seconds
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 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.

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
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.

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.
