Error and warning messages include instructions for correcting the configuration errors.
Appendix A Electrostatic Discharge A discharge of static electricity from a finger or other conductor may damage printed circuit boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. Preventing Electrostatic Damage To prevent electrostatic damage, observe the following precautions: ■ Avoid hand contact by transporting and storing parts in static-safe containers.
A-2 Compaq Integrated Smart Array Controller User Guide Grounding Methods There are several methods for grounding. Use one or more of the following measures when handling or installing electrostatic-sensitive parts: ■ Use a wrist strap connected by a ground cord to a grounded workstation or the computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm +/- 10 percent resistance in the ground cords. ■ Use heel straps, toe straps, or bootstraps at standing workstations.
Appendix B Understanding Drive Arrays This chapter provides explanations of drive array concepts, data protection methods, including fault-tolerance options, and data reliability features of the Integrated Smart Array Controller. Before you configure your Integrated Smart Array Controller, review the following general information so that you are familiar with the terms and concepts required for configuration.

Drive array with two logical drives and six physical drives The same physical drives may also be arranged into separate arrays as illustrated in the figure below. Both arrays can be managed by the same controller.
B-4 Compaq Integrated Smart Array Controller User Guide Drive Arrays Drive arrays on the Integrated Smart Array Controller have several important attributes: ■ A single array cannot span more than one Integrated Smart Array Controller. ■ A single Integrated Smart Array Controller can control multiple arrays. ■ Arrays must have at least one and may have up to 15 physical drives. ■ Arrays consist of at least one and may have up to 32 logical drives with a maximum of 32 logical drives per controller.
Understanding Drive Arrays B-5 Drive Array Benefits Using drive arrays with the Integrated Smart Array Controller has several important benefits: ■ Data protection ■ Performance enhancement ■ Capacity changes ■ Drive movement ■ Data reliability Data Protection The Integrated Smart Array Controller provides several options for producing data redundancy in a more reliable system, including distributed data, fault-tolerance methods, assigning online spares, and rebuilding data automatically to onlin
B-6 Compaq Integrated Smart Array Controller User Guide The fault-tolerance method you choose affects the amount of available disk storage capacity and the performance of your drive array. The following table lists all supported RAID levels for Integrated Smart Array Controller, and it illustrates how the fault-tolerance method you select affects performance and capacity.
Understanding Drive Arrays B-7 CAUTION: RAID 0 has no data protection. You must rely on backups in case of hardware failure on drives with no fault tolerance. Distributed Data Guarding (RAID 5) Distributed data guarding, also called RAID 5, stores parity data across all the drives in the array. Spreading the parity across all the drives allows simultaneous read. If a drive fails, the controller uses the parity data and the data on the remaining drives to reconstruct data from the failed drive.
B-8 Compaq Integrated Smart Array Controller User Guide Drive Mirroring and Striping (RAID 1 and RAID 0+1) Drive mirroring, also called RAID 1, is the highest performance and highest fault-tolerance RAID method. RAID 1 is the only option offering fault-tolerance protection if only two drives are installed or selected for an array. Drive mirroring creates fault tolerance by storing two sets of duplicate data on a pair of disk drives.
Understanding Drive Arrays B-9 No Fault Tolerance (RAID 0) RAID 0 does not provide fault tolerance. This level of RAID stripes data across all the drives of the array, but it does not incorporate a method to create redundant data. Therefore, if you choose this RAID option for any of your logical drives, you will experience complete data loss for that logical drive if one physical drive fails.
B-10 Compaq Integrated Smart Array Controller User Guide Performance Enhancement Drive arrays allow data access performance to be enhanced dramatically over nonarrayed drives. In addition, the Integrated Smart Array Controller has several other performance enhancement features that are discussed here. Distributing Data and Data Striping Distributing data makes it possible to access data concurrently from multiple drives in an array. This yields I/O rates many times faster than nonarrayed drives.
Understanding Drive Arrays B-11 Concurrent I/O Request Servicing The Integrated Smart Array Controller has the capability to service hundreds of I/O requests at a time. For example, if you request data that resides on the first drive and another user requests data that resides on the second drive, the controller can deliver both pieces of information concurrently. The following figure illustrates concurrent request servicing. User 1 Request User 2 Request User 3 Request User 4 Request Figure B-8.
B-12 Compaq Integrated Smart Array Controller User Guide Bus Master Data Transfers The Integrated Smart Array Controller is a bus master device that takes control of the PCI bus during high-speed transfers. This allows the system processor to handle application processing or other types of tasks. Data transfer occurs at rates of up to 132 MB/s on the PCI bus.
