17 Creating RAID Using Lifecycle Controller
2.1 Important Information
Lifecycle Controller GUI allows you to create only one virtual disk on a controller at anytime. When a new
virtual disk is created from Lifecycle Controller, all the existing virtual disk configurations are lost.
2.2 Best Practices
• Make sure RAID controller is connected to the server and is detected in the POST operation.
• Make sure the HDDs are connected to the RAID controller correctly and RAID controller is able to detect
them.
• To create a RAID, you must be sure about the RAID level you want to select and the number of HDDs to
obe used to create a RAID.
2.3 RAID Levels
The RAID levels are a basic set of RAID configurations that employ the techniques of striping, mirroring, or
parity to create large reliable data stores from general purpose computer HDDs. The most common types
are RAID 0 (striping), RAID 1 (mirroring), RAID 5 (distributed parity), and RAID 6 (distributed dual parity).
RAID levels supported by the Lifecycle Controller RAID Configuration feature are:
• RAID 0 — Striping
• RAID 1 — Mirroring
• RAID 5 — Distributed parity
• RAID 6 — Distributed dual parity
• RAID 10 — Combination of RAID0 and RAID1
• RAID 50 — Combination of RAID0 and RAID5
• RAID 60 — Combination of RAID0 and RAID6
NOTE: RAID levels are supported on the basis of the selected storage controller and the number of
available HDDs connected to it.
2.4 Foreign HDD
An HDD moved from one controller to the other controller is considered as a foreign HDD on the second
controller. Lifecycle controller RAID Configuration feature provides options to clear and ignore the foreign
