ATTENTION
Before upgrading, check the accompanying release notes for any specific
actions to take for the particular software upgrade package or install image.

Performing minor and major release upgrades

The following description applies to a minor or a major release upgrade.
To upgrade the Nortel SNAS you will need the following:
•Access to one of your Nortel SNAS devices through a remote
connection (Telnet or SSH), or a console connection.
•The software upgrade package, loaded on a TFTP/FTP/SCP/SFTP
server on your network.
•The host name or IP address of the TFTP/FTP/SCP/SFTP server. If
you choose to specify the host name, note that the DNS parameters
must have been configured. For more information, see “Configuring
DNS servers and settings” (page 276).
•The name of the software upgrade package (upgrade packages are
identified by the .pkg file name extension).
The set of installed Nortel SNAS devices you are running in a cluster
cooperate to give you a single system view. Thus, to perform an upgrade,
you only need to connect to the MIP of the cluster. The upgrade will
automatically be executed on all the Nortel SNAS devices in operation at
the time of the upgrade. All configuration data is retained.
You can access the MIP by a Telnet or an SSH connection.
ATTENTION
Telnet and SSH connections to the Nortel SNAS are disabled by default, after
the initial setup has been performed. For more information about enabling Telnet
and SSH connections, see “Configuring administrative settings” (page 281).
When you have gained access to the Nortel SNAS, download the software
image (see “Downloading the software image” (page 369)).
