Setting Up the Compaq ProLiant Clusters HA/F100 and HA/F200 3-9
Powering Up
Before applying power to the RA4000, all components must be installed and
connected to the storage hub. Hard drives should be installed in the RA4000 so
they can be identified and configured.
The cluster must be powered up in the following order:
1. Storage hub (Power is applied when the AC power cord is plugged in)
2. Storage system
3. Servers
Configuring Shared Storage
The Compaq Array Configuration Utility sets up the hardware aspects of any
drives attached to an array controller, including the drives in the shared
RA4000s. The Array Configuration Utility can initially configure the array
controller, reconfigure the array controller, add additional disk drives to an
existing configuration, and expand capacity. The Array Configuration Utility
stores the drive configuration information on the drives themselves; therefore,
after you have configured the drives from one of the cluster nodes, it is not
necessary to configure the drives from the other cluster node.
For detailed information about configuring the drives, refer to "Running the
Array Configuration Utility" in the Compaq StorageWorks RAID Array 4000
User Guide.
The Array Configuration Utility runs automatically during an Automated
SmartStart cluster installation.
