Do not nail or hammer the battery. The battery may be broken or dented and a short circuit may occur inside. As a result, the battery may become overheated, burst or ignite. Do not solder directly to the battery. Page Inspection And Cleaning Precautions 2. Do not work on the unit in a damp or flooded environment. Page Emergency Precautions 2. This will terminate the power supply. If a fire cannot be extinguished when the electric flow has been shut off, use fire- fighting procedures and contact the fire department.
Page Warning Notices 2. Caution statements are indicated by the caution symbol: Table 2. Keep body parts and loose clothing away from the cooling fans. Page Figure 2. Table 2. Page Table 2. Page Service Clearance Requirements The following figure shows the floor area required for installing the equipment.
Install the equipment in a place with the area shown in the figure to avoid problems such as inadequate service clearance or insufficient ventilation. All distances in the following figure are stated in millimeters mm. Page Floor Load Rating 2. The maximum configuration weighs 70 kg.
To ensure adequate load-bearing capacity, plan for the maximum configuration. Page Environmental Specifications And Requirements Close proximity to an apparatus that generates a strong magnetic field Excessive dust Frequent vibrations An inclined floor Note: Do not store or install the equipment in a high temperature environment of 40 degrees centigrade or more - battery life will be shortened.
Chapter 2 Planning for Installation and Operation Page Temperature And Humidity Requirements Note 1: Power current of Nx2 described above is required for operation by a single power supply unit. Note 2: It indicates the current consumption in the usual state. When a power supply failure occurs, the power consumption is provided by the single power supply for the subsystem. Page Vibration And Shock Tolerances 2. The WMS can tolerate vibration and shock within these limits and continue to perform normally.
The user should consider these requirements if installing the WMS near large generators located on the floor above or below the WMS subsystem. Therefore, this value varies on user's system configuration. Page 56 Chapter 2 Planning for Installation and Operation Page Wms Rack-Mount Model 2.
Verify that the AC power unit switch of each power unit is turned off. Verify that the circuit breaker is turned off. Page Subsystem Power Off 2.
Turn off the AC power unit switch of the power unit. Note: The EALM lamp red of the control unit on the rear side of the subsystem may come on between subsystem power-up and entry into the Ready status.
However, it is not a problem if the EALM lamp red goes out until the subsystem enters the Ready status. Page Subsystem Power Off To power off the subsystem: 1. Turn off the main switch. The disk drives can be assigned to data disk s , parity disk s mirror disk s depending on the RAID level. Up to 15 spare disks can be mounted in any location within the configuration.
Page Figure 4. The disk drives can be assigned to data disk s , parity disk s and mirror disk s depending on the RAID level. Page Redundant Power Supplies WMS unit should be connected either to dual power sources or to different power panels, so if there is a power failure on one of the sources, the WMS subsystem can continue full operations using power from the alternate source.
The WMS subsystem supports up to 2 fibre-channel ports. Do not connect anything to host connector 1. Page Table 4. When connecting the WMS directly to the host, the Loop topology is set to the port. Note: Refer to Appendix D Interfaces for the supported conditions of the switch in this subsystem. When FC interface board is added, control unit implements two ports and two host connectors. One port configures FC interface independent of another port, and implements one host connector.
Low-speed blinking Note1 : Indicates that the offline download processing ended. Page Component Locations 4. Page Switch Locations And Functions 4.
Page Connector Locations And Functions 4. Page Led Locations And Functions 4. It is displayed during the maintenance work.
On: It is abnormal. Off: It is operating normally or in a stop state. Chapter 4 Subsystem Architecture and Components Lighting: When on, it indicates that a failure occurs in the controller SENC side , so the controller is inoperable. The following table illustrates the sections that provide the explanation for each model.
According to the customer's model, please read the required section. Fibre Model: Connects disk array subsystem to a host computer with Fibre Channel interface. A maximum of 2 G bytes high capacity cache is supported in the dual configuration. It improves the cache percent hit rate.
The file sharing function supported by connecting to the NAS unit. Page Raid Implementations The stripe consists of two data chunks. RAID5 applies 2 to 15 data disks and has a parity disk which performs the data stripping. RAID 6 applies 2 to 28 data disks, and has two parity disks performing the data stripping. Page Table 5. Table 5. Page Cache Management The data written onto the cache is saved in the event of an electric power failure due to the nonvolatile cache.
The data is assured for 24 hours on the full charge of a standard configuration. Page Figure 5. A maximum of 2, logical units can be set for user LU.
Page Open Systems Features And Functions Middleware is not usually supplied as part of the basic operating system. Chapter 5 Functional and Operational Characteristics The system throughput is improved when this function is applied to an LU that contains data accessed frequently because no latency period is needed to access the disk drive.
Once established, ShadowImage In-System Replication operations continue unattended to provide asynchronous internal data backup. It also acquires utilization rates of resources such as hard disk drives and processors built in the subsystem. This information is displayed with line graphs in the monitor. For each open system, installation is required.
Page Fibre Channel Interface Addressing 6. The WMS can address up to logical unit numbers for one port. The host computer can access the logical unit with the required logical unit number by identifying the port of the disk array subsystem by using the target ID.
Page Figure 6. One Fibre Channel port configures FC interface independent of another Fibre Channel port, and implements one host connector. Host Other Fibre Page Alternate Pathing Alternate Pathing The user should plan for alternate pathing to ensure the highest data availability. The WMS provides up to 2 fibre channel ports or to accommodate alternate pathing for host attachment. The following figure shows a sample of alternate pathing. If the Storage Navigator Modular program is used to configure the IP addresses, also refer to the procedure in section 7.
Note: Set the IP address after the array subsystem becomes ready. Page Configuring The Wms Subsystem 4. Set the system parameters. Restart the subsystem. From the Edit menu, click Add Automatically. Click Start. If there are any special options that need to be set that are specific to the host platform s being used, they will be detailed in the Host Installation Manual for the host platform being used.
To enable Management Mode: 1. System parameters are stored in flash memory. They can be backed up to a disk drive. When the system parameter changes, make a backup copy on the disk drive. Page Storage For Parameters 7. Page Setting Fibre Channel Information 2.
