    1 Getting startedFirst, decide what type of expansion you will perform; this will determine which hardwarecomponents are needed.

    •   EVA4400 components—The EVA4400 can support a maximum of 8 disk enclosures (mainand expansion racks combined). If the main rack containing the EVA4400 includes non-EVAcomponents (such as servers or switches) is full, you can add an expansion rack.

    •   EVA4400 2C8D main rack—The main rack is full with 2 controllers and 8 disk enclosures. Ifthere is insufficient space to put all 8 disk enclosures in the main rack, disk enclosures can beadded in an expansion rack.

    •   EVA4400 0C7D expansion rack

    The expansion rack can contain up to 7 disk enclosures. To add disk enclosures to the mainrack of an EVA4400, see the  HP 4400 Enterprise Virtual Array Installation Guide . Theinstallation guide contains cabling diagrams for various configurations. This document showshow to add disk enclosures in an expansion rack to an existing configuration.

    2 Installing disk enclosures in the expansion rack

    Before you beginRead the following warnings and cautions before installing the disk enclosure.

    CAUTION:

    1.   Make sure that the cabinet and all equipment mounted in the cabinet have a reliable groundconnection. Verify that the total current of the cabinet components does not exceed the currentrating of the power distribution unit or the power distribution modules.

    2.   Parts can be damaged by electrostatic discharge. User proper anti-static protection. Foradditional information, see the documentation that shipped with your system.

    Rack stabilityRack stability protects personnel and equipment.

     WARNING!   To reduce the risk of personal injury or damage to equipment:

    •   Extend leveling jacks to the floor.

    •   Ensure that the full weight of the rack rests on the leveling jacks.

    •   Install stabilizing feet on the rack.

    •   In multiple-rack installations, fasten racks together securely.

    •   Extend only one rack component at a time. Racks can become unstable if more than onecomponent is extended.

    Make sure that the rack is sufficiently stable. If provided, lower the rack leveler feet and makesure any stabilizers are installed. If provided, extend the rack anti-tip device. Failure to extendthe anti-tip device could result in personal injury or damage if the rack tips over.

    3. Repeat Step 1 and Step 2 for the remaining rail.

    Convert the railsThe rail kit supplied with the disk enclosure comes configured for square-hole racks.

    IMPORTANT:   Do not remove the pins from the ends of the rails unless you are converting therails for use in round-hole racks. These load-bearing pins are designed to fit through the holeswithout being removed.

    To convert the rails for a round-hole rack:1. Locate the bag of eight round-hole pins included in the rail kit.2. Use a No. 2 Phillips screwdriver to remove the standard pins from the front and back of the

    left and right rails (four pins on each rail).

    Figure 6 Square-hole to round-hole rack conversion

    3. Insert the round-hole pins into the eight holes on the rails where the standard pins wereremoved.

     Attach the rails

    NOTE:   The left and right rails are designated by the letters R (right) and L (left) stamped into themetal on the front of the rack.

    8 Installing disk enclosures in the expansion rack

    9/21

    Consider the following when installing the rail assembly:

    •   Installing the rails does not require any tools for assembly.

    •   HP recommends you install all the rail kits before installing any other components.

    •   Ensure that the rails are level, particularly front to rear in their corresponding front and rearrail hole (U) locations, before installing any other components.

     WARNING!   Before you begin, ensure that the rack is sufficiently stable. If provided, lower the

    rack leveler feet and make sure any required stabilizers are installed. If provided, extend the anti-tipdevice. Failure to extend the anti-tip device could cause personal injury or damage if the rack tipsover.

    1. On the rear of the rail, squeeze the scissors latch (1, Figure 7 (page 9)) together to insertthe rail and pins through the rack holes (2) until the latch engages.

    Figure 7 Attaching the rear rail

    2. On the front of the rail, pull and rotate the locking latch to release the scissors latch (1,Figure 8 (page 10)) and then squeeze the scissors latch together to insert the rail and pinsthrough the rack upright holes until the latch engages (3).

    CAUTION:   Ensure that the locking latch lever between the scissors lock arms is engaged.

     Attach the rails 9

    Figure 8 Attaching the front rail

    3. Loosen the locking nut (1, Figure 9 (page 10)) on the shipping retaining bracket (2) and slidethe bracket to the farthest position on the rear of the rail. This moves the bracket out of the

    way to let you install the chassis in the rails.Figure 9 Locking nut and retaining bracket

    4. After attaching the rail, grab and move the rail gently to be sure it is firmly engaged in therack and that all latches are engaged in the rack holes.

    5. Repeat Step 1 through Step 4 for the other rail.

    Install the enclosures

     WARNING!   Install hard drives in the enclosures only after securing the enclosures in the rack:

    •   An enclosure populated with hard drives is too heavy to lift safely.

    •   Movement of an enclosure during installation might damage the internal storage media ofinstalled hard drives.

    10 Installing disk enclosures in the expansion rack

  • 8/16/2019 HP 4400 Enterprise Virtual Array Expansion Rack Reference Guide.pdf

    11/21

    CAUTION:   Follow industry-standard practices when handling hard drives. Internal storage mediacan be damaged when drives are shaken, dropped, or roughly placed on a work surface. Wheninstalling a hard drive, make sure it is fully seated in the drive bay. To remove a hard drive, pressthe release button and pull the drive only slightly out of the enclosure. Then, to allow time for theinternal disk to stop rotating, wait approximately 10 seconds before completely removing the drivefrom the enclosure.

    1. Pull the bezel covers that are installed over the thumbscrews on the front of the enclosurestraight out (see Figure 10 (page 11)).

