About this guide
1 Enterprise Virtual Array description This chapter provides an overview of Enterprise Virtual Array and its components. Introduction to the Enterprise Virtual Array The HP StorageWorks Enterprise Virtual Array family is a high performance, scaled capacity, on demand, "virtual" RAID storage system. This storage system is designed for environments where improved storage use and scalability is critical.
• Dual– and multi–node cluster support provided for host–level fault tolerance and high system availability. • Support for active-active failover, allowing the use of industry popular multipathing solutions and native host bus adapters. Performance Outstanding self-tuning performance includes: • Virtualization technology—Vraid, enables data to be distributed from 8 to 240 disks to increase disk spindle count far beyond traditional RAID sets.
For the most current information on supported operating systems, see the appropriate connectivity documents. See “Related documentation” on page 13 for links to these documents. Fault management and diagnostics WEBES must be installed to ensure proper customer alerts for their EVA products. WEBES can be used as part of the HP ISEE remote service offering.
• Configure and monitor physical subsystem components such as controllers, physical disks, power supplies, blowers, and network connections. • Configure and view controller logs and events. Controller software HP StorageWorks Virtual Controller Software (VCS) manages all aspects of storage system operation. VCS provides scalable capacity on-demand, improves performance, increases disk utilization efficiency, and allows for easy dynamic storage expansion.
• HSV controller—Manages all aspects of storage system operation, including communications between host systems and other devices. A pair of HSV controllers is included in Enterprise Virtual Array. • Rack—A variety of free-standing racks are available. Physical layout of the storage system The basic physical components are shown in Figure 1. The disk drives are installed in the disk enclosures, which connect to Fibre Channel (FC) loop switches. The controller pair also connects to the FC loop switches.
Fibre Channel loop switches The Fibre Channel loop switch acts as a central point of interconnection and establishes a fault-tolerant physical loop topology between the controllers and the disk enclosures. The EVA5000 uses four loop switches to connect the drive enclosures to the controller pair. The FC loop switches provide the following features. For detailed information on Fibre Channel loop switches, see Fibre Channel loop switches. • • • • • 2.

Entering the WWN Fibre Channel protocol requires that each controller pair have a unique WWN. This 16-character alphanumeric name identifies the controller pair on the storage system. Two WWN labels attached to the rack identify the storage system WWN and checksum. See Figure 4. NOTE: • The WWN is unique to a controller pair and cannot be used for any other controller pair or device anywhere on the network.
NOTE: If you enter an incorrect WWN or checksum, the system will reject the data and you must repeat the procedure. Entering the storage system password The eight-character storage system password feature enables you to restrict management access to the storage system. Table 3 describes the push button functions when using the password feature. Table 3 System password push button functions Button Function Selects a password character by scrolling up through the character list one character at a time.

Storage system shutdown and powerup The storage system is shut down using HP Command View EVA. The shutdown process performs the following functions in the indicated order: 1. 2. 3. 4. 5. Flushes cache Removes power from the controllers Disables cache battery power Removes power from the drive enclosures Disconnects the system from HP Command View EVA NOTE: The storage system may take a long time to complete the necessary cache flush during controller shutdown when snapshots are being used.
3. Power on the circuit breakers on both EVA rack PDUs. Verify that all drive enclosures are operating properly. The status indicator and the power indicator should be on (green). 4. Wait three minutes and then verify that all disk drives are ready. The drive ready indicator and the drive online indicator should be on (green). 5. Power on the upper controller. It takes the roll of master controller. 6. Wait 10 seconds and then power on the lower controller. It takes the roll of slave controller. 7.
NOTE: If the storage system contains disk drives of different capacities, the SSSU procedures used do not guarantee that disk drives of the same capacity will be exclusively added to the same disk group. If you need to restore an array configuration that contains disks of different sizes and types, you must manually recreate these disk groups. The controller software and the utility’s CAPTURE CONFIGURATION command are not designed to automatically restore this type of configuration.
• The disk drives should be distributed evenly across the disk enclosures. The number of disks of a given type in each enclosure should not differ by more than one. For example, no enclosure should have seven disks until all the other enclosures have at least six. A minimum of four disks are required to be populated in every disk enclosure. • Disk drives should be installed in vertical columns within the disk enclosures. Add drives vertically in multiples of eight, completely filling columns if possible.

