Changing The Raid Level Of A Logical Drive - Adaptec RAID 2130SLP User Manual

Changing the RAID Level of a Logical Drive

As your requirements change, you can change the RAID level of your logical devices to suit
your needs. You may want to do this to add redundancy to protect your data, or improve data
availability for speedier access to your data. See
more information.
Changing the RAID level normally requires one or more disk drives to be added to or removed
from the logical drive. Adaptec Storage Manager won't allow you to continue unless you have
the right number of disk drives available.
To change the RAID level of a logical drive:
In the Enterprise View, click the controller associated with the logical drive.

In the Logical Devices View, click the logical drive.

A wizard opens to help you change the RAID level.

In the example shown in this section, a RAID 1 logical device is being changed to a RAID 5
logical device.
In the Logical Devices panel, select the disk drives you want to use in the modified logical
5
drive.
Adaptec Storage Manager prompts you to select the correct number of disk drives.
If you want to remove a specific disk drive and replace it with another one (for instance,
replace a smaller disk drive with a larger one), click on the disk drive you want to remove.
An X indicates that the selected disk drive will be removed from the logical drive.
