Command View EVA Storage System Managed by Another Management Agent A management agent can control multiple storage systems and multiple management agents can also control a single storage system. However, only one agent is allowed to manage a storage system at a time. Password protection controls management agent access to storage systems.
Command View EVA Controlling and Monitoring Storage System Components This section discusses controlling and monitoring storage system components. The components controlled using Command View EVA are: ■ Virtual Disks ■ Hosts ■ Disk Groups ■ Data Replication Groups ■ Hardware All of these components are accessible using the folders in the Navigation pane, as shown in Figure 18.
Command View EVA Note: The maximum number of virtual disks is 512. One virtual disk can be presented to multiple hosts. The maximum size of a virtual disk is 2047 GB. The maximum number of presentations is 8192. There are three types of virtual disks: ■ Active member of a virtual disk family—a virtual disk that is accessed by one or more hosts for storage. An active member of a virtual disk family is automatically created whenever a new virtual disk family is created.
Command View EVA Figure 19: Virtual Disk folder Presenting a Host A host can be selected for presentation (that is, a virtual disk made available to a host). Two choices exist: ■ Select a host for presentation—indicates that the host can use the virtual disk for data storage. The host will see the virtual disk at the next available LUN. ■ Select a host and LUN for presentation—indicates that the host can use this virtual disk for data storage. The host will see the virtual disk at the specified LUN.
Command View EVA Figure 20: Host folder Properties of individual hosts are accessed by selecting a specific host within the hosts folder. Selecting a host displays the Host Properties window, as shown in Figure 21.
Command View EVA Adding a Host Before a host can use the storage system's virtual disks, the host must be known to the storage system. This process is called “adding a host.” Adding a host creates a path from the storage system to one host FCA port. Additional host FCA ports can be specified as a modification to the host properties. Deleting a Host Deleting a host removes it from the list of hosts that the storage system maintains. You cannot delete a host if there are any virtual disks presented to it.
Command View EVA Disk Groups A disk group is the set or pool of physical disk drives in which a virtual disk is created. The physical disk is a disk drive that plugs into a drive bay and communicates to the controllers through the device-side Fibre Channel loops. Only the controllers can communicate directly with the physical disks. Collectively, the physical disks are called the array and constitute the storage pool from which the controllers create virtual disks.
Command View EVA Selecting a disk group within the disk groups folder in the Navigation pane displays the Disk Group Properties page, as shown in Figure 23. Figure 23: Disk Group Properties page Working with Disk Groups The following operations can be performed on a disk group: 66 ■ Creating a disk group—combines physical disk drives into one disk group. The system automatically selects drives based on their physical locations.
Command View EVA ■ Locating a disk group—causes an LED to light up allowing you to identify the physical drives that make up the disk group. ■ Ungrouping a disk—removes a disk from a disk group. Note: The disk is not deleted from the disk group but is actually ungrouped. If the disk is to be removed from the rack, use the locate function so that it can be physically identified in the rack before it is ungrouped. You cannot delete the only disk group (such as the default disk group).
Command View EVA Figure 24: Data Replication folder Hardware The hardware folders provide a view into the operation of various physical components of the storage system: ■ Rack—a floor-standing structure primarily designed for, and capable of, holding and supporting storage system equipment. ■ Controller—a hardware and firmware device that manages communications between host systems and other devices.
Command View EVA The Hardware folder is accessible using the folder structure in the Navigation pane, as shown in Figure 25. Figure 25: Hardware folder Racks The rack container is located within the Hardware folder and is accessible using the folder structure in the Navigation pane, as shown in Figure 26. Each container displays the objects located in that rack. One rack container exists for each rack connected to the storage environment.
Command View EVA For more information about racks, see “Storage System Racks” on page 128. Controllers Each storage system has a pair of controllers. The controller properties can be viewed by expanding the controller enclosure icon, then selecting the desired controller. The following properties are available for each controller: ■ General—identifies the general properties of the controller. These properties include identification, condition and state, cache memory, and location information.
Command View EVA Figure 27: Controller folder For more information about controllers, see “HSV100 Controllers” on page 111. Enclosures Two types of hardware enclosures exist for the Enterprise Virtual Array, disk enclosures and controller enclosures. ■ Disk enclosure—a disk enclosure contains up to 14 physical disk drives and their supporting structures. Each of the vertical positions in the enclosure where the disk drive is located is called a bay.