On On On • Top port—Fibre Channel drive enclosure signal detected. • Power—Present. • Bottom port—Fibre Channel drive enclosure signal detected.
Fibre Optic Fibre Channel cables The Enterprise Virtual Array uses orange, 50-µm, multi-mode, fiber optic cables for connection to the SAN. The fiber optic cable assembly consists of two, 2–m fiber optic strands and small form-factor connectors on each end. See Figure 13. To ensure optimum operation, the fiber optic cable components require protection from contamination and mechanical hazards. Failure to provide this protection can cause degraded operation.
• Both online high-performance disk drives and FATA disk drives in a variety of capacities and spindle speeds. • Better vibration damping for improved performance. Up to 14 disk drives can be installed in a drive enclosure. Disk drive status indicators Three status indicators display the drive operational status. Figure 15 shows the disk drive status indicators. Table 9 provides a description of each status indicator. Figure 15 Disk drive status indicators 1. Activity 2. Online 3.

NOTE: An error always generates a condition report. Not all condition reports are generated by errors. Error condition categories Each error condition is assigned to a category based on its impact on disk enclosure operation. The following four error categories are used: • Unrecoverable—the most severe error condition, it occurs when one or more enclosure components have failed and have disabled some enclosure functions.
Correcting the error removes the associated condition from the error queue. Replacing the EMU will also clear the error conditions. The order in which the EMU displays the error queue information is based on two factors: • The severity of the error • The time the error occurred The most severe error in the queue always has precedence, regardless of how long less severe errors have been in the queue. This ensures that the most severe errors are displayed immediately.

Replacing the failed component CAUTION: Components can be damaged by electrostatic discharge. Observe the following proper anti-static protection: • Always transport and store CRUs in an ESD protective enclosure. • Do not remove the CRU from the ESD protective enclosure until you are ready to install it. • Always use ESD precautions, such as a wrist strap, heel straps on conductive flooring, and an ESD protective smock when handling ESD sensitive equipment.
Types of disk failures There are two types of disk failures: • Hard failure: The disk is no longer functioning properly and has been assigned a failed status. This type of failure is indicated by an operational state of Failed in HP Command View EVA. The amber fault status indicator on the disk is typically on. • Impending failure: Although the disk is still functioning, errors have been detected that indicate an impending failure. This type of failure is not accompanied by a failed status.
Figure 32 Selecting a storage system Figure 33 Checking redundancy Verifying component failure Before replacing a disk, use the following methods to verify component failure: CAUTION: If HP Command View EVA does not present a status consistent with the disk status indicators, or if HP Command View EVA or your system monitoring tool indicates multiple hardware failures, contact HP support for assistance (http://www.hp.com/support). • Analyze any failure messages received.
3. Check the disk Node World Wide Name against the error message UUID information recorded earlier to ensure you have selected the correct disk (Figure 35). 4. Check the disk operational state. If a hard failure has occurred, the operational state should be Failed. A disk with an impending failure indicates Good status until the condition of the disk degrades enough to become a hard failure. 5. Verify that the Requested usage and Actual usage fields display Ungrouped (Figure 37).
NOTE: Certain hard disk failures result in a status of Drive unmated. If you are running XCS 5.xxx or earlier and HP Command View EVA 5.x or earlier, the Drive unmated status disables the Remove button. In this situation, you can remove the disk immediately from the enclosure. The fault indicator will be on to help locate the failed disk. 1 2 3 Figure 34 Disk status indicators 1. Activity 2.
Figure 37 Checking disk group status Removing a disk CAUTION: Rotating media can make the disk difficult to handle. To avoid dropping and damaging the disk, wait approximately 30 seconds for the media to stop rotating before removing the disk from the enclosure. 1. Push in the wine-colored ejector button (1) and pull the release lever (2) down to the full open position. 2. Pull the disk part way out of the enclosure (3) and wait for the media to stop spinning. 3.
NOTE: To return the Device Addition Policy to automatic, repeat this procedure after you verify that the disk has the correct firmware version. Installing a disk CAUTION: You should only replace one disk at a time. After installing the new disk, complete the remaining procedures in this document for this disk before you attempt to replace another disk. 1. 2. 3. 4. Push in the ejector button on the disk and pull the release lever down to the full open position.
http://www.hp.com/support/manuals Click Disk Storage Systems under Storage, and then select the appropriate product under EVA Disk Arrays. If the disk is running an unsupported version of firmware, download the correct firmware from the following website and install it using the instructions included with the firmware file. Do not add the disk to a disk group if it is running an unsupported firmware version. http://www.hp.
NOTE: Because this component is used in several products, the drawings may reflect a different enclosure than the one you have. The removal and replacement procedure is the same for each product. Before you begin Observe the following precautions when replacing the power supply/blower. CAUTION: You have only seven minutes to perform the replacement procedure! Both power supplies must be installed for the enclosure to cool properly.

