Change RAID Configuration

Quantum ships the system configured as, RAID 5, 6-drive configuration. As a best practice, you should not modify or reconfigure the RAID 5. If you must reconfigure the system, Quantum recommends that a qualified person performs the reconfigure procedure.
Caution: If you reconfigure the RAID 5, ensure to download your data from the system (drive magazine). All data on the drive magazine will be lost during the reconfigure process.
Factory new magazines have the file system initialized. Creating a file system on the magazine is not needed. If a file system is created, it will take up to 24 hours to complete. If you remove power from the system during file system creation, the file system will become corrupted and will need to be recreated.
Here is a representative example of data versus parity in a RAID 5 and RAID 6 configuration using 10TB drives.
- RAID 5 (6 10TB drives)
- Data (5 drives): 50TB
- Parity (1 drive): 10TB
- RAID 6 (6 10TB drives)
- Data (4 drives): 40TB
- Parity (2 drives): 20TB
Recommended configurations:
- RAID 5 is the recommended configuration because it:
- Is dependable and basically only uses the equivalent of one (1) drive for parity.
- Allows data storage on five (5) drives.
- Can lose one (1) drive and still allow data access.
- RAID 6 is often used because it:
- Is very dependable and basically uses the equivalent of two (2) drives for parity.
- Allows data storage on only four (4) drives.
- Can lose two (2) drives and still allow data access.

Note: We are using a representative AC system to perform this procedure.
Complete the following procedure:
-
Ensure the system is powered off.
-
Connect an Ethernet cable from your computer to the IPMI port on the back of the system.
- Set up your computer so that you can communicate with the system.

Note: This is a representative example of setting up your computer to communicate with the system. Depending what type of software you are using, dictates the actual screen presentation.
Complete the following procedure:
-
Access the “Control Panel” screen and click on “Network and Sharing Center”.
