Array Controller The array controller contains the intelligence and functionality required to manage the operation of the array. Its functions include: ■ Implementing HP AutoRAID™ technology to ensure optimum performance and cost-efficient data storage. ■ Managing all communication between the host and the disk drives via one (single array controller) or two (dual array controller) Fibre Channel arbitrated loops. ■ Maintaining data integrity. ■ Rebuilding the array in the event of a disk failure.
DIMMs Note The DIMMs are a critical component in maintaining correct operation of the array. Use extreme caution when replacing or modifying the DIMM configuration. Table 25 on page 136 shows the valid configuration of DIMMs for each controller cache size. In a dual controller configuration, both controllers must have the same cache size.
power-on self-test, the self-test will halt until the battery is charged to a minimum operating level. Battery Life. Many factors affect battery life, including length of storage time, length of operating time, storage temperature, and operating temperature. A battery should be replaced if the BATTERY LEDs or the software indicate a battery has diminished storage capacity. GBIC (VA 7100 Only) A Gigabit Interface Converter (GBIC) is connected to the HOST FC connector on the VA 7100 array controller card.
A label on the disk drive provides the following information: — Capacity in gigabytes: 18G, 36G, 73G, or 146G — Interface: FC (Fibre Channel) — Rotational speed in revolutions per minute: 10K or 15K Note A red zero (0) on the capacity label distinguishes a disk drive filler panel from a disk drive. Image Disks When the array is formatted, the array controller selects two disks as image disks. On the VA 7410 a third disk is identified as a backup in the event one of the primary image disks fails.
If an image disk fails on the VA 7100 or VA 7400, the array will operate with a single image disk until the failed disk is replaced. If an image disk fails on the VA 7410, the backup image disk will be used, maintaining image disk redundancy. When the original failed image disk is replaced, it will be assigned the role of backup image disk. Disk Drive Filler Panels Disk drive filler panels are used in both the controller and disk enclosures to fill empty slots in place of disk drives.
Product Overview Disk Enclosure Components Figure 7 shows the front and rear panel components of the disk enclosure connected to the VA 7400/7410 controller enclosure. Both DS 2400 and DS 2405 Disk Systems are used as disk enclosures on the VA 7400/7410.

Link Controller Card (VA 7110/7400/7410 Only) The link controller card (LCC) functions as a fiber optic transceiver for the disk enclosure. It allows up to six disk enclosures to be connected to the controller enclosure. Each LCC includes a Fibre Channel address switch, used to set the Fibre Channel loop address of the card. Each disk enclosure must have a unique address and both LCCs in a disk enclosure must be set to the same address.

Power Modules The disk enclosure is shipped with two fully redundant power modules. Each power module contains: ■ An autoranging power supply that converts ac input power to dc output power for use by the other array components. The power supplies share the power load under non-fault conditions. If one power supply fails, the other supply delivers the entire load to maintain power for the array. Each power supply uses a separate power cord.
When the power/standby switch is in the “power” position, ac power is applied to the primary and secondary sides of the power supplies in the power module and all of the dc circuits in the array are active. When the power/ standby switch is in the “standby” position, ac power is only applied to the primary side of the power supplies; all of the dc circuits in the array are disabled. To switch power on, push in the power/standby switch to the “power” position. See Figure 11.
Power-On Self-Test Immediately after the array is powered on, the controller enclosure and disk enclosures (VA 7400/7410 only) perform a power-on self-test. During a power-on self-test, you will see the following front panel activity: ■ The system power/activity LED turns on solid green.
Note If the power fails or if you unplug the power cords without performing a shutdown, the following sequence will occur when the array is powered on again: 1 The array will attempt to retrieve the maps from cache and determine if they are valid. 2 If the maps are not valid, the array will retrieve the maps from the image disks.
Data Storage Process Virtual Array The term “Virtual Array” refers to the way the array manages the disks as a pool of data storage blocks instead of whole physical disks. Like other virtualization within computer systems, this virtualization greatly simplifies the management of the array. Internally, the array uses sophisticated data structures to manage the logical-to-physical address translation. These data structures, often referred to as the “maps”, are key to the operation of the array. See Figure 12.
Figure 12 Virtual Data Storage Product Overview Cache Maps Storage Pool LUN 1 Host LUN 2 Redundancy Groups Array physical capacity is divided into Redundancy Groups. A Redundancy Group (RG) can be thought of as an independent array. Each RG has its own set of disks, active hot spare, and controller. LUNs are created from capacity within a single RG. LUNs can be accessed simultaneously through either controller. Multiple redundancy groups provide the following benefits: ■ Fault isolation.
high-performance disks, and the other RG from large, slower, highcapacity disks. The VA 7100 and VA 7400/7410 differ in their implementation of redundancy groups. VA 7100/7110 Redundancy Group The VA 7100 and VA 7110 each have one redundancy group (RG1). See Figure 13 and Figure 14. All the disks in the array belong to RG1. LUNs created from RG1 are available through both controllers (in a dual controller configuration). There are two internal fibre channel loops, one from each controller.