Command View EVA ■ Controller enclosure—a controller enclosure is the mechanical enclosure that protects the controller circuit board and its associated components for a controller pair. Except for the cache batteries and blower assemblies, all components in the controller enclosure are considered one assembly and must not be separated. The disk enclosure object is accessible using the folder structure in the Navigation pane, as shown in Figure 28.

Storage System Hardware Components 4 This chapter describes the HP StorageWorks Enterprise Virtual Array 3000 hardware components.
Storage System Hardware Components Fibre Channel Drive Enclosures The major enclosure components are: ■ 2.125-Gb, dual loop, 14-drive enclosure. ■ Dual-loop, FC-AL I/O modules and cable components that are the interface between the drives and the host controllers. ■ Copper Fibre Channel cables ■ Fibre Channel disk drives and drive blanks. ■ Power and cooling components that include power supplies, cords, and blowers.
Storage System Hardware Components 1 2 3 4 5 6 7 1 2 3 4 5 6 7 EMU I/O module B Blower 1 Power supply 1 Blower 2 Power supply 2 I/O module A CXO7950A Figure 31: Drive enclosure—rear view FC-AL I/O Modules Two I/O modules provide the interface between the drive enclosure elements and the host controllers. See Figure 32 and Figure 33. They route data to and from the drives using Loop A and Loop B, the dual-loop configuration. For redundancy, only dual-controller, dual-loop operation is supported.
Storage System Hardware Components The I/O modules are major components in the Fibre Channel loop. Each module has two ports that can both transmit and receive data for bidirectional operation. Activating a port requires connecting a transceiver to the port via Fibre Channel cables. The port function depends upon the loop. See Figure 34.
Storage System Hardware Components Table 10: Operational I/O Module LED Descriptions and Status Displays Top LED Power LED Bottom LED Off On Off I/O Module is operational On Flashing, then On On Top Port—FC-AL signal detected. Power—Flashes for about 90 seconds. The LED is On constantly; ■ Bottom Port—FC-AL signal detected. This display can occur during the first minute after initial power application. On On On Descriptions ■ ■ Top Port—FC-AL signal detected. Power—Present.
Storage System Hardware Components Table 11: Nonoperational I/O Module LED Descriptions and Status Displays Top LED Power LED Bottom LED On On Off Descriptions Top Port—FC-AL signal detected. Power—Present (After one minute the power LED will be On constantly). ■ Bottom Port—No FC-AL signal detected. Check transceiver and fiber cable connections. ■ ■ Note: This status is also displayed when connected to a FC Loop switch.
Storage System Hardware Components I/O Module Power The I/O module +5 VDC power sensing device protects the modules against overcurrent conditions. If the +5 VDC current exceeds 2.5 A rms (nominal), the sensor opens, removing the +5 VDC input from the I/O module, thereby disabling the module until: ■ The defective I/O module is replaced. ■ The overcurrent condition no longer exists. Note: A disabled I/O module cannot transfer data and disconnects all the drives in the enclosure from the loop.
Storage System Hardware Components Up to 14 disk drives can be installed in a Fibre Channel Drive Enclosure. Figure 36 shows the front view of a Fibre Channel disk drive. CXO6695A Figure 36: Fibre Channel disk drive The HP supplied disk drives conform to the enclosure initiated Enclosure Services Interface (ESI). Caution: Controlling air flow within the enclosure requires installing a drive or a drive blank in each drive bay.
Storage System Hardware Components Status icons CXO7167A Figure 37: Disk drive status icons location The following sections describe the purpose of each of the icons. Table 12 describes each icon. Table 12: Disk Drive Status Icon Descriptions Icon Description Drive Ready This green LED is a “drive ready” indicator and is On when the drive is idle. Drive On-line The green LED for this icon is controlled by the disk drive. The LED may be Off when: ■ There is no controller on the bus. ■ +5.
Storage System Hardware Components Drive Status Displays When displaying status, the LEDs are either On, Off, or Flashing. In some configurations, the host controller can control the status LEDs. The operational drive LED status displays are shown in Table 13. See Table 14 for the nonoperational drive status LED displays. Table 13: Operational Drive Status Displays Drive Ready Drive On-line Drive Failure Description Flashing (medium speed) On Off Initial startup.
