RAID Management
RAID management is provided by software utilities that manage and configure the RAID
system and MegaRAID Express 500, create and manage multiple disk arrays, control and
monitor multiple RAID servers, provide error statistics logging, and provide online
maintenance. They include:
•
MegaRAID BIOS Setup
•
Power Console 500
•
MegaRAID Manager
• General Alert Module
MegaRAID BIOS Setup
BIOS Setup configures and maintains RAID arrays, formats disk drives, and
manages the RAID system. It is independent of any operating system. See the MegaRAID
Configuration Software Guide for additional information.
Power Console 500
Power Console 500 runs in Windows NT. It configures, monitors, and maintains
multiple RAID servers from any network node or a remote location. See the MegaRAID
Configuration Software Guide for additional information.
MegaRAID Manager
This is a character-based utility that works in DOS, SCI Unix SVR3.2 R4.2, SCO
UnixWare, OS/2 2.x, OS/2 Warp, Linux Red Hat 6.x, and Novell NetWare 3.x and 4.x.
See the MegaRAID Configuration Software Guide for additional information.
Fault-Tolerance Features
The MegaRAID Express 500 fault-tolerance features are:
• automatic failed drive detection
• automatic failed drive rebuild with no user intervention required
• hot swap manual replacement without bringing the system down
• SAF-TE compliant enclosure management
Detect Failed Drive
The MegaRAID Express 500 firmware automatically detects and rebuilds failed
drives. This can be done transparently with hot spares.
Hot Swap
MegaRAID Express 500 supports the manual replacement of a disk unit in the RAID
subsystem without system shutdown.
