Working with Arrays
Create and Format Arrays
RAIDCore allows the partitioning and creation of as many as eight arrays across installed disks. Portions of
disks can be used to create arrays, at the same time that other arrays use different portions of the same disks.
Before you begin...
Review the issues and recommendations indicated in the following table.
Create an Array
Select an array and cache
1.
From the Array drop-down menu, or by selecting an existing array and right-clicking, select
Create
.
2.
In the Disk List select the disks to include in the array by checking the box next to the desired disks.
NOTE:
Click the
All
button to select all disks, or click the
Unused
button to select those disks that have yet
to be used in an array.
3.
Select an array type from the Type list.
4.
Enter the capacity in the Capacity field.
NOTE:
The maximum available capacity changes with the disks selected, the RAID level, and the sparing
option that is chosen.
TIP:
For creating volumes larger than 2 TB, see Table 51 on page 112.
5.
Select a cache option for the array. The default is Read + Write Back Cache.
TIP:
Also see Create New Arrays: bcadm --create on page 123.

Issues Recommendations
Access to arrays The creation of arrays, even redundant arrays, allows users immediate access to the
arrays, unless the Zero Create option is used during the create.
Array numbers Array numbers are valid only for a given boot, and can be different in the BIOS and
drivers. If a permanent label is required, use the labeling feature described in
Name
Arrays on page 78.
Array size The array size of the new array is limited to 2.199 TB on some versions of Windows
and Linux. Refer to the operating system documentation for details on maximum array
sizes.
Number of arrays In some circumstances, more than eight arrays are possible. They might appear to
function properly, but are not supported by Dot Hill Systems Corp.
System reboot If the system reboots, the creation process continues where it left off.
