Using the RAID Configuration Utility program
Use the RAID Configuration Utility programs to perform the following tasks:
v Configure a redundant array of independent disks (RAID) array
v View or change the RAID configuration and associated devices
When
you are using the RAID Configuration Utility programs to configure and
manage arrays, consider the following information:
v Hard disk drive capacities affect how you create arrays. Drives in an array can
have different capacities, but the RAID controller treats them as if they all have
the capacity of the smallest hard disk drive.
v To help ensure signal quality, do not mix drives with different speeds and data
rates.
v To update the firmware and BIOS code for an optional ServeRAID SAS
controller, you must use the IBM ServeRAID Support CD that comes with the
ServeRAID controller.