VA 7400/7410 Redundancy Groups The VA 7400 and VA 7410 have two redundancy groups (RG1 and RG2). See Figure 15 and Figure 16. ■ Controller 1 manages Redundancy Group 1 (RG1), which consists of all disks in odd numbered slots (D1, D3, D5, D7, D9, D11, D13, D15) in the controller enclosure, and in all disk enclosures (JA0-JA5).

Performance Path Because the array has two active controllers, the host will typically have two paths to data, as shown in Figure 17. ■ The primary path is through the controller which owns the LUN being accessed. That is, the controller that manages the RG the LUN belongs to. On the VA 7400 and 7410 each LUN is assigned to RG1 or RG2, managed by controller 1 and controller 2 respectively. When accessing data on a LUN, the host should send I/Os to the controller which owns the LUN.
VA 7400/7410 Performance Path The following example illustrates how the performance path is used in a VA 7400/7410: Assume LUN 4 is part of Redundancy Group 2 under Controller 2. An HP-UX host has two device files that have two separate paths to LUN 4: The primary device file that addresses Controller 2, and the secondary device file that addresses Controller 1. The performance path uses the primary device file, because Controller 2 owns LUN 2. The non-performance path uses the secondary device file.
RAID Levels The virtual array can be operated in RAID 1+0 level or AutoRAID level, which is a combination of RAID 1+0 and RAID 5DP. The RAID level selected is influenced by factors such as capacity demands and performance requirements. Once a RAID level is selected, it is used for the entire array. Changing the RAID Level of the Array The RAID level for the array is established during installation. It is possible to change the RAID level after installation.
Upon completion of the rebuild of a failed disk, the array is once again protected against any single disk failure. Note RAID groups with an even number of disks will always have a single adjacent disk after a disk failure, and RAID groups with an odd number of disks will always have two adjacent disks after a disks failure. The segment size for a Virtual Array is always 256 Kbytes.
Product Overview simultaneous disk failures. The two redundancy segments are referred to as “P” and “Q” parity. P, like traditional RAID 5 arrays, uses an XOR (parity) algorithm. P parity is based on Reed-Solomon ECC technology, similar to error detection and correction found in ECC DRAM. Application data, and the P and Q parity data, rotate to different disks for each stripe in a RAID Group. Like RAID 1+0, this effectively eliminates hot spots.
Figure 19 RAID 5DP Data Storage Example Data Availability and AutoRAID When configured in the AutoRAID mode, the Virtual Array uses a combination of RAID 1+0 and RAID 5DP. As a result, the disks within a single RG can have a portion of its data capacity used as RAID 1+0, while the other portion is used as RAID 5DP. During disk failures, rebuild is directed to rebuild the most statistically vulnerable data first. After the first disk failure in an RG, the rebuild process prioritizes RAID 1+0 data first.
continuous high demand from the host will preempt all data migration activities. The controller is programmed to manage cluster placement. It uses well-known logic, or rules, about RAID level performance characteristics and storage efficiency. This logic directs data that is frequently modified by small transactions to RAID 1+0 storage. Data that is infrequently written, or data that is written sequentially, is directed to RAID 5DP storage.
Data I/O Architecture The internal architecture of the array controllers is designed to optimize the speed of data transfer between the array and the host. The internal architecture for each product is illustrated in Figures 20, 22, and 23. The following major components are involved in the flow of data through the array: ■ Data flow processor - manages movement of data over the internal high- speed busses. The processor also manages the flow of data into and out of the ECC cache.