    CAUTION:   Do not disengage the top and rotate the bezel covers downward — this canbreak the locking tabs that secure the covers to the enclosure.

    Figure 10 Removing bezels from enclosure

    2. Align the enclosure with the rails and slide it into the rack Figure 11 (page 11).

    CAUTION:   The chassis is back-heavy. Pick it up carefully to maintain your balance.

    12/21

    3. Continue sliding the enclosure into the rack until the front edge is flush with the front of therack (1, Figure 12 (page 12)). Tighten the enclosure thumbscrews into the rack (2), takingcare to not strip the Phillips-head thumbscrews.

    Figure 12 Tighten disk enclosure thumbscrews

    4. Reattach the front bezel covers.5. At the rear of the rack, loosen the thumbscrew on the shipping retaining bracket (1,

    Figure 14 (page 13)) and slide the bracket forward (2,  Figure 14 (page 13)) until the tabengages the slot in the chassis. Tighten the thumbscrew on the bracket.

    Figure 13 Secure rear of enclosure

    Install the hard drives in the enclosure drive bays After securing the disk enclosures in the rack, install the hard drives into the drive bays. Drivesmust be installed in the proper bay sequence (see Figure 14 (page 13)) in the enclosures foroptimum HP P6000 Command View performance and data integrity.

    12 Installing disk enclosures in the expansion rack

  • 8/16/2019 HP 4400 Enterprise Virtual Array Expansion Rack Reference Guide.pdf

    13/21

    For example, if you have four enclosures and eight drives, you could install four drives in bay 1of each enclosure and four drives in bay 2 of each enclosure. Do not install all the drives in enclosure1 and leave the other enclosures empty.

    Figure 14 Disk drive bay numbering

    Follow these guidelines:1.   Install the largest disk drives first, continuing with sizes in descending order (for example,

    1000 GB first, then 450 GB, down to 146 GB drives) balancing drives across the enclosures.2.   Install drives starting from the bottom (slot 1 on the enclosure shelf, the highest –LH slot), then

    install upward until you have installed the largest drive quantity in slot 1 of each shelf.3.   Proceed to slot 2 of each shelf, and so on.4.   Install the next largest drive size until all of that size have been installed.5.   Repeat the process for each drive size until all drives have been installed.

    1. To install disk drives:a. Insert the disk drive into the drive bay (1, Figure 15 (page 13)) until it clicks, locking the

    drive.b. Rotate the drive lever to the right (2, Figure 15 (page 13)) until it locks.c. Ensure the drives are installed in the proper sequence, following the numbering scheme

    in Figure 14 (page 13).

    Prepare the expansion rack for connection to the main rack

    For EVA4400 cabling, see the HP 4400 Enterprise Virtual Array Installation Guide , Appendix A.To prepare to connect the expansion rack to the main rack, follow these steps.

    Physically inspect the expansion rackPhysically inspect the expansion rack to verify that the following conditions are met:

    •   All enclosures and enclosure modules are properly installed and seated.

    •   Each power supply is connected to an electrical outlet in the rack.

    •   The end connector of each cable is plugged into a disk enclosure I/O module.

    •   The primary cable (on the right side) is black and the secondary cable (on the left side) is

    gray.

    3 Connecting the main rack to the expansion rackYou can complete the connection between the main and expansion racks while the controllers arepowered on (online) or off (offline). The offline method is preferred if downtime is available.

    Routing cables in the expansion rack

    NOTE:   The cables used are Optical fiber channel cables supplied in the HP P6000 EVA 5mExpansion Cable Kit AP712A kit (four in the kit).

    •   Route the cables along the side of each rack so they can be secured and kept out of the way.

    •   Route all the expansion cables as a single bundle out of the bottom of the expansion rack, orout of the top access in the host rack, to the top access in the expansion rack.

    •   Route the cables underneath the suspended flooring, if present.

    •   Bring the cables into the top or bottom of the main rack and separate them into two bundles.

    •   Wrap the excess cables around the spools that are provided in the expansion accessory kit.

    CAUTION:   Do not allow fiber cables to bend with a radius smaller than 30 mm (1.2 in).Overbending compromises the integrity of the glass fiber transmission. To avoid deformingor possibly breaking copper cables, do not allow them to bend with a radius smaller than 60mm (2.4 in).

    1. Verify that each fabric Fibre Channel switch to which the HSV controllers are connected ispowered up and fully booted. The power indicator on each switch should be on.

    If you must power up the SAN switches, wait for them to complete their power-on boot processbefore proceeding. This may take several minutes.

    NOTE:   Before applying power to the rack, ensure that the power switch on each HSVcontroller is off.

    2. Power on the circuit breakers on both EVA rack PDUs. Verify that all drive enclosures areoperating properly. The status indicator and the power indicator should be on (green).3. 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).4. Power on the upper controller (Controller A). It takes the role of master controller.5. Wait 10 seconds and then power on the lower controller (Controller B). It takes the role of

    slave controller.6. Verify that the Operator Control Panel (OCP) display on each controller displays the storage

    system name and the EVA WWN.7. Start HP Command View EVA and verify connection to the storage system. If the storage system

    is not visible, click  HSV Storage Network in the Navigation pane, and then click  Discover  in

    the Content pane to discover the array.

    NOTE:   If the storage system is still not visible, reboot the management server to re-establishthe communication link.

    8. Check the storage system status using HP Command View EVA to ensure everything is operatingproperly. If any status indicator is not normal, check the log files or contact your HP-authorizedservice provider for assistance.
