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

NOTE:
If a server is accidentally upgraded out of order, when a higher-number server joins
the cluster, the servers still running the old version of Matrix Server will think they
need to leave the cluster and will no longer send configuration and status updates.
To correct this problem, stop HP Scalable NAS on the node that was upgraded out
of order. Continue upgrading the other nodes before starting HP Scalable NAS on
that node.
Upgrade procedure
To perform the upgrade, complete the following steps.
IMPORTANT:
Upgrade the server with the highest IP address first. Then continue to upgrade the
servers in descending order of IP address, with the lowest numbered server being
upgraded last.
1. Disable the server on the Management Console. (Select the server, right-click,
and select Disable.)
2. If quotas are configured on PSFS filesystems, back up the quota information.
See PSFS filesystems, page 18.
3. Stop Matrix Server 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.
