Configuring RAID
In some circumstances, your RAID 5 configuration may need to be rebuilt. Common reasons for re-configuring the RAID 5 include:
- Adding storage
- Multiple drive failures
- RAID corruption
This article will outline how to configure RAID 5 setup using the MegaRAID WebBIOS of a DW Blackjack® Server with RAID.
**NOTE: Prior to booting up the system, ensure that all drives for the RAID are installed in their bays. It is highly recommended that all HDDs involved share the same manufacturer and model of hard drive.
Supported/Affected Devices
- DW Blackjack® P-Rack Series
- DW Blackjack® E-Rack Series
