Module A can only be installed at the right end of the enclosure, and module B can only be installed at the left end of the enclosure. See Figure 11. Each I/O module has two ports that can both transmit and receive data for bidirectional operation. Activating a port requires connecting a FC cable to the port.
Table 6 Operational I/O module status indicators Upper Power Lower Off On Off • I/O Module is operational On Flashing, then On On • Top port—Fibre Channel drive enclosure signal detected. • Power—Flashes for about 90 seconds after initial power application, then remains constant. • Bottom port—Fibre Channel drive enclosure signal detected. 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 14. 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.
Disk drive status indicators Three status indicators display the drive operational status. Figure 16 shows the disk drive status indicators. Table 8 provides a description of each status indicator. Figure 16 Disk drive status indicators 1. Activity 2. Online 3. Fault Table 8 Disk drive status indicator descriptions Description Status indicator Activity Online Fault This green status indicator flashes when the disk drive is being accessed.

Blower tabs (wine-colored) 6. Blower Power supplies The two power supplies mount in the rear of the enclosure (see Figure 27). The supplies are autoranging and operate on a country-specific AC input voltage of 202 to 240 VAC ±10%, 50 to 60 Hz, ±5%, (188 to 264 VAC, 47 to 63 Hz).
Blowers The power supply–mounted blowers cool the enclosure by circulating air through the enclosure. The blowers, under the control of the EMU or the associated power supply, can operate at multiple speeds. This ensures that when the enclosure temperature changes the blowers can automatically adjust the air flow. If a blower is operating too slowly or has stopped (a “blower failure”), internal circuitry automatically operates the remaining blower at a higher speed.

Enclosure power—When both the +5 VDC and +12 VDC are correct, this green LED is on. Enclosure fault—This amber LED is normally off. The LED is lit when an enclosure error condition exists. 2. Alphanumeric display—A two-character, seven–segment alphanumeric display of the enclosure functions and status. 3.
NOTE: Although the EMU can determine the logical address of a drive, the EMU can neither display nor change this information. HP Command View EVA can display the addresses from the EMU-supplied status information. EMU monitoring functions The internal EMU circuitry monitors the enclosure and component functions listed in Table 12.
EMU indicator displays The EMU status indicators are located above the alphanumeric display. See Figure 19. These indicators present the same information as those on the front, lower right corner of the enclosure. You can determine the EMU and enclosure status using the information in EMU LED displays table. Table 14 EMU status indications EMU indicator (green) Power indicator (green) Fault indicator (amber) Status and recommended actions Flashing Flashing Flashing The EMU Locate function is active.
Table 15 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 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.
Table 16 Audible alarm sound patterns Condition type Cycle 1 Cycle 2 UNRECOVERABLE CRITICAL NONCRITICAL INFORMATION Legend Alarm On Alarm Off Controlling the audible alarm You can control the alarm with the push buttons. This process includes muting, enabling, and disabling. When an error condition exists, the alphanumeric display reads Er, the alarm sounds, and you can: • Correct all errors, thereby silencing the alarm until a new error occurs.
3. Press and release the top push button to change the display to a flashing On (Audible Alarm On). 4. Press and release the bottom push button to accept the change and to display Au. The bottom push button indicator is now off. Muting or unmuting the audible alarm You may want to mute the alarm in the following situations: • The error does not require immediate corrective action. • You cannot correct the error at this time. For example, the error may require a replacement part.
Enclosure number feature This section provides a 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. NOTE: Your storage system may use an enclosure address bus higher than 14 if your configuration includes an optional expansion cabinet. The enclosure address bus connection determines the En.

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.
Analyzing condition reports Analyzing each error condition report involves three steps: 1. Identifying the element. 2. Determining the major problem. 3. Defining additional problem information. Reporting group feature Another function of the enclosure address bus is to provide communications within a reporting group. A Reporting Group (rG) is an HSV210 controller pair and the associated drive enclosures.
Fibre Channel loop switches The EVA8000 uses four FC loop switches (Figure 22) to connect all of the drive enclosures to the controller pair using FC cables. Each switch acts as a central point of interconnection and establishes a fault-tolerant physical loop topology. 42 1 3 5 42 3 4 6 7 8 9 10 Figure 22 FC loop switch 1. Handle 2. Bezel snaps 3.

Table 18 Fibre Channel switch system indicators Description System indicator Power A green indicator. When lit, this indicates that the switch is plugged in and the internal power is functional. Loop operational A green indicator. When lit, this indicates that the Fibre Channel loop has completed initialization and is now operational. POST fault An amber indicator. When lit, this indicates that the internal hardware self-test failed and the switch will not function. OvertTemp An amber indicator.
Table 20 Fibre Channel switch basic troubleshooting Problem Recommended action SFPs are installed in ports but no indicators are lit. 1. Verify that the power cord is firmly seated in the switch and is connected to the power outlet.2. Check the power indicator to verify that the switch is on. SFP is installed, but the Port Bypassed indicator is lit. Re-seat the SFP. If the same condition occurs, the SFP is probably faulty and should be replaced.

Power distribution AC power is distributed to the rack through a dual Power Distribution Unit (PDU) assembly mounted at the bottom rear of the rack. The characteristics of the fully-redundant rack power configuration are as follows: • Each PDU is connected to a separate circuit breaker-protected, 30–A AC site power source (220–240 VAC ±10%, 50 or 60–Hz, ±5%). Figure 30 illustrates the compatible 60–Hz and 50–Hz wall receptacles.
Each of the two PDU power cables has an AC power source specific connector. The circuit breaker-controlled PDU outputs are routed to a group of four AC receptacles (see Figure 31). The voltages are then routed to PDMs, sometimes referred to as AC power strips, mounted on the two vertical rails in the rear of the rack. 1 2 3 5 4 5 0130a Figure 31 Dual PDU assembly 1. PDU 1 2. PDU 2 3. Circuit breakers 4. AC receptacles 5. Mounting hardware PDU 1 PDU 1 connects to AC power distribution source 1.
CAUTION: The AC power distribution within a rack ensures a balanced load to each PDU and reduces the possibility of an overload condition. Changing the cabling to or from a PDM could cause an overload condition. HP supports only the AC power distributions defined in this user guide. 1 2 3 0131a Figure 32 Rack PDM 1. Power receptacles 2.

PDU 2 Rack System/E power distribution components AC power is distributed to the Rack System/E rack through Power Distribution Units (PDU) mounted on the two vertical rails in the rear of the rack. Up to four PDUs can be mounted in the rack—two mounted on the right side of the cabinet and two mounted on the left side. Each of the PDU power cables has an AC power source specific connector.
Moving and stabilizing a rack WARNING! The physical size and weight of the rack requires a minimum of two people to move. If one person tries to move the rack, injury may occur. To ensure stability of the rack, always push on the lower half of the rack. Be especially careful when moving the rack over any bump (e.g., door sills, ramp edges, carpet edges, or elevator openings). When the rack is moved over a bump, there is a potential for it to tip over.

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.