The American National Standards Institute’s (ANSI) document that specifies arbitrated loop topology operation. FC HBA Fibre Channel Host Bus Adapter. An interchangeable term for Fibre Channel adapter. See also FCA. FCA Fibre Channel Adapter. An adapter used to connect the host server to the fabric. Also called a Host Bus Adapter (HBA) or a Fibre Channel Host Bus Adapter (FC HBA). See also FC HBA.
Gb Gigabit. A measurement of the rate at which the transfer of bits of data occurs. Sometimes referred to as Gbps. Nominally, a Gb is a transfer rate of 1,000,000,000 (109) bits per second. For Fibre Channel transceivers or FC loops the Gb transfer rates are: • 1 Gb is a transmission rate of 1,062,500,000 bits per second. • 2 Gb is a transmission rate of 2,125,000,000 bits per second. GB Gigabyte. A unit of measurement defining either: • A data transfer rate.
I/O module Input/Output module. The enclosure element that is the Fibre Channel drive enclosure interface to the host or controller. I/O modules are bus speed specific, either 1 Gb or 2 Gb. IDX A 2-digit decimal number portion of the HSV controller termination code display that defines one of 32 locations in the Termination Code array that contains information about a specific event. See also param and TC.
logon Also called login, it is a procedure whereby a user or network connection is identified as being an authorized network user or participant. loop See arbitrated loop. loop ID Seven-bit values numbered contiguously from 0 to 126 decimal and represent the 127 valid AL_PA values on a loop (not all 256 hexadecimal values are allowed as AL_PA values per Fibre Channel). loop pair A Fibre Channel attachment between a controller and physical disk drives.
multi-mode fiber A fiber optic cable with a diameter large enough (50 microns or more) to allow multiple streams of light to travel different paths from the transmitter to the receiver. This transmission mode enables bidirectional transmissions. Network Storage Controller See NSC. NONCRITICAL Condition A drive enclosure EMU condition report that occurs when one or more elements inside the enclosure have failed or are operating outside of their specifications.
PDU Power Distribution Unit. The rack device that distributes conditioned AC or DC power within a rack. petabyte A unit of storage capacity that is the equivalent of 250, 1,125,899,906,842,624 bytes or 1,024 terabytes. physical disk A disk drive mounted in a drive enclosure that communicates with a controller pair through the device-side Fibre Channel loops. A physical disk is hardware with embedded software, as opposed to a virtual disk, which is constructed by the controllers.
read ahead caching A cache management method used to decrease the subsystem response time to a read request by allowing the controller to satisfy the request from the cache memory rather than from the disk drives. reconstruction The process of regenerating the contents of a failed member data. The reconstruction process writes the data to a spare set disk and incorporates the spare set disk into the mirrorset, striped mirrorset or RAID set from which the failed member came. redundancy 1.
small computer system interface See SCSI. Snapclone A virtual disk that can be manipulated while the data is being copied. Only an Active member of a virtual disk family can be snapcloned. The Snapclone, like a snapshot, reflects the contents of the source virtual disk at a particular point in time. Unlike the snapshot, the Snapclone is an actual clone of the source virtual disk and immediately becomes an independent Active member of its own virtual disk family.
may be incapable of recovering or bypassing the failure and will require repairs to correct the condition. This is the highest level condition and has precedence over all other errors and requires immediate corrective action. unwritten cached data Also called unflushed data. See also dirty data. UPS Uninterruptible Power Supply. A battery-operated power supply guaranteed to provide power to an electrical device in the event of an unexpected interruption to the primary power supply.
write back caching A controller process that notifies the host that the write operation is complete when the data is written to the cache. This occurs before transferring the data to the disk. Write back caching improves response time since the write operation completes as soon as the data reaches the cache. As soon as possible after caching the data, the controller then writes the data to the disk drives.
