    Hardware features During POST, each component controller loads its own instance of the required driver and sets its own configuration using ORCA. The dual controller is displayed in both Systems Insight Manager and ACU as two separate entities in one slot. In these utilities, the slot number label for the expansion module has a lowercase b suffix, while the slot number label for the main controller has no suffix.

    HP Smart Array 6400 Series Controllers User Guide 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 3.

  • Page 17: Connecting Storage Devices

    Installing the controller hardware 7. Replace the access panel, and secure it with screws if any are present. CAUTION: Do not operate the server for long periods without the access panel. Operating the server without the access panel results in improper airflow and improper cooling that can lead to thermal damage.

  • Page 27: Using Orca

    Configuring an array Using ORCA 1. Power up the server. POST runs, and any array controllers that are in the server are initialized one at a time. During each controller initialization process, POST halts for several seconds while an ORCA prompt message appears.

  • Page 30: Expanding An Array

    HP Smart Array 6400 Series Controllers User Guide Accelerator ratio The controller has an onboard cache called an Array Accelerator, which performs both write-posting and read-ahead caching. The setting in CPQONLIN determines the amount of memory allocated to the read and write caches. For example, if the accelerator ratio is set to Read 75%:Write 25%, 75% of Array Accelerator cache is dedicated to read-ahead cache and 25% is dedicated to the write-posting cache.

  • Page 42: Compromised Fault Tolerance

    HP Smart Array 6400 Series Controllers User Guide RAID 1+0 configurations can tolerate multiple drive failures as long as no failed drives are mirrored to one another. RAID 5 configurations can tolerate one drive failure. RAID ADG configurations can tolerate simultaneous failure of two drives. Compromised fault tolerance If more hard drives fail than the fault-tolerance method allows, fault tolerance is compromised, and the logical drive fails.

  • Page 43: Replacing Hard Drives

    Replacing, moving, or adding hard drives 3. Replace any failed drives. 4. After you have replaced the failed drives, fault tolerance may again be compromised. If so, cycle the power again. If the 1779 POST message is displayed: a. Press the F2 key to re-enable the logical drives. b.
  • Page 44 HP Smart Array 6400 Series Controllers User Guide If you set the SCSI ID jumpers manually: Check the ID value of the removed drive to be sure that it corresponds to the ID of the drive marked as failed. Set the same ID value on the replacement drive to prevent SCSI ID conflicts.

  • Page 45: Automatic Data Recovery (Rebuild)

    Replacing, moving, or adding hard drives In RAID ADG configurations, any two drives in the array can be replaced simultaneously. In RAID 1+0 configurations, any drives that are not mirrored to other removed or failed drives can be simultaneously replaced offline without data loss.

  • Page 46: Upgrading Hard Drive Capacity

    HP Smart Array 6400 Series Controllers User Guide The number of drives in the array (for RAID 5 and RAID ADG) Allow approximately 15 minutes per gigabyte for the rebuild process to be completed. This figure is conservative, and newer drive models usually require less time to rebuild.

  • Page 47: Moving Drives And Arrays

    Replacing, moving, or adding hard drives CAUTION: Because it can take up to 15 minutes per gigabyte to rebuild the data in the new configuration, the system is unprotected against drive failure for many hours while a given drive is upgraded. Perform drive capacity upgrades only during periods of minimal system activity.