Product Overview Operating Tips The following information will help you understand some of the operating features of the array and may help you manage the array efficiently. Automatic Hot Spare Setting Behavior The following behavior only occurs on a VA 7400/7410 operating in AutoRAID mode, and with the hot spare mode set to Automatic. To avoid this behavior, you may want to set the hot spare mode to a setting other than Automatic.
possibility of data loss in the event of multiple disk failures. Although the statistical advantage of this minimal but measurable, HP advises when ever possible to keep an even number of disks in each redundancy group. For optimum availability, it is recommended that you have an even number of disks in each redundancy group. Because of the manner in which the array stores data, an even number of disks reduces the possibility of data loss in the event of multiple disk failures.

3 Troubleshooting This chapter describes how to troubleshoot the array if a failure occurs. A failure may be indicated by any of the following: ■ array status LEDs ■ array management software ■ host applications This chapter will only discuss the first two indicators. Refer to your host application documentation for host application failure indications.
Troubleshooting Steps Follow these basic steps for troubleshooting the array: 1 Check the state of the array and the status of the field replaceable units (FRUs) in the array. See "Array State & Status" on page 76. 2 Check the array controller logs. See "Checking Array Controller Logs" on page 87. 3 Replace any faulty FRU or repair the array. 4 Verify the array is operational and that no amber fault LEDs, error messages, or Warning states are displayed.
Redundant FRUs The following FRUs are redundant.
Array State & Status The state of the array is indicated by CommandView SDM software with the following state parameters (state messages in parenthesis): ■ Array Controller (Controller Mismatch, Mismatched Code, No Code, No Map) ■ Disk Drives (Disk Format Mismatch, No Quorum, Not Enough Drives) ■ Array Readiness (Ready, Shutdown, Shutdown Warning, Shutting Down, Starting Up) ■ Array Warnings (Active Spare Unavailable, Battery Failure, Code Mismatch, Controller Mismatch, Controller Problem, Data Unavail
A Link Down warning state can be reported by the CVGUI if either of the following two failures occur: ■ If a host Fibre Channel loop fails due to the failure of a host HBA, a faulty or disconnected fiber cable, a faulty GBIC (VA 7100 only), or the failure of a data flow component on an array controller. ■ If an array Fibre Channel loop fails due to a port failure on a disk drive, faulty loop circuitry on the midplane, or the failure of a data flow component on an array controller.
LED Status Indications If a component fails in an enclosure, the fault will be indicated by at least two amber fault LEDs. For example, if a disk drive fails, the system fault LED will light and the disk drive fault LED will light. The status LEDs for the various hardware assemblies are shown in Figure 24 through Figure 31. The status indications are described in the accompanying tables.

Click on “Array Status” and view the “Overall Array State” and “Warning States”. Click the Help button for a description of the problem and solution for “Warning States”.
Array Controller Logs Types of Array Controller Logs There are two types of array controller logs: ■ Controller logs. Controller logs contain events relating to the operation of all FRUs in the array, obtained from the controller during the operation of the array. The CommandView SDM logging routine polls the array every 15 minutes to retrieve and store the log entries in special controller log files. Each log entry has a decimal event number and an event name.
Checking Array Controller Logs Check the array controller logs using one of the following methods: ■ CommandView SDM Command Line User Interface (CLUI). Refer to the armlog command in the HP CommandView SDM Installation & User Guide. ■ CommandView SDM CommandView User Interface (CVUI).
EMS Hardware Monitors (HP-UX Only) With Event Monitoring Service (EMS) you can be alerted to problems as they occur, allowing you to respond quickly to correct a problem before it impacts the operation of the array. All operational aspects of the array are monitored. EMS gives you the flexibility to deliver event notification using a variety of methods. EMS is enabled automatically during installation of the CommandView SDM software, ensuring immediate detection and reporting of array events.
use of the disk system can continue. The problem can be repaired at a convenient time. ■ Information - An event that is expected as part of the normal operation of the hardware. No action is required. EMS Event Message An EMS event message typically includes the following information: ■ Message Data - Date and time the message was sent, the source and destination of the message, and the severity level.

