Creating and Managing
Arrays & Partitions
Using SAM, you can create and manage arrays and partitions. You can
perform the following array-related functions:
• Create arrays (see page 67 )
• Manage arrays (see page 74 )
• Manage partitions (see page 78 )
• Manage spares (see page 82 )
5.1 Creating Arrays
You can create an array anytime you have enough available disk drives
for the array type you want to create. One SM module owns each array
you create. For most purposes, which SM module owns an array does
not matter. SAM automatically selects the owner (or you can select the
owner yourself) and balances the number of arrays each SM owns.
When an SM module fails, the other SM module assumes temporary
ownership of the failed SM’s arrays and dedicated spares. For more
information about how the SM modules work together see section
2.10 ,
"Understanding how the SMs Work Together" on page 41 .
The maximum size for any array is 2 TB. Figure 45 describes the drive
requirements for each RAID level.
