Name Arrays
Naming an array can be a useful practice to perform backups. It allows an array in the BIOS Configuration
Utility to be easily identified.
To name an array
1.
In the Array View section of the Array Status window, click on the array to select it.
2.
Right-click on the array and select
Name
. The Array Name dialog box appears.
3.
Type the desired name in the Array Name dialog box. Click
OK
.
NOTE:
The specified name appears in the Array List and in the BIOS Configuration Utility.
NOTE:
The following characters are not allowed in the array name:
TIP:
Names can be up to 30 characters long. However, the BIOS Configuration Utility displays only 17 of
those characters.
Transform Arrays (supported only by RAIDCore VST)
With the Transform task, an array can be transformed from one RAID level to almost any other RAID level.
The array can be expanded dynamically, even under I/O load.

Table 34 Issues and Recommendations for Transforming Arrays
Issues Recommendations
Array size An array cannot be transformed to a smaller-sized array. New arrays must be
either the same capacity or larger.
Array size limits The array size of the transformed 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.
Disk failure during a
Transform If a disk fails while the Transform task is in progress, no data is lost as long
as the source and destination RAID levels are redundant. If a spare has been
assigned to the destination array, a fail-over task will start as soon as the
Transform completes, provided the spare is available after the Transform.
Multiple arrays If there are multiple arrays, it might not be possible to transform some of the
arrays to a larger size. If, in the future, an array needs to be expanded in size,
it is best to configure the available space as a single array.