Storage System Hardware Components Drive Power The drive voltage backplane sensors (+5.1 VDC and +12.1 VDC) can detect a drive overcurrent condition. When a drive overcurrent condition exists, the sensor disconnects the voltage from the drive to prevent writing data to the drive. The drive is disabled until one of the following conditions occurs: ■ The defective drive is replaced. ■ The overcurrent condition no longer exists.
Storage System Hardware Components Caution: Never remove more than one drive at a time, as this process can cause the enclosure to overheat. To prevent overheating and ensure proper operation, install a drive of equal or greater capacity, or a drive blank, as soon as possible. Power and Cooling Components This section describes the function and general operation of the enclosure power supplies and blowers. Figure 39 identifies the major power supply assembly components.
Storage System Hardware Components The nominal output of each power supply is 499 W, with a peak output of 681 W. A single power supply can support an enclosure with a full complement of disks, blowers, EMU, and I/O module. The power supply circuitry provides protection against: ■ Overloads ■ Short circuits ■ Overheating Power supply status and diagnostic information is reported to the EMU with voltage, current, and temperature signals.
Storage System Hardware Components Should a blower be operating too slowly or stopped (a “blower failure”), internal circuitry automatically causes the remaining operational blower to operate at a higher speed. Simultaneously, the error condition is reported in several ways, including the power supply LED, the audible alarm, the enclosure fault LEDs, and the EMU alphanumeric display. Should both blowers fail, the power supplies automatically shutdown. Note: The failure of a power supply +12.

Storage System Hardware Components Table 19: EMU Display Groups Display Display Group Description En Enclosure Number The enclosure number is the default display and is a decimal number in the range 00 through 14. See “Using the Enclosure Number Feature,” on page 99 for detailed information. Li Bay 1 Loop ID This display group has a single sublevel display that defines the enclosure bay 1 loop ID. Valid loop IDs are in the range 00 through 7F.
Storage System Hardware Components Audible Alarm Operations Whenever an error condition exists, the audible alarm automatically sounds until all errors are corrected. You have the option of either muting or disabling the alarm. These options establish the following conditions: ■ Disabling the audible alarm prevents it from sounding for any error condition. ■ Muting the alarm silences it for the existing condition, but any new condition causes the alarm to sound.
Storage System Hardware Components Using the mute feature ensures that you are aware of more severe errors and provides you with the capability of correcting them promptly. ■ Disable the alarm to prevent any error condition from sounding the alarm. Note: Disabling the alarm does not prevent the EMU alphanumeric display from displaying Er. Nor does it prevent Command View EVA from displaying the error condition report. When the alarm is enabled (on), the bottom pushbutton LED is Off.
Storage System Hardware Components You can mute the audible alarm by completing the following procedure. Note: Er will be displayed in the alphanumeric display when an error condition is present. 1. Press and hold the bottom pushbutton until the LED is On. A muted alarm will remain off until a new error condition occurs. 2. To unmute the alarm, press and hold the bottom pushbutton until the LED is Off. When a new error condition occurs, the alarm will sound.
Storage System Hardware Components Using the Enclosure Number Feature This section provides a general description of the purpose, function, and operation of the EMU enclosure number (En) feature. En Description In a single rack configuration, the En is a decimal number in the range 00 through 14, which is automatically assigned by the enclosure address bus. By default, the two-character alphanumeric display shows this number. Pressing the bottom pushbutton changes the display to En, the En display mode.
Storage System Hardware Components Connecting the enclosures to the cabinet JBs establishes the enclosure address bus. The enclosures are automatically numbered, based on their physical distance from the bottom terminator. The drive enclosure numbers are always assigned by the enclosure address bus. Connecting the EMU CAB ONLY connector to a enclosure address bus JB automatically establishes an En of 01 through 14. Any drive enclosure not connected to the enclosure address bus is assigned an En of 00.

When an error condition is detected, the following action is taken: ■ The EMU alphanumeric display is changed to Er. A condition report has precedence over all other displays.
Storage System Hardware Components Note: An error always generates a condition report. Not all condition reports are generated by errors. The condition types, condition reports, and the interaction between conditions are defined in the following sections. See “EMU Generated Condition Reports” on page 161 for definitions of individual condition reports. Error Condition Types Each error condition is assigned to a category based on its impact on the disk enclosure operation.
