Disk array availability is enhanced if each power cord is connected to a separate ac branch circuit. WARNING! To avoid a fire hazard, the ac branch service must be properly current- protected by either a fuse or a circuit breaker.
Page 21: Disk, Power, And Fan Modules
Product Description Installing Modules Disk, Power, and Fan Modules Use the same installation procedure to install power modules and fan modules. See Figure 5 to determine where to install the module. Figure 6 shows how to install a disk module. To install a disk, power, or fan module, open the front door and follow these steps: CAUTION! The module lever must be pulled all the way out or the module will jam in the slot upon insertion.
Page 22: Controller Module
Product Description Controller Module Controller Module NOTE! If two or more controller modules are connected (daisy chained) to the same SCSI bus (whether in the same disk array enclosure or across two or more disk array enclosures), each controller module on the same SCSI bus must have its own unique SCSI address, which is set by the control panel on the front of the disk array (refer to “Operating the Control Panel”).
Page 23: Suppressing Single-Controller Warning Messages
Product Description Controller Module Suppressing Single-Controller Warning Messages When a single controller disk array is powered on for the first time, the control panel may display a “System Warning” error message, which occurs because only one controller is installed. By default, the disk array assumes that there should be two controllers installed, and therefore it will generate single- controller error messages until you suppress them.

(Shutdown is a single command and has no menu items.) Shutdown makes the array unavailable to the host. When a Shutdown is initiated, the array completes any I/Os in progress, posts array information stored in controller NVRAM to disks in the array, then goes offline.
Page 83: Chapter 4. Concepts And Management
Chapter 4. Concepts and Management This chapter describes in greater detail the concepts and management of the disk array, including features and hardware design of the disk array. This information will give you a better understanding of how the disk array operates, which should help you make some of the decisions involved in managing the disk array.
Page 84: Disk Array Features
Concepts and Management Disk Array Features Disk Array Features This section describes some of the key features of the disk array. Understanding how these features work will allow you to use them to best advantage when managing your disk array. Dynamic Data Migration Unlike most conventional disk arrays, the disk array automatically manages its disks for the optimum balance of performance and storage efficiency.
Page 85 Concepts and Management Disk Array Features Stage 1: Low Data Storage A newly installed disk array will typically have only a small amount of data stored on it. In this case, the disk array has room to keep all data in RAID 0/1. All I/Os can be serviced from RAID 0/1, so disk array performance is optimized.
Page 86 Concepts and Management Disk Array Features Stage 2: Moderate Data Storage As more data is stored, a point is reached where it becomes necessary for the disk array to begin moving or migrating data from RAID 0/1 to RAID 5. Because RAID 5 is more storage efficient, this migration frees up capacity for more data.
Page 87 Concepts and Management Disk Array Features Stage 3: High Data Storage As the disk array nears its maximum storage capacity, most data is stored in RAID 5. The array always reserves a certain amount of capacity for RAID 0/1 to maintain an adequate level of performance. The disk array continues to try to keep the most recently updated data in RAID 0/1, but if the array is near maximum capacity this becomes more difficult.
Page 88: Logical Drives (Luns)
Concepts and Management Disk Array Features Logical Drives (LUNs) The entire capacity of the array is divided into entities called logical drives or LUNs. The host operating system treats each disk array logical drive as an individual disk, subdividing it again if necessary into partitions.
Page 89: Auto Include
Concepts and Management Disk Array Features Auto Include The Auto Include feature of the disk array simplifies the process of adding new disks to your array. New disk capacity can be added to the disk array while it is running, eliminating the need to bring the host computer system down.
Page 90: Auto Rebuild
Concepts and Management Disk Array Features Auto Rebuild Auto Rebuild works in conjunction with Active Hot Spare to provide maximum protection against disk failure. Auto Rebuild allows the disk array to automatically begin rebuilding a failed disk drive, thus restoring data redundancy as quickly as possible. A rebuild priority setting allows you to balance array performance with rebuild speed.
Page 91: Auto Failover
Concepts and Management Disk Array Features Auto Failover To provide maximum hardware redundancy, a second array controller protects the disk array against a single array controller failure. If the first array controller fails, data continues to be available by the use of the second array controller.
Page 92: Shutdown
Concepts and Management Disk Array Features Shutdown The disk array uses a coordinated process called Shutdown to take the disk array offline. The primary function of Shutdown is to copy the contents of the controller NVRAM to the disks. This protects critical data stored in the NVRAM against loss should battery backup for the NVRAM fail in the absence of ac power.
Page 93: Disk Array Hardware
The disk array controller contains the intelligence and functionality required to manage the operation of the entire disk array. The major responsibilities of the disk array controller include: ™ Implementing Hewlett-Packard AutoRAID to ensure optimum performance and cost-efficient data storage.
Page 94 Concepts and Management Disk Array Hardware NVRAM Each controller contains NVRAM (non-volatile RAM) used to store vital operating parameters and mapping information used in managing the array. Because data is spread across the disks, the array controller must have some means of determining where each block of data is located.
Page 95: Disk Modules
Concepts and Management Disk Array Hardware Disk Cache The array controller implements caching during both reads and writes. Separate read and write caches are maintained in DRAM.

