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. Table 3–1 describes the drive requirements for each RAID level.
