If you select one physical drive with the <Space> key and press <Enter>, StorCon suggests to
create a single drive out of this hard disk drive. See the example in Figure 50.
Figure 50. Create Single Drive
Next, enter the appropriate drive capacity and press <Enter>. See Figure 51. StorCon allows you
to limit the hard disk drive size for this host drive. This becomes important when you configure
disk arrays and you want to ensure that future drives added to the disk array fit in the array (for
replacement purposes). Should a new drive have less than the required capacity, StorCon could not
accept it. In this example limit the capacity of each drive to 17000 MB. Any new 18 GB drive
must have at least that capacity.
Figure 51. Drive Size
If you select two or more physical drives with the space bar and press <Enter>, StorCon suggests
the creation of a logical drive of the type Chain. In some literature disk chaining is also called Disk
Spanning. Picture the functioning mechanism of a type Chain logical drive as follows: all hard
disk drives forming the logical drive are linked together one by one in the exact same order in
which they were selected with the space bar. This concatenation can be compared to a chain. If,
for example, the logical drive consists of four hard disk drives with 2000 MB each, the logical drive
will have a capacity of 8000 MB. When data is written to this logical drive, the first hard disk drive
is filled first, then the second, and so on.
Although it is not advisable, logical drives of the type Chain can also be components of array
drives.