Controller batteries are a vital and integral part of maintaining the memory maps during a power loss, or any time your disk array has not successfully completed a...
Page 96 Concepts and Management Disk Array Hardware Using Disks of Different Capacities Disks of different capacities can be installed in the same array, providing maximum flexibility and expandability for your disk array. This makes it easy to increase your array’s data capacity as new, higher- capacity disks become available.
Page 97 Concepts and Management Disk Array Hardware Figure 23. Installing a Second High-Capacity Disk Disk Stamps Because data is distributed across all disks, the array controller must keep track of which disks are installed in the array. To do this, the array controller writes a unique stamp on each disk. The disk stamp includes a unique number assigned to the disk (typically its serial number), and the numbers of the other disks in the disk set.
Page 98: Power Modules
Concepts and Management Disk Array Hardware Power Modules The fully redundant disk array includes three power modules, which provide power to all components in the enclosure. The power modules share the power load equally. If one power module fails, the other two power modules are capable of powering the disk array.
Page 99: Scsi Bus Topology
Concepts and Management Disk Array Hardware SCSI Bus Topology The array controller communicates externally with the host over a fast-wide, differential SCSI bus. Each array controller is addressed by the host as a separate SCSI target; therefore, they must each have different addresses if they are connected to the same SCSI bus.
Page 100: Managing The Disk Array Capacity
Concepts and Management Managing the Disk Array Capacity Managing the Disk Array Capacity This section explains how to manage your disk array efficiently. It concentrates on two primary management tasks: managing capacity and optimizing performance. The overall capacity of the disk array can be configured in a variety of ways. Depending on your system needs, you can configure the disk array capacity to provide maximum available capacity, improved performance, or optimum protection from disk failure.
Page 101: Sample Capacity Allocation
Concepts and Management Managing the Disk Array Capacity Sample Capacity Allocation The following example illustrates how the disk array uses capacity in a typical configuration. In this example there are eight disks installed in the array: four 2-Gigabyte disks and four 1-Gigabyte disks. Active Hot Spare is enabled for maximum data protection.
Page 102 Concepts and Management Managing the Disk Array Capacity Some General Rules Regarding Capacity Allocation Building on the information provided in the preceding example, there are some general rules you can follow to achieve the most efficient use of your disks capacity. Using disks of all the same size in the array produces the most efficient use of capacity.
Page 103: Capacity Management Strategies
Concepts and Management Managing the Disk Array Capacity Capacity Management Strategies The way you decide to configure your disk array capacity will be determined by your system needs and your disk array management strategy. Are you willing to sacrifice maximum protection against disk failure for increased capacity? Is performance an issue? Table 3 describes the steps you can take to achieve your primary goal in managing the disk array.
Page 104: Upgrading The Capacity Of A Fully-Loaded Disk Array
Concepts and Management Upgrading the Capacity of a Fully-Loaded Disk Array Upgrading the Capacity of a Fully-Loaded Disk Array It is easy to increase the capacity of your disk array, even if it is fully loaded with disk modules. By simply replacing the original disk modules with higher-capacity modules, you can add more logical drives or you can improve disk array performance by creating more unallocated capacity.
Page 105: Optimizing Performance
Concepts and Management Optimizing Performance Optimizing Performance Disk array performance is influenced by many factors, some host-related, some related to the configuration of the disk array itself. Host-related disk array performance issues can typically be identified and corrected using operating system utilities or third-party applications designed for this purpose. The following list identifies some of the factors that directly influence disk array performance.
Page 106: Controller Data Path
Concepts and Management Optimizing Performance Controller Data Path The data path through the controller is designed to transfer data between the disks and the host as efficiently as possible. However, under heavy I/O loads, bottlenecks may form in the data path. These bottlenecks can frequently be reduced by adding more hardware resources, such as cache RAM or disks.
Page 107: Performance Metrics
Concepts and Management Optimizing Performance Performance Metrics As shown in Table 4, the disk array uses an internal set of metrics to monitor its own performance. These metrics reflect internal events and conditions that are continually measured and stored by the disk array. A host disk array management utility can access the metrics and use them to evaluate performance, and even make recommendations on how to improve performance.
Page 108 Concepts and Management Optimizing Performance Disk Array Values: Performance Metric Typical/Limit Definition Disk Queue 2-4/>=10 (per disk) Indicates the average number of transactions on all disk drives waiting in the internal disk SCSI queues. Too many commands in the queues decrease performance.
Page 109: Rebuild Impact On Performance
Concepts and Management Optimizing Performance Rebuild Impact on Performance Because the rebuild process uses internal array resources, it may decrease array performance while a rebuild is in progress. This is particularly true if the host is issuing many I/Os to the disk array. The disk array uses a rebuild priority that allows you to determine which is more important: system performance or data redundancy.
Page 110: Increasing The Amount Of Raid 0/1 Space Available
Concepts and Management Optimizing Performance Increasing the Amount of RAID 0/1 Space Available CAUTION! Deleting a logical drive (LUN) destroys all data on the logical drive. Before deleting a logical drive, make backup copies of the files you want to save or move the files to another logical drive.
Page 111: Deleting A Logical Drive To Increase Raid 0/1 Space
Concepts and Management Optimizing Performance Deleting a Logical Drive to Increase RAID 0/1 Space Unlike deleting files from the operating system level, deleting a logical drive does free up capacity for use as RAID 0/1 space. To understand how file space is allocated, you must differentiate between file system free space and free space (or unallocated capacity) within the disk array.

