5-24 Compaq StorageWorks RAID Array 4100 User Guide
Create Array Screen
In this screen, all available drives attached to the selected controller are
displayed on the left. Drives assigned to the current array appear on the right.
A port number and SCSI ID identify each physical drive.
To create an array, select the drive or drives to be part of the array, then press
the Assign Drives to Array (top) button. You can also select drives and drag
them to the array. To assign a spare, select the drive to be the spare and then
click the Assign Spare to Array (bottom) button.
Always group physical drives of the same size. If you mix drive sizes, the
RA4000 controller treats all the drives as the same size as the smallest drive in
the array. This results in wasted capacity in the larger drives.
To increase performance, Compaq reconnects installing/distributing drives to
both ports before running the Array Configuration Utility. Select drives for
both ports when creating your array.
