NOTE:
The LUN underlying the basic disk should be presented to only one node of the cluster using selective
storage presentation or SAN zoning, or having only one node online at all times until the physical
resource for the basic disk is established.
In preparing for the cluster installation:
•
All software components listed in the
HP ProLiant Storage Server SAN Connection and
Management
white paper (located on the HP web site at
http://h20000.www2.hp.com/bc/
docs/support/SupportManual/c00663737/c00663737.pdf
) must be installed and the
fi
ber
cables attached to the HBAs before the cluster installation is started.
•
All shared disks, including the Quorum disk, must be accessible from all nodes. When testing
connectivity between the nodes and the LUN, only one node should be given access to the
LUN at a time.
•
All shared disks must be con
fi
gured as basic (not dynamic).
•
All partitions on the disks must be formatted as NTFS.
Network planning
Clusters require more sophisticated networking arrangements than a stand alone storage server. A
Windows NT domain or Active Directory domain must be in place to contain the cluster names, virtual
server names, and user and group information. A cluster cannot be deployed into a non domain
environment.
All cluster deployments have at least six network addresses and four network names:
•
The cluster name (Unique NETBIOS Name) and IP address
•
Node A's name and IP address
•
Node B's name and IP address
•
At least one virtual server name and IP address for virtual server A
•
Cluster Interconnect static IP addresses for Node A and Node B
In multi-node deployments, additional network addresses are required. For each additional node, three
static IP addresses are required.
Virtual names and addresses are the only identi
fi
cation used by clients on the network. Because the
names and addresses are virtual, their ownership can transition from one node to the other during a
failover, preserving access to the resources in the cluster group.
A cluster uses at least two network connections on each node:
•
The private cluster interconnect or “heartbeat” crossover cable connects to one of the network
ports on each cluster node. In more than two node deployments, a private VLAN on a switch or
hub is required for the cluster interconnect.
•
The public client network subnet connects to the remaining network ports on each cluster node.
The cluster node names and virtual server names have IP addresses residing on these subnets.
NOTE:
If the share is to remain available during a failover, each cluster node must be connected to the same
network subnet. It is impossible for a cluster node to serve the data to a network to which it is not
connected.
Protocol planning
Not all
fi
le sharing protocols can take advantage of clustering. If a protocol does not support clustering, it
will not have a cluster resource and will not failover with any cluster group. In the case of a failover,
