Creating logical drives
Complete the following steps to create logical drives:
1. Click the appropriate Array tab.
2. Select a RAID level from the drop-down list.
v If you are configuring a spanned array, you can set the RAID level only for
the first logical drive you create.
v In addtion to the standard RAID levels (0, 1, 5, x0), you can also create a
simple volume: a single disk drive, non-redundant.
3.
If you do not want to use the maximum size for the logical drive, type the size
in the Data (MB) field.
Notes:
a. Some operating systems have size limitations for logical drives.
Before you save the configuration, verify that the size of the logical
drive is appropriate for your operating system. For more detailed
information, see your operating-system documentation.
b. A logical drive cannot exceed 2048 GB (2 terabytes); the minimum
size is 10MB.
