Infortrend RAID Controller Manual

Figure 10 - 2 Expansion by Adding Drive
RAID levels supported: RAID 0, 3, and 5.
The new partition must be mapped to a host LUN in order for the
HBA (host-bus adapter) to recognize its presence. If you want to add
the new partition into an existing partition, operating system support
is necessary.
Adding New Drive to a Logical Drive
First select from main menu “View and Edit Logical Drive,” and select
a logical drive to add a new drive to. The drive selected for adding
should have a capacity no less than the original member drive. If
possible, use drives of the same capacity because all drives in the
array is treated as though they have the capacity of the smallest
member drive in the logical array.
Press [ENTER] to select a logical drive and choose “add SCSI drives”
from the submenu. Proceed with confirming the selection.
