Expanding Storage Capacity - Compaq RAID Array 4100 User Manual

E-14 Compaq StorageWorks RAID Array 4100 User Guide

Expanding Storage Capacity

The RA4000 Controller allows the configuration of one or more separate
logical drives into a single drive array. Adding one or more logical drives to an
existing drive array can expand an array. To create the room for the additional
logical drives, more physical drives must be added.
Figure E-9. Begin capacity expansion by adding more physical drives
When initiated by the Array Configuration Utility, the RA4000 Controller will
automatically redistribute the data in the original logical drive to a logical
drive that spans all of the physical drives in the array, including the added
drives. The room left over is used to create additional logical drives also
spanning all physical drives. All logical drives are then included in the drive
array with expanded storage capacity.