Hot Swappable FRUs A field replaceable unit (FRU) is “hot swappable” if it can be removed and replaced while the array is powered on, without disrupting I/O activity. A FRU is not hot swappable if all applications and file systems must be terminated, or a host shutdown must be performed, before it can be replaced. Table 22 shows hot swappable FRUs for the controller enclosure and the disk enclosure.
Controller Enclosure Removal & Installation Procedures Disk Drives The following procedure is used for disks in both the controller enclosure and the disk enclosure. Removing a Disk Drive Caution Do not operate the array for more than 5 minutes with a disk drive or filler panel removed. Either a disk drive or filler panel must be installed in the slot to maintain proper airflow. 1 Push down the release tab (Figure 34, 1) and pull up the cam lever (2).

Caution The array controller can be damaged by electrostatic discharge. Use the ESD kit provided when removing and installing an array controller. To prevent data loss, it is recommended that a full backup be performed before removing an array controller. Do not operate the array for more than 5 minutes with an array controller or filler panel removed. Either an array controller or filler panel must be installed to maintain proper airflow in the controller enclosure.
If a DIMM failure did not occur: a Remove the battery from the removed array controller. See "Removing an Array Controller Battery" on page 117. b Remove the DIMMs from the removed array controller. See "Removing an Array Controller DIMM" on page 120. Installing an Array Controller (HP Service Personnel Only) Caution If the green BATTERY LED is flashing and you remove a DIMM, damage to the array controller or DIMM may occur.
8 VA 7110/7400/7410 only: Tighten the cam lever screw (Figure 44, 1). 9 VA 7100 only: Replace the GBIC (Figure 39, 3). 10 Replace the fiber optic cables (see Figure 39 or Figure 40). Note If you need to change the default Fibre Channel Loop ID on the array controller, use the following VFP command: vfpmgr -L -c Note The following step is only required if an HP-UX host is connected to the array using one of the following FC HBAs: A5158A, A6684A, A6685A, or A6795A.
Replacing the Controller in a Single-Controller Array Replacing a controller in a single-controller array is complicated by the fact that there is not a second controller to clone the firmware and maps. In this situation there are two alternatives for recovering the firmware and maps. The procedure used is determined by the nature of the controller failure.

Array Controller DIMMs Removing an Array Controller DIMM (HP Service Personnel Only) Caution DIMMs can be damaged by electrostatic discharge. Use the ESD kit provided when removing and installing DIMMs. The following procedures are used when removing/installing DIMMs on a single controller. If you are upgrading the DIMMs on both controllers, you must shutdown the array. See "Upgrading Array Controller DIMMs" on page 135. 1 Remove the array controller card. See "Removing an Array Controller" on page 107.
replaced offline, power-on initialization will not complete if the DIMM memory in both array controllers does not match. 1 Insert the DIMM (Figure 48, 2) evenly into the DIMM slot. 2 Use your thumbs to apply even pressure to the top edge of the DIMM and push the DIMM firmly into the slot. The DIMM extraction levers (1) will automatically capture the DIMM. 3 Replace the battery. See "Installing an Array Controller Battery" on page 118. 4 Replace the array controller card.
Midplane Assembly Caution — To prevent data loss, it is recommended that a full backup be performed before removing a midplane assembly. — The midplane assembly can be damaged by electrostatic discharge. Use the ESD kit provided when removing and installing the midplane assembly. — The midplane assembly is tied directly to the enclosure. Once a midplane assembly has been installed in an enclosure, you cannot reuse it in another enclosure.
8 Using a flat-blade screwdriver, push up the two front top-cover side-clips (3) and pop the top cover up slightly. 9 Twist the screwdriver blade in the rear gaps (4) on the side of the chassis, directly behind the top cover. 10 Place a screwdriver blade in a vertical position in the slots (5) on top of the chassis directly behind the top cover. Hit the handle of the screwdriver with the palm of your hand until the top cover moves forward 3/16 inch (0.5 cm). 11 Slide the top cover (6) off the chassis.