Page 115: Replacing Modules
Troubleshooting Replacing Modules Replacing Modules If any module has a fault, you should acquire a replacement module before removing the failed module and install a replacement module. Since the modules are hot pluggable, they can be replaced even when the array is online with the host.

Page 117 Troubleshooting Replacing Modules CAUTION! To maintain proper cooling within the disk array, a failed fan module must remain in the fan slot until a replacement fan module can be installed. A missing fan module will cause a “power off pending” error, since eventually the loss of cooling air could cause the disk modules to overheat.

Page 252: Troubleshooting
Appendix D. Back-to-Back Racking Troubleshooting Troubleshooting A computer/instrument rack which has been field-upgraded for back-to-back racking has improved cooling and power features. In addition, the upgrade (the exhaust fan assembly) provides circuitry which can report fan failures and provide an indication of power failures. Fan and power failures are reported via indicator LEDs on the front of the fan assembly.
Page 253: Indicator Leds
Appendix D. Back-to-Back Racking Troubleshooting Indicator LEDs The exhaust fan assembly has four indicator LEDs located at the top front of the rack. The LEDs show the condition of the exhaust fan assembly and power to the fan assembly. Figure 54. Rack Indicator LEDs LED 1 Green PDU 1 and PDU 1 fans normal...
Page 254: Indicator Led States
Appendix D. Back-to-Back Racking Troubleshooting Indicator LED States This is the rack’s normal operating state. Power is being delivered from both Both green LEDs lit PDUs and to all the fans. Fans should be running normally. One or two of the three fans are not operating, probably due to a physical failure. One amber LED lit Two or three fans have failed.
Page 255: Problem Resolution
Appendix D. Back-to-Back Racking Problem Resolution Problem Resolution No LEDs lit All power to the fan assembly has failed. This is an indication the two of the PDUs and possibly the third are not supplying power to the arrays, thus indicating that none of the array enclosures are operating. This could be caused by a general power failure at the site, tripped circuit breakers for the circuits delivering power to the rack, or unplugged power cables.
Page 256: One Bank Of Leds Not Lit
Appendix D. Back-to-Back Racking Problem Resolution One bank of LEDs not lit When one bank of LEDs is not lit (no green and no amber), power to one of the PDUs has failed. One or two of the cooling fans are not spinning. The remaining two PDUs are likely to be providing power to the arrays.
Page 257: Removal And Replacement
Appendix D. Back-to-Back Racking Removal and Replacement Removal and Replacement The exhaust fan assembly can be removed and replaced without powering down the rack. The replacement part number for the exhaust fan assembly is E7687- 63001. WARNING!

