The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This document describes the procedure to add new hard drives to an existing Virtual Drives (VD) with and without Redundant Array of Independent Disks (RAID) change.
For instance if you have a VD which has three Hard drives and you want to add three more, the procedure to do so is mentioned in this document.
There are no specific requirements for this document.
The information in this document is based on Cisco UCS-C Servers.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Procedure to Add new Hard Drive
This sections contains the steps to add new hard drive to an existing VD.
Note: You would need to perform the above Procedure task in a Maintainence Window.
Step 1. Reboot the host into webBIOS
When the host computer is booting, this text appears:
Step 2. The Controller Selection window appears, as shown in the image:
Main Menu Screen
The Main Menu Screen displays a menu of items that you can select to display the information and make changes to the RAID arrays attached to the controllers in the server. This screen also shows the current configuration of the physical and logical drives from which you can configure and manage the RAID arrays.
Step 3. Select the desired virtual drive.
Step 4. Select Advanced Operations and click Go, as shown in the image:
Step 5. Add an additional physical drives to the array.
Step 6. Let the virtual drive reconstruct (Reconstruction takes time to complete depending on the amount of disk you are adding)
Migrating the RAID Level of a Virtual Drive
As the amount of data and the number of drives in your system increase, you can use RAID-level migration to change a virtual drive from one RAID level to another. You do not have to power down or reboot the system. When you migrate a virtual drive, you can keep the same number of drives, or you can add drives. You can use the WebBIOS Configuration Utility (CU) to migrate the RAID level of an existing virtual drive.
Note: While you can apply RAID-level migration at any time, LSI recommends that you do so when there are no reboots. Many operating systems issue I/O operations serially (one at a time) during boot. With a RAID-level migration running, a boot can often take more than fifteen minutes.
