Before you begin
Log on to the existing Nortel SNAS 4050 device to check the software version and
system settings. Use the
/boot/software/cur command to check the currently
installed software version (for more information, see “Managing software for a
Nortel SNAS 4050 device using the CLI” on page 734). Use the
/cfg/sys/
accesslist/list
command to view settings for the Access List (for more
information, see “Configuring the Access List using the CLI” on page 474).
Do not proceed with the join operation until the following requirements are met.
• Verify that the IP addresses you will assign to the new Nortel SNAS 4050
device conform to Nortel SNA network requirements. For more information,
see “About the IP addresses” on page 51 and “One-armed and two-armed
configurations” on page 40.
• The Access List has been updated, if necessary.
The Access List is a system-wide list of IP addresses for hosts authorized to
access the Nortel SNAS 4050 devices by Telnet and SSH.
If the
/info/sys command executed on the existing Nortel SNAS 4050
shows no items configured for the Access List, no action is required.
However, if the Access List is not empty before the new Nortel SNAS 4050
joins the cluster, you must add to the Access List the cluster’s MIP, the
existing Nortel SNAS 4050 RIP on Interface 1, and the new Nortel
SNAS 4050 RIP on Interface 1. You must do this before you perform the join
operation, or the devices will not be able to communicate with each other.
For information about adding entries to the Access List, see “Configuring the
Access List using the CLI” on page 474.
• The existing Nortel SNAS 4050 and the new Nortel SNAS 4050 must run the
same version of software. If the versions are different, decide which version
you want to use and then do one of the following:
• To change the version on the new NSNAS, download the desired software
image and reinstall the software (see “Reinstalling the software” on
page 763).