Page 259: Frequently-Asked Questions
What replacement parts are there? The only replacement part is the exhaust fan assembly (part number E7687-63001). A failed exhaust fan assembly must be replaced by the Hewlett-Packard service provider. How rapidly must I replace a failed exhaust fan assembly? One failed fan in an exhaust fan assembly will not cause a critical cooling condition immediately.

™ ™ AutoRAID Array Technology AutoRAID is a trademark of Hewlett-Packard Company for the disk ™ array product. HP AutoRAID implements RAID technology automatically, without requiring you to know all the complexities of determining and setting up different RAID modes.
Page 262 Glossary Auto Rebuild Auto Rebuild begins immediately if a disk failure occurs, as long as enough space is available to perform the rebuild. No operator intervention is required to perform an Auto Rebuild. Once the Auto Rebuild has completed, the disk array is once again Fault-tolerant, since all user data is once again redundant.
Page 263 Glossary Data Redundancy Capacity Data Redundancy Capacity is the capacity required to support the RAID 0/1 and RAID 5 storage techniques used by the disk array for Data Redundancy. This capacity is managed by the Disk Array Controller and cannot be altered or reduced. Data Transfer Rate The Data Transfer Rate is the speed at which data is transferred between a host computer system and a peripheral.
Page 264 Glossary In either RAID 0/1 or RAID 5 mode, the data is stored with Data Redundancy, so that at any time, a single disk failure will cause no loss of user data and no interruption of data transfer. While Logical Drive space is defined and thus fixed, the available amount of free space can vary, because Dynamic Data Migration is able to switch user data from RAID 0/1 to RAID 5 mode as the Disk Modules become full.
Page 265 Glossary I/O Operation An Input/Output (I/O) Operation is an operation initiated by a host computer system during which data is either written to or read from a peripheral. Including A Disk The process of adding a Disk Module to the array configuration is called Including A Disk.
Page 266 Glossary Maximum Environmental Limit The maximum limit of temperature, humidity, vibration, shock, and altitude, which should not be exceeded during operation of an the product. See Recommended Operating Range. Migration Migration is the movement of data between one RAID mode and another RAID mode.
Page 267 Glossary RAID RAID stands for “Redundant Array of Independent Disks.” The disk array implements this technology to connect several disk drives to one Disk Array Controller. Several different forms of RAID implementations have been defined. The RAID implementations supported by the disk array include RAID 0/1 and RAID 5. RAID 0/1 RAID 0/1 is a disk array operating mode that provides high performance, but is somewhat inefficient in its use of disk space.
Page 268 Glossary Reload Traditionally, RAID systems required the entire user data set to be rewritten in order to add more capacity or adjust the RAID mode. The disk array does not require a Reload to make use of additional disk space because of the automatic Balancing and Dynamic Data ™...
Page 269 Glossary Secondary Array Controller In disk arrays with two controllers, one controller is called the Primary Array Controller and the other is called the Secondary Array Controller. The Secondary Array Controller offers redundant controller operation should the primary array controller ever fail. The Secondary Array Controller offers redundant controller operation (full access to all data) and it also monitors the status of the Primary Array Controller.
Page 270 Glossary Target A SCSI device (usually the peripheral) that responds to an operation requested by a SCSI initiator (usually the host system). SCSI peripherals are targets, but for some commands (for example, a COPY command), the peripheral may need to act temporarily as an initiator. Terminator Block An electrical connection at each end of the SCSI bus composed of a set of resistors (or possibly other components).
Page 271 Glossary WDTR WDTR (Wide Data Transfer Request) controls whether or not the additional eight bits on a wide bus will be utilized in most data phases of a SCSI command. WDTR also determines the negotiation protocol of the host. If WDTR is enabled, (default) the disk array will initiate for negotiation for wide transfer.
