MSA1000 Controller 1 Components The MSA1000 Controller is a drive array controller specifically designed for installation in the MSA1000. The MSA1000 comes equipped with one MSA1000 Controller installed. An additional controller for redundancy can be purchased separately. To ensure uninterrupted service, two copies of the controller firmware are stored in Read Only Memory (ROM) on the controller. See the “Recovery ROM” and “ROM Cloning” sections for more information.
MSA1000 Controller MSA1000 Controller Display Each array controller in an MSA1000 contains an integrated Liquid Crystal Display (LCD). This module is used for displaying informational and error messages, showing the status of the module, and for providing user input when required. Traditional Power-On Self-Test (POST) messages issued by PCI-based array controllers have been combined with runtime event notification messages to create a new set of controller display messages.
MSA1000 Controller Array Accelerator (Battery-backed Cache) The Array Accelerator is a high-performance, upgradeable 256-MB SDRAM DIMM read/write battery-backed cache that can increase performance in database and fault-tolerant configurations. It performs both protected posted-write caching and read-ahead caching, allowing data to be accessed much faster than from disk storage.
MSA1000 Controller Array Accelerator Batteries The Array Accelerator has two rechargeable and replaceable Nickel Metal Hydride (NiMH) battery packs. Under normal operating conditions, these should last for three years before replacement is necessary. They are continuously recharged via a “trickle” charging process whenever the MSA1000 storage system is powered on. The battery packs protect data on the Array Accelerator against equipment failure or power outage for up to four continuous days.
MSA1000 Controller Replacing the MSA1000 Controller Cache Caution: It is important to follow these instructions when replacing components in the MSA1000. If the procedure is done improperly, it is possible to lose data or damage equipment. Refer to Appendix B, “Electrostatic Discharge,” for important information on using the proper procedures. Note: If your system is equipped with a single controller, and you must replace the controller cache, you must power down the system first.
MSA1000 Controller 3. As illustrated in Figure 3, unlatch the controller cover clips 1 on the rear of the controller and then raise the cover 2. Note: The controller in Figure 3 has been rotated so the side and rear of the controller are visible. 4. Simultaneously unlatch the clips that are holding the MSA1000 Controller cache in place 3. 5. Carefully pull the cache away from the controller board 4.
MSA1000 Controller 6. Install the new MSA1000 Controller cache by sliding the new MSA1000 Controller cache into the controller 1. Be sure the side latches are fully engaged 2. See Figure 4. 2 1 Figure 4: Installing the cache module 7. Push the controller in as far as it will go 1; press the latch inward until it is flush against the front panel 2. See Figure 5.
MSA1000 Controller Replacing the Controller Cache Battery Pack WARNING: There is a risk of explosion, fire, or personal injury if the battery pack is replaced incorrectly or mistreated. To reduce the risk: ■ Do not attempt to recharge the battery outside of the controller. ■ Do not expose to water, or to temperatures higher than 60°C. ■ Do not abuse, disassemble, crush, puncture, short external contacts, or dispose of in fire or water. ■ Replace only with the spare designated for this product.

MSA1000 Controller 4. Lift the pack upward to unhook the top of the battery pack. Figure 8: Removing the battery pack Wait about 15 seconds after removing the old battery packs to allow the battery charge monitor to reset. Note: Repeat the replacement procedure for any batteries that were installed at the same time as the batteries that were removed.
MSA1000 Controller 5. Install the new NiMH battery pack by hooking the top of the battery pack to the top of the Array Accelerator with the pack held at a 30-degree angle to the plane of the Array Accelerator board. See Figure 9 for an illustration.
MSA1000 Controller 6. After the pack is hooked in position, swing the pack downward making sure the bottom clip and two pegs line up with the holes in the Array Accelerator. 7. Make sure that the top hook 1 and bottom clip 2 on the battery pack are securely attached to the Array Accelerator. 1 2 Figure 10: Securing the battery pack 8. Installation of the new battery pack is complete. Repeat for the second battery on this battery pack.
MSA1000 Controller Recovery ROM and ROM Cloning Recovery ROM Each MSA1000 Controller contains ROM (Read-Only Memory), which holds the firmware that operates the controller. The Recovery ROM feature stores two complete firmware images in the ROM: one active image and one backup image. When the controller is powering up, it checks both firmware images to ensure they are valid. If either one is not, the valid image will be copied on top of the invalid image to correct it. This is referred to as auto-flashing.
MSA1000 Controller is updated is already operating and processing I/O, then it will not be reset. The MSA1000 will not enter redundant operation and an appropriate message will be shown on the display. After the MSA1000 has been shutdown and powered back on, the controllers will then be able to enter redundant operation. On a subsequent power cycle, both controllers will enter redundant mode.
MSA1000 Controller Table 2: MSA1000 Controller Indicator Descriptions Indicator Function Description 0-2 Busy status These three LEDs are used to progressively represent the processing load on the controller. ON = the controller is idle. OFF = the controller is operating at full capacity. 3-7 Fibre Channel ID Indicates the 5-bit Arbitrated Loop Physical Address (ALPA) assigned to this array controller (not applicable when in fabric mode).
MSA1000 Controller Replacing the MSA1000 Controller If an MSA1000 Controller is failing, informational or error messages will be displayed on the LCD panel of that controller, depending on the condition. The following steps detail how to replace a failed MSA1000 Controller but can also be used to re-seat the controller. Note: Redundancy is supported during a hard drive expansion, migration, or extension process and during regular drive rebuilds.
MSA1000 Controller 3. As illustrated in Figure 13, insert the replacement controller into the chassis 1. 2 1 Figure 13: Installing the replacement controller 4. Push the controller in as far as it will go; press the latch inward until it is flush against the front panel 2.
MSA1000 Controller Updating the Controller Firmware To load the latest version of the firmware for the MSA1000 Controller, go to the HP website at www.hp.com/go/msa1000. From the HP StorageWorks MSA1000 page, select the Software, Firmware & Drivers option. Note: All supported operating systems obtain MSA1000 Controller firmware upgrades from the HP website. Installation instructions are available on the website.
Controller Display Messages 2 Each array controller in an MSA1000 contains an integrated display. This module is used for displaying informational and error messages, showing the current status of the module, and for providing user input when required. Traditional Power-On-Self-Test (POST) messages issued by PCI-based array controllers have been combined with runtime event notification messages to create a new set of controller display messages.
Controller Display Messages About the LCD Messages The display module is capable of holding up to 100 messages. Once this maximum size has been reached, older messages will be removed to make room for newer ones. Messages can be of three types: error, informational, and user input. The display message may specify a box number. The following box numbers are defined. ■ Box 1 is the MSA1000 chassis. ■ Box 2 is the storage enclosure attached to SCSI port A of the MSA1000.
Controller Display Messages These user input messages will only occur during system power on and not during run time. A complete list of possible messages and their meanings is contained in this appendix. The amber indicator to the left of the display text display window will blink on and off when a user input message is currently being viewed and is available for input. If the user has not provided input within the time-out period, the message will remain but the indicator will stop blinking.
Controller Display Messages LCD Message Descriptions The following table contains the defined messages and their components. Table 3: LCD Message Descriptions Message Type Description 00 ARRAY CONTROLLER FIRMWARE VER Informational Displays the current version of the firmware running on the array controller. 01 MSA1000 STARTUP COMPLETE Informational The array controller has completed its power on sequence and is now operational.
