  • Page 13: Product Description

    Product Description General Description Hewlett-Packard’s StorageWorks Disk System 2405 (referred to in this guide as the disk system) is a high-availability Fibre Channel (FC) storage product. Dual optical fiber ports on dual link controllers provide Fibre Channel connections to the host. Fifteen slots accept high-speed, high-capacity FC disks connected to a FC midplane.

  • Page 15: Features

    Status Indicators LEDs on the disk system enable you to detect and replace failed components and thereby prevent or minimize users’ downtime. For additional information about LEDs, see chapter 4, Troubleshooting. On the front of the disk system, a pair of LEDs indicates the status of the disk system, and an LED for each slot shows disk I/O activity: The system power LED (B in Figure 1) indicates that power is on or off.

  • Page 16: Upgradability

    Upgradability You can increase disk system storage capacity by: Replacing disk drives with higher-capacity disk drives Adding disks in unused slots Adding another disk system to a FC loop None of these actions require shutting down the product, but some may require the use of system utilities to manage file systems.

  • Page 17: Components

    Components User-replaceable components enable high availability and easy maintenance. This section describes the following components: Disks and disk fillers LCCs Power supply/fan modules Disks and Disk Fillers Disks, shown in Figure 3, are 3.5-inch Low Profile disks in open metal carriers. Disks are Fibre Channel.

  • Page 20 LCC circuitry provides the following functions: System fault detection Disk address generation Caution If an LCC fails, do not remove it from the disk system until you are ready to replace it with a new one. The failed LCC should remain installed to assure proper cooling for the disk system.

  • Page 21: Power Supply/Fan Module

    Power Supply/Fan Module Redundant, hot-pluggable 340-watt power supplies convert wide-ranging AC voltage from an external main to stable DC output and deliver it to the midplane. Each power supply has an internal fan, an AC receptacle (A in Figure 5), two ejector handles (D) with thumbscrews (C), and 2 LEDs (B).
  • Page 22 Power supplies share the load reciprocally; that is, each supply automatically increases its output to compensate for reduced output from the other, and vice versa. If one power supply fails, the other delivers the entire load. Internal circuitry triggers a fault when the internal fan or other part fails. At the same time, the power fault LED (amber) illuminates, and, if enabled, the hardware event monitor sends an event message.

  • Page 23: Hardware/Software Requirements

    Hardware/Software Requirements The disk system is supported on the following operating systems: HP-UX 11.00 with HWE 0302 or greater HP-UX 11.11 with HWE 0302 or greater For supported servers, see the latest HP 9000 Configuration and Ordering Guide.

  • Page 24: Single Host Basic Configuration

    Single Host Basic Configuration The maximum number of disk systems supported on a Fibre Channel Arbitrated Loop (FC-AL) is seven. The maximum storage capacity with this configuration is approximately 7.5 Terabytes (105 disk modules at the 73 Gbyte capacity point). This configuration does not provide any redundancy to the data path, however there is some hardware redundancy provided by the enclosures themselves (power supplies).

  • Page 25: Single Host Pv Links Configuration

    Single Host PV Links Configuration Data path redundancy can be achieved with the configuration shown in Figure . Using an additional host bus adapter and the LVM software, pvlinks can be created to provide a redundant path to data. A separate mirror path can be created for data protection, also.

  • Page 26: Two Host High Availability Configuration

    Two Host High Availability Configuration Figure 8 shows a basic high availability configuration. Each disk system can still be configured using pvlinks and mirroring. High availability software protects against a disk system failure. A failure in a cable or LCC will result in a loop failure.

  • Page 27: Four Host Hub Configuration

    Four Host Hub Configuration The disk system can run at 2 Gb/s speed. For legacy systems a four host configuration could be used for an advanced high availability environment at 1 Gb/s speed. See Figure 9, below. The performance of this configuration is limited to a maximum of 200MB/s (100 MB/s per loop).

  • Page 72: Step 6: Connect Fc And Power Cables

    Step 6: Connect FC and Power Cables Connect the front-end fiber-optic cables. Front-end fiber-optic cable connections depend on the type of connectors used by the controller and the type of HBA to which the controller is connected. The Virtual Array Products use integrated LC (small form factor) connectors.

  • Page 75: Step 7: Install Disk Modules

    Step 7: Install Disk Modules Caution Touching exposed areas on the disk can cause electrical discharge and disable the disk. Be sure you are grounded and be careful not to touch exposed circuits. Disk modules are fragile and ESD sensitive. Dropping one end of the disk just two inches is enough to cause permanent damage.

