The auxiliary voltage is used to preserve BBWC data and is available any time that the system power cords are connected to a power supply. 3 Amber Battery Health LED. To interpret the illumination patterns of this LED, see the following table. 4 BBWC Status LED. To interpret the illumination patterns of this LED, see the following table. 26 Appendix A
Smart Array P400 Controller Overview Board Components and Features Table A-6 Interpreting Battery Pack LEDs LED 3 State LED 4 State Interpretation -- One blink every two seconds -- Blink twice, then pause -- One blink per second The system is powered down, and the cache contains data that has not yet been written to the drives. Restore system power as soon as possible to prevent data loss. Data preservation time is extended any time that 3.3 V auxiliary power is available, as indicated by LED 2. In the absence of auxiliary power, battery power alone preserves the data. A fullycharged battery can normally preserve data for at least two days. The battery lifetime also depends on the cache module size. For further information, refer to the controller QuickSpecs on the HP website (http://www.hp.com). The cache microcontroller is waiting for the host controller to communicate. The battery pack is below the minimum charge level and is being charged. Features that require a battery (such as write cache, capacity expansion, stripe size migration, and RAID migration) are temporarily unavailable until charging is complete. The recharge process takes between 15 minutes and two hours, depending on the initial capacity of the battery. -- Steady glow The battery pack is fully charged, and posted write data is stored in the cache. -- Off The battery pack is fully charged, and there is no posted write data in the cache. One blink per second One blink per second An alternating green and amber blink pattern indicates that the cache microcontroller is executing from within its boot loader and receiving new flash code from the host controller. Steady glow -- There is a short circuit across the battery terminals or within the battery pack. BBWC features are disabled until the battery pack is replaced. The life expectancy of a battery pack is typically more than three years. One blink per second -- There is an open circuit across the battery terminals or within the battery pack. BBWC features are disabled until the battery pack is replaced. The life expectancy of a battery pack is typically more than three years. Supported Drive Types You can connect the controller ports to internal SAS backplanes that are connected to SAS drives. Parallel SCSI drives cannot be used with this controller. Appendix A 27

B Fault Management This Appendix provides an overview of the fault management features of the HP Smart Array P400 Controller. This appendix contains the following sections: Fault Management Features on page 30 Fault Management in Supported RAID Configurations on page 31 Appendix B 29
Fault Management Fault Management Features Fault Management Features The Smart Array P400 Controller supports several fault management and data reliability features that minimize the impact of disk drive defects on your systems. Auto-Reliability Monitoring (ARM) A firmware process that operates in the background, scanning physical disks for bad sectors in fault-tolerant logical drives. ARM also verifies the consistency of parity data in logical drives that use RAID 5 or RAID ADG. This process assures that you can recover all data successfully if a disk fails. ARM operates only when you select a fault-tolerant configuration. Dynamic sector repair Automatically remaps any sectors that have media faults detected either during normal operation or by auto reliability monitoring. S.M.A.R.T. An industry-standard diagnostic and failure prediction feature of physical disks, developed by HP in collaboration with the disk drive industry. S.M.A.R.T. monitors several factors that predict imminent physical disk failure due to mechanical causes. These include the condition of the read/write head, the seek error rate, and the spin-up time. When a threshold value is exceeded for one of these factors, the disk sends an alert to the controller that failure is imminent. Thus, you can back up data and replace the disk drive before failure occurs. NOTE An online spare does not become active and start rebuilding when an imminent failure alert is sent, because the degraded disk has not failed yet and is still online. The online spare is activated only after a disk in an array has failed. Drive failure alert features Send an alert message to Event Monitoring Services (EMS) when a physical disk or a logical drive fails. Interim data recovery Occurs if a disk fails in a fault-tolerant configuration. Recovery ROM A redundancy feature that ensures continuous system availability by providing a backup ROM. This feature protects against corruption of a ROM image (for example, by power fluctuation during ROM upgrade). If corruption occurs, the server automatically restarts using the remaining good copy of the ROM image. When you upgrade the ROM, the inactive image (the one not being used by the system) is upgraded. There is not normally any noticeable difference in operation. When you use Recovery ROM for the first time, however, both ROM images are upgraded, causing a boot delay of about 60 seconds. 30 Appendix B
Fault Management Fault Management in Supported RAID Configurations Fault Management in Supported RAID Configurations If a physical disk fails in RAID 1, RAID 1+0, RAID 5, or ADG, the system will still process I/O requests, but at a reduced performance level. Replace the failed physical disk as soon as possible to restore performance and full fault tolerance for the logical drive it belongs to. The risk of continuing operations without replacing a failed physical disk varies depending on the RAID level that has been configured: RAID 1 RAID 1 is configured with a single mirrored pair of disks. If one physical disk fails, the remaining disk in the mirrored pair can still provide all the data. RAID 1+0 A RAID 1+0 configuration has a minimum of four physical disks, and the total number of physical disks is divisible by two to support mirrored pairs. In RAID 1+0, if a physical disk fails, the remaining disk in any mirrored pair still provides all of the data that was on the failed disk. Several physical disks in an array can fail without incurring data loss, as long as no two failed physical disks belong to the same mirrored pair. RAID 5 If a physical disk fails in a RAID 5 configuration, data is recovered using a parity formula and is typically written to an online spare physical disk. If a second physical disk fails before the data from the initial physical disk failure has been rebuilt on the online spare disk, the logical drive fails and data is lost. ADG Similar to RAID 5, ADG relies on a parity scheme to rebuild data if a physical disk fails. However, in an ADG configuration the parity data is duplicated on two different physical disks. As a result, ADG can support the failure of two physical disks without data loss. For a more detailed description of the RAID levels supported by the Smart Array Controllers see the HP Smart Array P400 Support Guide, available at http://www.docs.hp.com in the I/O Cards and Networking section.
