Cluster Installation, Setting Up Networks

Cluster Administration Cluster Installation During the installation process, nodes will be shut down and rebooted. These steps are necessary to guarantee that the data on disks that are attached to the shared storage bus is not lost or corrupted. This can happen when multiple nodes try to simultaneously write to the same disk that is not yet protected by the cluster software. Use Table 14 to determine which nodes and storage devices should be presented during each step.

Shutdown all nodes; power on the first node. Power on the next node after the first node is successfully configured. Complete this process for all cluster nodes. At this point all cluster nodes should be on. To configure the Cluster service on the HP StorageWorks NAS server, an account must have administrative permissions on each node. All nodes must be member servers within the same domain. It is not acceptable to have a mix of domain controllers and member servers in a cluster. Setting Up Networks Each cluster node requires at least two network adapters-one to connect to a public network, and one to connect to a private network consisting of cluster nodes only. The private network adapter establishes node-to-node communication, cluster status signals, and cluster management. Each node's public network adapter connects the cluster to the public network where clients reside. Verify that all network connections are correct, with private network adapters connected to other private network adapters only, and public network adapters connected to the public network. 208 NAS 4000s and 9000s Administration Guide

Cluster Administration

NAS 4000s and 9000s Administration Guide
Cluster Installation
During the installation process, nodes will be shut down and rebooted. These steps are
necessary to guarantee that the data on disks that are attached to the shared storage bus is not
lost or corrupted. This can happen when multiple nodes try to simultaneously write to the same
disk that is not yet protected by the cluster software.
Use
Table 14
to determine which nodes and storage devices should be presented during each
step.
To configure the Cluster service on the HP StorageWorks NAS server, an account must have
administrative permissions on each node. All nodes must be member servers within the same
domain. It is not acceptable to have a mix of domain controllers and member servers in a
cluster.
Setting Up Networks
Each cluster node requires at least two network adapters—one to connect to a public network,
and one to connect to a private network consisting of cluster nodes only.
The private network adapter establishes node-to-node communication, cluster status signals,
and cluster management. Each node's public network adapter connects the cluster to the public
network where clients reside.
Verify that all network connections are correct, with private network adapters connected to
other private network adapters only, and public network adapters connected to the public
network.