  • Page 76: Step 8: Turn On The Disk System

    Determine which slots, 1 through 15, will contain disk modules and which will contain fillers. At least two slots must contain disk modules. Put on the ESD strap and attach the other end of the strap appropriately. Caution Disk modules are fragile. Handle carefully. Be careful to grasp the disk module by its handle and avoid touching exposed circuitry.

  • Page 111: Disk Module

    Disk Module Add or replace disks to increase storage capacity or eliminate faults. (See chapter 4 for troubleshooting procedures.) Disks must be Fibre Channel (FC) and 3.5 inches wide but can vary in capacity. For current information about supported disks, consult an HP sales representative. You do not need to turn off the disk system to replace a disk or filler.

  • Page 112: To Determine If The Physical Volume Is Attached

    The following messages will appear if the disk is defective: VGDISPLAY: WARNING: COULDN’T QUERY PHYSICAL VOLUME “/dev/dsk/c2t4d0” THE SPECIFIED PATH DOES NOT CORRESPOND TO PHYSICAL VOLUME ATTACHED TO THE VOLUME GROUP VGDISPLAY: WARNING: COULDN’T QUERY ALL OF THE PHYSICAL VOLUMES If either of the above messages appears, follow the replacement instructions for unattached physical volumes (page 114).

Run IOSCAN on the host and verify that the replacement disk module is “claimed.” Restore file systems and data as needed (see Preparation on page 111). Replace an LCC when troubleshooting shows that the card is faulty (see “Isolating Causes”...

  • Page 118: Figure 58 Lcc Removal And Replacement

    Open the cam levers (B) by pulling them away from the center of the card. This disconnects the LCC pins from the midplane. Pull the LCC out of the slot (C). Replace the LCC immediately if the product is in use (see next step). Attach the clip end of your ESD wrist strap to the ground stud at the top of the rack.

  • Page 119: Figure 59 Lcc Address Switches And Leds

    Set address switches on the new LCC to match settings on the peer LCC. Caution The address switches must have the same settings on both LCCs. Open the cam levers (see Figure 58) by pulling them away from the center of the card.

  • Page 120: Power Supply

    Power Supply Replace a power supply as soon as possible when troubleshooting indicates a power supply failure (see “Isolating Causes” in Chapter 4). If a power supply fails, the remaining power supply provides proper voltage to the disk system. However, if the remaining power supply fails before the first power supply is replaced, the disk system will turn off.

  • Page 121: Figure 60 Power Supply Removal And Replacement

    Slide the replacement power supply into the empty slot (D in Figure 60). The power supply begins to engage the midplane with 3/8 inch (8mm) still exposed. Rotate the handles back toward the center of the power supply module to draw the power supply the last 3/8 inch into the chassis and firmly seat the power supply on the midplane.

  • Page 122: Disk System

    Disk System Use this procedure if you need to move or remove and replace the disk system in the rack. For example, you must remove the disk system from the rack in order to replace the midplane or power switch assembly. Twenty four inches of vertical space is required in the rack if the midplane or power switch assembly are to be replaced without removing the disk system from the rack.

  • Page 123: Figure 61 Disk System Removal And Replacement

    Push the disconnected disk system forward or lift it completely out of the rack, as needed. When you are ready to replace the disk system, push the chassis back into the rack. Insert and tighten the front mounting screws. Reinstall the power supply/fan module(s). Reinstall the disk modules in the slots from which they were removed.

  • Page 124: Top Cover (Hp-Qualified Only)

    Top Cover (HP-Qualified Only) The following procedure is for HP-qualified personnel only. The top cover, which is not an orderable part, will need to be removed and replaced to service the light pipes, the power switch extension arm, or the midplane.

  • Page 125: Figure 62 Top Cover Assembly

    Slide the cover toward the middle of the chassis. Insert the three flathead screws through the holes as shown in Figure 62 and tighten. Reconnect the disk system. See page 120. Reinstall disks. See page 111. Removal and Replacement 125...

  • Page 126: Midplane (Hp-Qualified Only)

    Midplane (HP-Qualified Only) The midplane board is replaceable by HP-qualified personnel only. Replace the midplane based on troubleshooting results (see “Isolating Causes” in chapter 4). Disks, LCCs, and power supply/fan modules connect to the midplane. The power must be OFF and the top cover removed in order to remove and replace the midplane board.
  • Page 127 Remove the eight Torx T15 screws along the top and bottom edges of the midplane (see Figure 63). Pull the midplane forward to clear alignment pins and lift it up and out of the disk system. To replace the midplane: Stand the new midplane inside the chassis and push it over the alignment pins.
