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

IMPORTANT:

Upgrade the servers in order of IP address, starting with the server with the highest

numbered address. Then continue to upgrade the servers in descending order of IP

address, with the lowest numbered server being upgraded last.

Do not restart Matrix Server/HP Clustered File System after running the MxFS

migration tool in step 1, as the resulting state change may not be captured in the

export.

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

earlier with the MxFS migration package. The tool first halts vhost NFS serving

(you may see error messages; they can be ignored). The tool then exports the

MxReg data to the shared data path that you specified for the mximport tool

when you upgraded the first node. If you did not specify a shared data path,

the tool will export the MxReg data to the /var/opt/polyserve/run directory

on the server.

# /opt/polyserve/tools/mxfs_upgrade_prep.sh

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/

polyserve/run (or /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/polyserve/

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/

polyserve/run/mxreg_export_backup.xml on the first upgraded

server. Rename this file to mxreg_export.xml.

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

and select Disable.)

3. 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.
