Users Guide

When dealing with SAS devices, the array disk location is displayed as channel:target:enclosure. It is
possible to have the enclosure value as non-zero. If the enclosure has a non-zero value, then all three
numbers (channel, target, and enclosure) have to be included on the command line.
Q: Do I need to specify RAID type and size when creating virtual disks?
A: No. The default RAID type is RAID 0. If RAID size is not provided, the maximum size allowed for virtual
disk is created. The mandatory fields required to create virtual disks are the controller slot ID and the
array disks.
Q: What is a hot spare (failover drive)?
A: A hot spare is an extra and unused disk drive that is part of an array disk subsystem. A hot spare is
always in standby mode. If a disk failure occurs, the hot spare replaces the failed drive without
interrupting the system.
Q: What is mr2kserv.exe?
A: The mr2kserv.exe is a service needed to configure all LSI RAID controllers in Windows PE. It provides
Plug and Play support.
Q: What features have changed from the MS-DOS version of RAIDCFG to the Windows PE and
embedded Linux versions?
A: Windows PE and embedded Linux version of RAIDCFG support new controllers. For the list of

Features that have been removed from the MS-DOS version include:
• The --name and --wait options in the create command
• The --runlocation and the --scratchlocation options
• The --getpercentcomplete environment variables
Q: What is the minimum virtual disk size that I can create?
A: For PERC 5 controllers:
• RAID 0: 100 MB
• RAID 1: 100 MB
• RAID 5: 100 MB
For PERC 6 controllers:
• RAID 0: 100 MB
• RAID 1: 100 MB
• RAID 5: 100 MB
• RAID 6: 100 MB
• RAID 60: 100 MB
