4 Cluster Cabling and Setup

Connect Shared Storage

NOTE NetRAID channels must not cross. That is, make sure to connect channel 0, 1, and 2 from
one HP NetServers through the storage cabinet to channel 0, 1, and 2 respectively on the
second HP NetServer. Follow the cabling diagram(s) in the configuration guide carefully.
It is a good idea to number or color-code the cable ends for the channels used. In this
way, when a cluster device is removed for maintenance or repair, it can easily be
reconnected without danger of crossing channels.
CAUTION
To prevent damage to device cables before extending any racked device from the rack,
check that there is either sufficient cable length or disconnect the cables. Also make sure
to extend the anti-tip bar at the bottom front or rear (if applicable) of the rack before
extending any devices.

Cabling Guidelines

Use the Right Cables. Only cables specified in your Configuration Guide are to be used for connecting
NetServers and shared storage.
Use Diagrams in the Configuration Guide. Cabling a cluster requires that SCSI connections be made
in a specific manner so that the appropriate redundancy and therefore, high availability requirements are
meet. Use the diagrams in the applicable Configuration Guide to cable the cluster configuration.
Rack Layout. Cables bundled with a clustered system dictate the stacking or arrangement of devices in
the rack. When defining your cluster using HP Rack Assistant, a rack layout should have been printed.
Lay out devices in the rack according to the Rack Assistant layout to ensure that all required cable
connections can be made and that the layout conforms to usability and safety standards.

Power Down Shared Storage

If Shared Storage power is on, make sure that it is turned off before continuing.
