C Core I/O Card Utilities

This appendix provides information on core I/O cards that need additional configuration.

Integrated RAID

Use Integrated RAID (IR) where either storage capacity, redundancy, or both of a RAID
configuration are required. Two components of IR are:
Integrated Mirror (IM)

Global Hot Spare

Integrated Mirror

The advantage of an IM is there is always a mirrored copy of the data. An IM provides data
protection for the system boot volume to safeguard critical information such as the operating
system on servers and high performance workstations. An IM supports two simultaneous mirrored
volumes, making an array, providing fault-tolerant protection for critical data. Typically, one of
these volumes is the boot volume. If a disk in an IM fails, the hot swap capability enables the
volume to be easily restored by replacing the failed disk. The firmware then automatically re-mirrors
to the replaced disk.
Global Hot Spare
Each SAS controller can have one global hot spare disk available to automatically replace a
failed disk in the one or two IM volumes configured on the controller. The hot spare makes the
IM array more fault tolerant. Up to two IM volumes are supported per SAS controller plus the hot
spare.

section.

MPTUTIL Utility

The mptutil utility enables you to update the adapter flash memory with the EFI driver and
HBA firmware. New versions of these images are released periodically.
IMPORTANT:
on a SAS device and the update fails, these files will not be accessible.
To update firmware, follow these steps:
1. Insert the IPF Offline Diagnostics and Utilities CD in the drive and boot to the EFI Shell.
NOTE:

IMPORTANT:
be in the drive to allow device mapping. The EFI utility and firmware image files are located
in the root directory or in a subdirectory on the CD.
2. The CD drive displays in the list of mapped devices as fs0. To change to this device, enter
