Step 5 - Additional functions

Cluster setup requirements

Before you configure the NAS Gateway 300 nodes for clustering, ensure that the
following requirements are met:

NAS Gateway 300 User's Reference
At this point you can add users, file shares, and complete other
configuration tasks to improve operations of the NAS Gateway 300 in a
cluster environment.
1. Add users (see "Creating users" on page 42).
2. Add file shares (see "Creating clustered file shares (CIFS and NFS)" on
page 50). Note that you must configure Server for NFS before NFS file
sharing can be used.
For more information on cluster administration, see "Configuring clusters" on
page 41.
Additional functions are available for backup, persistent images, and adding
more storage areas. It is recommended that after you complete the setup
and configuration procedures, you use the Persistent Storage Manager
Disaster Recovery option ("Disaster Recovery" on page 66) or other method
to back up the system configuration in the event of a failure.
Also, it is imperative to use the system shutdown procedure described
in "Shutting down and powering on the NAS Gateway 300" on page 87 to
ensure system integrity.
For more information, see Chapter 6, "Managing and protecting the network
and storage" on page 55.
v A unique NetBIOS cluster name.
v You will need at least seven static IP addresses: five for the node and
cluster setup, and two for each file share served by the cluster. A formula
for the number of static IP addresses is: 5 + (2 x number_of_file shares).
The IP addresses required for node and cluster setup are:
– At least three unique, static IP addresses for the public network: one
for each node (for client access through the PCI NIC adapter) and
one for the cluster itself (the administration IP address).
Table 1 on page 8 shows a summary of the networking information
necessary for the public connection.
– Two static IP addresses for the cluster interconnect on a private
network or crossover, through the onboard Ethernet adapter. The
default IP addresses for the private network adapters are 10.1.1.1 for
the first node in the cluster, and 10.1.1.2 for the node that joins the
cluster. (The top node in the NAS Gateway 300 is considered the first
node, and the bottom node is considered the joining node.)
Notes:
1. If you are not the system administrator, contact that person for the
applicable IP addresses.
2. Each node in a cluster must join the same domain and be able to
access a Primary Domain Controller (PDC) and DNS server, but it is not
required that the nodes log into the domain.
