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-numbered 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
Before starting the upgrade, be sure to complete all required actions specified earlier
in the “Upgrade considerations” section. Also be sure to review all release notes to
become familiar with changes in the operating system, HP Scalable NAS, and
MxDB-Oracle-HiAv. For more information about the commands used in this procedure,
see the HP Scalable NAS File Serving Software command reference guide.
To perform the upgrade, complete the following steps, one node at a time.
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. As user oracle, move any MxDB-Oracle-HiAv services that are active on the
server to another node, for example, the first backup node. Using the following
mxdb command, reorder the list of nodes configured for the Virtual Oracle
Service, making sure that the node being upgraded is not specified first in the
list of IP addresses.
$ mxdb -d <sid> -m ”IP:IP:IP:IP”
2. As user root, disable the server:
# mx server disable <server>
3. If quotas are configured on PSFS filesystems, back up the quota information.
See PSFS filesystems, page 18.
4. Stop Matrix Server on the server:
# /etc/init.d/pmxs stop
