4.4 Integrated Striping Firmware This section describes features of the LSI Logic Integrated Striping (IS) firmware. 4.4.1 Host Interface The IS host interface uses the "Message Passing Interface," as described in the Fusion-MPT specification, including Integrated Striping. Through the Fusion-MPT interface, the host operating system has access to the logical IS drive as well as the physical disks. This allows support for domain validation and Ultra320 SCSI expander configuration. 4.4.2 Meta Data Support The firmware supports Meta data describing the IS logical drive configuration stored on each member disk. When the firmware is initialized, each member disk is queried to read the stored Meta data for consistency checking. The usable disk space for each IS member disk is adjusted down to leave room for this data. 4.4.3 SMART Support The IS firmware enables Mode 6 SMART on the IS member disks. Mode 6 SMART requires each physical disk to be polled once per minute. If a SMART ASC/ASCQ code is detected on a physical IS disk, the firmware processes the SMART data, and the last received SMART ASC/ASCQ is stored in non-volatile memory. The IS volume does not support SMART directly, since it is just a logical representation of the physical disks in the volume. 4.4.4 SCSI ID Assignment A single logical drive is presented as the combination of a set of physical member disks. Each individual member disk is hidden and returns a "selection timeout" when accessed. The SCSI Target ID of the IS logical drive is assigned when the logical drive is created. The lowest SCSI ID of the selected disks is used. 4-4 Integrated Striping (IS) Overview Version 1.0 Copyright © 2003 by LSI Logic Corporation. All rights reserved.