Understanding Drive Arrays B-13 Adding Storage Capacity Storage capacity can be increased in two ways: ■ Capacity Expansion–Adding physical drives and creating new logical drives. ■ Capacity Extension–Adding physical drives and growing the existing logical drive (without adding new logical drives). Array Configuration Utility will allow users to extend (increase) the size of existing logical drives under any operating system. However, only Windows NT 4.
B-14 Compaq Integrated Smart Array Controller User Guide When initiated by the Array Configuration Utility, the Integrated Smart Array Controller automatically redistributes the data in the original logical drive to a logical drive that spans all of the physical drives in the array, including the added drives. The room left over is used to increase the size of a logical drive or create additional logical drives, also spanning all physical drives. The extended logical drive is within the larger drive array.
Understanding Drive Arrays B-15 It is not necessary for all logical drives in an array to be the same size or even have the same fault-tolerant configuration. Each logical drive is treated as a separate entity no matter how many physical drives it crosses. Each may be configured as best suits your needs.
B-16 Compaq Integrated Smart Array Controller User Guide Disk Drive Capacity Upgrades Additional storage space may be obtained with the same number of physical drives in a fault-tolerant configuration by replacing these drives with others of higher capacity. By replacing the drives one at a time, the data on the new drive is re-created from redundant information on the remaining drives. After each new drive has been rebuilt, the next can be replaced.
Understanding Drive Arrays B-17 Dynamic Sector Repairing Using the dynamic sector repairing process, the controller automatically remaps any sectors with media faults it detects either during normal operation or during auto reliability monitoring. Drive Parameter Tracking Drive parameter tracking monitors more than 15 drive operational parameters and functional tests.
B-18 Compaq Integrated Smart Array Controller User Guide Automatic Data Recovery After you replace a failed drive, automatic data recovery reconstructs the data and places it on the replaced drive. This allows a rapid recovery to full operating performance without interrupting normal system operations. In general, the time required for a rebuild is approximately 15 minutes per gigabyte.
Understanding Drive Arrays B-19 Drive Indicators OK to remove drive if not part of fault-tolerant configuration OK to remove failed drive DO NOT remove drive DO NOT remove drive DO NOT remove drive DO NOT remove drive OFF Online Drive Access Drive Failure Figure B-11.
B-20 Compaq Integrated Smart Array Controller User Guide Software-Based Drive Mirroring IMPORTANT: Compaq strongly recommends using hardware-based fault tolerance instead of software-based fault tolerance. Hardware-based fault tolerance provides a much more robust and controlled environment for fault-tolerance protection. Some operating systems support software-based drive mirroring as a fault-tolerance feature.
Understanding Drive Arrays B-21 Recognizing a Drive Failure A drive failure can be recognized by the system operator in one of several ways: ■ Amber LED will be illuminated on failed drives in a hot-plug tray. This, however, assumes the storage system is powered on and the SCSI cable is working. Note that the amber LED may be illuminated briefly when a hot-plug drive is inserted; this is normal.
B-22 Compaq Integrated Smart Array Controller User Guide Fault Tolerance and Drive Failure In case of a drive failure, the condition of the logical drive will vary depending upon the fault-tolerance method used. Because a single array of physical drives can contain multiple logical drives with different fault-tolerance methods, conditions of each logical drive on the same array are not necessarily the same.
Understanding Drive Arrays B-23 A RAID 5 (Distributed Data Guarding) Logical Drive RAID 5 logical drives: ■ Can sustain a single drive failure. The logical drive will be in a “regenerating” condition if one drive is failed. ■ Will be in a “failed” condition if more than one drive is failed. ■ Will be in a “rebuilding” condition if a previously failed drive has been replaced and the replacement drive is rebuilding.
B-24 Compaq Integrated Smart Array Controller User Guide Before replacing non-hot-plug drives, ensure that system power is Off. On all non-hot-plug drives, be sure to check the SCSI ID jumpers to make sure that the correct drive is being replaced. CAUTION: Replacing the wrong physical drive may compromise fault tolerance and result in data loss. Also, be sure that the SCSI ID jumpers are set to the same SCSI ID on the replacement drive.
Understanding Drive Arrays B-25 In general, the time required for a rebuild is approximately 15 minutes per gigabyte. The actual rebuild time, however, is dependent upon the Rebuild Priority set, the amount of I/O activity occurring during the rebuild operation, the number of drives in the array (RAID 5) and the disk drive speed.
B-26 Compaq Integrated Smart Array Controller User Guide In cases of legitimate drive failure, once copies of important data have been made (if possible), replace any drives that have failed to prevent further drive problems in the future. After these (multiple) drives are replaced, the fault tolerance may again be compromised, power may need to be cycled, and the 1779 POST message may again be displayed. Press F2 to reenable the logical drives, re-create your partitions, and restore all data from backup.