Storage System Hardware Components Prompt corrective action should be taken to prevent system degradation. Reporting Characteristics ■ An UNRECOVERABLE condition has precedence over a CRITICAL condition. ■ A CRITICAL condition has precedence over NONCRITICAL and INFORMATION conditions. ■ When a CRITICAL condition is the most severe active condition, the audible alarm sounds three times per alarm cycle, as shown in Table 20 on page 96.
Storage System Hardware Components Reporting Characteristics ■ An INFORMATION condition is the least severe of all the condition reports. ■ When only an INFORMATION condition is active, the audible alarm sounds once per alarm cycle as shown in Table 20 on page 96. Error Queue The EMU maintains an internal error queue for storing error conditions. Each error condition remains in the error queue until the problem is corrected, or for at least 15 seconds after the error is reported.
Storage System Hardware Components Error Condition Report Format Each EMU detected condition generates a condition report containing three pieces of information. ■ Element Type The first two-digit hexadecimal display defines the element type reporting the problem. The format for this display is e.t. with a period after each character. 0.1. through F.F. are valid element types. ■ Element Number The second display is a two-digit decimal number that defines the specific element reporting the problem.

Storage System Hardware Components Reporting Group Feature Another function of the enclosure address bus is to establish reporting groups. Because multiple storage systems can be connected to the same enclosure address bus, reporting groups are used to isolate the communication between storage systems. A component can only communicate with other components within its reporting group. A reporting group (rG) is an HSV100 controller pair and the associated drive enclosures.

HSV Controller Fault Management C This appendix describes how the storage system controller displays events and termination event information. Termination Event information is displayed on the OCP LCD. Command View EVA also detects and displays controller events. This appendix also discusses how to identify and correct problems. Once the initial setup of the storage system is complete, an error condition message has priority over other controller displays.
HSV Controller Fault Management Using Command View EVA Command View EVA provides detailed information about each event affecting system operation in either a Termination Event display or an Event display. These displays are similar, but not identical. GUI Termination Event Display A problem that generates the Termination Event display prevents the system from performing a specific function or process. You can use the information in this display to diagnose and correct the problem.
HSV Controller Fault Management GUI Event Display A problem that generates the Event display reduces the system capabilities. You can use the information in this display to diagnose and correct problems. Note: The major differences between the Event Display and the Termination Event display are: ■ The Event display includes an EIP type field; it does not include a Code Flag field. ■ The Event display includes a Corrective Action Code (CAC) field.
HSV Controller Fault Management Fault Management Displays When you do not have access to Command View EVA, you can display and analyze termination codes (TCs) on the OCP LCD display. You can then use the event text code document, as described in “Interpreting Fault Management Information” on page 193 to determine and implement corrective action. You can also provide this information to the HP authorized service representative should you require additional support.

Customer Replaceable Units D This appendix describes the procedures for replacing Customer Replaceable Units (CRUs).
Customer Replaceable Units ESD Protection When replacing a CRU, you must take precautions to prevent the possibility of electrostatic discharge (ESD) damaging sensitive electronic components. 1. Always transport and store CRUs in a static-free container. 2. Do not remove the CRU from the static-free container until you are ready to install the CRU. 3. Avoid touching the CRU connector pins, leads, or circuitry.
Customer Replaceable Units Common Replacement Procedures The following procedures are common to all CRU replacement procedures. Note: The hotpluggable power supplies, blowers, and drives DO NOT require halting Fibre Channel data transfers. Replacing a pluggable I/O module, transceiver, or a cable always interrupts data transfers on the Fibre Channel loop. Review the controller documentation to determine if replacing an I/O module, transceiver or cable requires removing power. 1.
Customer Replaceable Units Determining CRU Part Numbers All CRUs have an HP 6–3 spare part number on the product label. See Figure 70. This nine-character number appears immediately below the REPLACE WITH HEWLETT-PACKARD SPARE statement. The first six characters (123479) identify the CRU. The last three characters (–002) identify the revision level. The revision level must be the same as, or greater than, the number on the CRU being replaced. The higher the revision level, the later the revision.
Customer Replaceable Units Replacing a Disk Drive Complete the following procedure to replace a disk drive. Caution: Remove only one drive at a time from the enclosure. Removing more than one drive may may cause overheating resulting in data loss. Install a drive of equal or greater capacity or a drive blank before removing another drive. 1. Push in the disk drive Ejector Button, 1 in Figure 71. Pivot the Release Lever 2 to the full, open position. 1 2 CXO6826A Figure 71: Removing a drive 2.