Disk Enclosure Removal & Installation Procedures Disk Drives See "Disk Drives" on page 98 for information on removing and installing disk drives. Disk Drive Filler Panels See "Disk Drive Filler Panels" on page 100 for information on removing and installing disk drive filler panels. Power Modules Removing a Power Module Caution Do not operate the array for more than 2 minutes with a power module removed, or the array may automatically initiate a shutdown.
4 Tighten the cam lever screws (1) with a T-10 driver or flat-blade screwdriver. 5 Re-connect the power cord.
Link Controller Cards (LCCs) Caution The LCC can be damaged by electrostatic discharge. Use the ESD kit provided when removing and installing an LCC. The DS 2400 Disk System and the DS 2405 Disk System use different LCCs. Do not mix LCCs in the same disk enclosure. To prevent data loss, it is recommended that a full backup be performed before removing an LCC. Do not operate the disk enclosure for more than 5 minutes with an LCC removed.
2 Pull out both cam levers (Figure 53, 2). 3 Push the LCC (3) firmly into the slot. 4 Push in both cam levers at the same time. 5 Tighten the cam lever screw (1). 6 Replace the fiber optic cables (Figure 51, 1 and 2).

Figure 53 Setting the FC Loop Speed Switch Must be set to 1GB/s 130 Servicing & Upgrading
Midplane Assembly Note The controller enclosure and the disk enclosure both use the same midplane assemblies. To remove and replace a midplane assembly in the disk enclosure, follow the steps under "Removing a Midplane Assembly" on page 122 and "Installing a Midplane Assembly" on page 123, except in step 3, you will disengage (when removing) or re-engage (when installing) the LCCs. See "Removing an LCC" on page 127.
Upgrading the Array Increasing Storage Capacity Adding a New Disk Module A new disk drive may be added online to the controller and disk enclosures at any time to upgrade storage capacity in the array. See "Installing a Disk Drive" on page 98 to add a disk. If the Auto Include feature is enabled, the array controller will automatically include the new disk in the array. However, a new LUN must be created in order to make the new capacity available to the host.
the controller enclosure are on loop 1. Consequently, the number of disk enclosures on loop 1 should always be equal to or one less than the number of enclosures on loop 2. — If the disk enclosure being added is a DS 2405 Disk System, make sure the array controller firmware is HP14 or later. Earlier versions of controller firmware will not recognize the DS 2405, and may cause the array to generate a Phantom Enclosure warning state. 1 Install the new disk enclosure in the rack.
8 Reinstall one disk module in each redundancy group (one odd slot and one even slot) and wait until the disk format operation is complete and the disks come online. Use Command View to monitor the disk status. When the disks have come online, repeat this step for the next set of disks. Repeat until all disk modules have been installed. Note There is only one redundancy group on the VA 7110, so only one disk module at a time should be installed.
Upgrading Array Controller DIMMs (HP Service Personnel Only) The amount of controller cache can be increased by adding a second DIMM to each controller, or by replacing existing DIMMs with higher capacity DIMMs. Regardless of which strategy is used, both controllers must have the same DIMM configuration. Valid DIMM configurations are listed in Table 25. Before beginning the upgrade, make sure you have the required DIMMs. Caution Make sure you observe the following precautions.
5 Remove the battery from the controller. See "Removing an Array Controller Battery" on page 117. 6 Wait two minutes, and then add or replace the DIMMs. See "Installing an Array Controller DIMM" on page 120. 7 Reinstall the battery on the controller. See "Installing an Array Controller Battery" on page 118. 8 Reinstall the controller. See "Installing an Array Controller" on page 110. 9 Repeat steps 4 - 8 for the other controller. 10 Power on the array and wait for all components to become ready.
1 Backup any data on the array that you wish to keep. You may also want to record the LUN structure on the array. You will need to recreate it after formatting the array. 2 Perform the steps in "Upgrading Array Controller DIMMs" on page 135, removing or replacing DIMMs as required. The cache must be reduced on both controllers.. After powering on the array, continue with the following steps. 3 Check the status of the array. It should indicate No Maps. 4 Format the array using CommandView SDM or the VFP.
Only wrapped firmware files should be used when downloading LCC firmware. This will prevent downloading the wrong firmware to the LCC. Download new firmware to an LCC using HP CommandView SDM software. (See “Upgrading LCC Firmware” in the Help System.) Upgrading Disk Firmware (HP Service Personnel Only) Caution To prevent data loss, it is recommended that a full backup be performed before starting this procedure. Download new firmware to a disk drive using HP CommandView SDM software.
