    Installing the controller hardware Preparing the server Back up all data. Close all applications. Power down the server. CAUTION: In systems that use external data storage, be sure that the server is the first unit to be powered down and the last to be powered back up. Taking this precaution ensures that the system does not erroneously mark the drives as failed when the server is powered up.

  • Page 13: Connecting Storage Devices

    Close or replace the access panel, and then secure it with thumbscrews, if any are present. CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating the server in this manner results in improper airflow and improper cooling that can lead to thermal damage.

    Pull the right hand portion of the battery case away from the battery, and simultaneously rotate the battery pack into the opening. Connect the battery cable to the battery and the cache. Route the battery cable so that the cache and battery can be removed together.
  • Page 25 Remove the controller from the server. Pull the flanges on the battery clip outward (1), and then swivel the clip 180 degrees so that it rests on the batteries (2). Slide the batteries toward the right edge of the controller, away from the bracket. While holding the battery assembly, tilt the clip until it is at about 30 degrees to the batteries, and then push the clip in line with the clip hinges until the clip detaches from the batteries.
  • Page 26 Slide the batteries apart (2). Dispose of the exhausted or faulty battery using environmentally approved procedures ("Battery replacement notice" on page 51). Position the new battery and the remaining good battery as indicated, push them together, and then slide them until they are aligned. The batteries combine into one unit. Install the battery clip.
  • Page 27 Push the clip at the hinges until the clip clicks into place. Reinstall the batteries. Hold the controller board near the DIMM socket and at the top and right edges to minimize bending of the board. Position the batteries so that the pegs A on the underside of each battery are in the appropriate holes B on the controller board and pegs C are in slots D.
  • Page 28 Slide the batteries toward the board bracket until they are firmly seated against the connectors on the cache module. Secure the battery clip to the controller board: Swivel the clip over the cache module (1). Push the clip firmly at both ends (2) until it clicks into place under the controller board. Reinstall the controller in the server.

  • Page 29: Replacing The P800 Cache Module Or Controller

    Replacing the P800 cache module or controller CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly grounded before beginning this procedure. Close all applications, and then power down the server. This procedure flushes all data from the cache.
  • Page 30 Slide the battery assembly and the cache module off the controller board (2). The procedure at this point depends on whether you are replacing the controller or the cache module. If you are replacing the controller, go directly to the next step. If you are replacing the cache module, pull it out of the battery assembly, install the new cache module in its place, and then go to the next step.
  • Page 31 Slide the batteries toward the board bracket until the connectors on the cache module are firmly seated in the DIMM connector. (When the cache module is correctly seated, the gold contacts on the cache module are completely hidden within the DIMM connector.) Secure the battery clip to the controller board.

  • Page 32: Replacing, Moving, Or Adding Hard Drives

    Replacing, moving, or adding hard drives Identifying the status of a hard drive When a drive is configured as a part of an array and connected to a powered-up controller, the condition of the drive can be determined from the illumination pattern of the hard drive status lights (LEDs). Item Description Fault/UID LED (amber/blue)

  • Page 33: Recognizing Hard Drive Failure

    Online/activity Fault/UID LED Interpretation LED (green) (amber/blue) Flashing regularly Amber, flashing Do not remove the drive. Removing a drive may terminate the (1 Hz) regularly (1 Hz) current operation and cause data loss. The drive is part of an array that is undergoing capacity expansion or stripe migration, but a predictive failure alert has been received for this drive.

  • Page 34: Effects Of A Hard Drive Failure

    CAUTION: Sometimes, a drive that has previously been failed by the controller may seem to be operational after the system is power-cycled or (for a hot-pluggable drive) after the drive has been removed and reinserted. However, continued use of such marginal drives may eventually result in data loss.

  • Page 35: Replacing Hard Drives

    Recreate the partitions. Restore all data from backup. To minimize the risk of data loss that is caused by compromised fault tolerance, make frequent backups of all logical volumes. Replacing hard drives The most common reason for replacing a hard drive is that it has failed. However, another reason is to gradually increase the storage capacity of the entire system.

  • Page 36: Automatic Data Recovery (Rebuild)

    • Do not remove a second drive from an array until the first failed or missing drive has been replaced and the rebuild process is complete. (The rebuild is complete when the Online/Activity LED on the front of the drive stops blinking.) The following cases are exceptions: In RAID 6 (ADG) configurations, any two drives in the array can be replaced simultaneously.
  • Page 37 CAUTION: If the Online/Activity LED on the replacement drive does not light up while the corresponding LEDs on other drives in the array are active, the rebuild process has abnormally terminated. The amber Fault LED of one or more drives might also be illuminated. Refer to "Abnormal termination of a rebuild (on page 37)"...

  • Page 38: Upgrading Hard Drive Capacity

    Remove the drive that was originally to be replaced, and reinsert the replacement physical drive. The rebuild process automatically restarts. When the rebuild process has finished, replace the newly failed drive. However, if the newly failed drive has not recovered: Remove the drive that was originally to be replaced, and reinsert the replacement physical drive.

  • Page 39: Adding Drives

    • The controller is not running capacity expansion, capacity extension, or RAID or stripe size migration. • The controller is using the latest firmware version (recommended). Before you move an array to another controller: • If the other controller is already connected to one or more arrays of configured logical drives, the total number of logical drives on the controller after the drives have been moved must not exceed the number of logical drives that the controller supports.
  • Page 40 drive in the array. Each logical drive keeps the same fault-tolerance method in the enlarged array that it had in the smaller array. When the expansion process has finished, you can use the liberated storage capacity on the enlarged array to create new logical drives. Alternatively, you can use ACU to enlarge (extend) one of the original logical drives.

  • Page 41: Diagnosing Array Problems

    Diagnosing array problems Controller board runtime LEDs Immediately after you power up the server, the controller runtime LEDs illuminate briefly in a predetermined pattern as part of the POST sequence. At all other times during server operation, the illumination pattern of the runtime LEDs indicates the status of the controller. To determine the controller status, see the appropriate controller-specific section.
