Deployment Guide

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 supported controllers, see Dell
Systems Software Support Matrix at dell.com/openmanagemanuals.
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
Q: Why cannot I see any controllers using RAIDCFG?
A: Ensure that the RAID controllers can be seen in the BIOS during POST. If the BIOS does not detect the controller, then RAIDCFG
does not detect it. Also ensure that the controller is set to RAID mode and not any other mode in the controller BIOS.
Q: What is span length?
A: Span length enables you to select the number of array disks in a span for the nested RAID levels (RAID-10, RAID-50, and
RAID-60). The default (minimum permissible) span length value is 2 for RAID-10, 3 for RAID-50, and 4 for RAID-60.
Q: PARTCFG cannot enumerate the virtual disks created by RAIDCFG. What must be done?
A: A reboot is required for PARTCFG to enumerate virtual disks after creating a virtual disk using the RAIDCFG command.
SYSCFG questions
Q: Can I use the SYSCFG utility to configure Point-to-Point Protocol (PPP) over the serial port to access my RAC?
A: No. The Baseboard Management Controller (BMC) firmware does not support PPP configurations for the serial port.
Q: The SYSCFG utility --lancfgparams option has suboptions that configure the IP address, Gateway, and Subnet Mask for
the system BMC. There is also a MAC address. Are these the same as the operating system network parameter of the
managed system?
A: No. The Baseboard Management Controller (BMC) has its own IP address, Gateway, Subnet Mask, and MAC address values.
