluster configuration on the server, as described under Back up the

cluster configuration, page 15.

6. Perform a Quick Restore of the 3.7.0 release using the Quick Restore DVD.

7. Set up network connections. (IPs configured on the upgraded node should be

the same as they were before the upgrade.)
