Cluster setup requirements
Before you configure the Model 326 nodes for clustering, ensure that the following
requirements are met:
Network requirements
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 7 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 Model 326 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.
3. Each node in the cluster must have at least two network adapters: at
least one for the public network and the other for the private
interconnect.
Shared disk requirements
v
All shared disk arrays and devices, including the quorum disk, must be
physically attached to a shared storage bus.
v
All shared disks must be configured as
basic
(not dynamic) disks.
v
All shared disks
must have the same drive letter
on each node.
v
All partitions on these disks must be formatted with NTFS.
v
All partitions on these disks must also be Primary Partitions.
v
Compression must not be enabled.
Powering off and powering on the Model 326
The clustering function requires special considerations when you need to
power off and power on the Model 326. See “Powering off and powering on
the Model 326” on page 49 for details.
