Appendix C

Creating and Managing
Arrays & Partitions

Using the Disk Array Administrator, you can create and manage arrays and partitions. You can perform
the following array-related functions:

• Create arrays (see

page 105

)

• Manage arrays (see

page 116

)

• Manage partitions (see

page 133

)

C.1 Creating Arrays

You can create an array anytime. You can create arrays from either SM A or SM B. Arrays you create
from one SM are not visible through the RS-232 or Ethernet port of the other SM. However, all unused
disk drives connected to all LRC I/O modules and all pool spares are available to both SMs.

The maximum size for any array is 2 TB.
