Background Media Scan And Dynamic Sector Repair Enhance Data Integrity - 3Ware 7000-2 - Escalade RAID Controller User Manual

3ware Escalade ATA RAID Controller User Guide
Staggered Spin Up allows drives to be powered-up into the
Standby power management state to minimize inrush current at
power-up and to allow the controller to sequence the spin-up of
drives. The standby power management state is persistent after
power-down and power-up. This feature is automatically utilized
on drives that support this power management state.
3DM Disk Management Utility runs in the background on the
Escalade ATA RAID Controller's host and allows you to monitor
the controller and maintain the ATA RAID arrays and drives locally
or remotely via a standard web browser. To remotely access 3DM,
you are not required to install any software on your system but you
must have access to the network with the Escalade ATA RAID Con-
troller. 3DM supports hot spare and hot swap for redundant arrays.
Hot swap allows users to replace a failed drive in a redundant array
while the system remains up. Refer to the 3DM Disk Management
Utility chapter for more details and additional features.
To create and delete arrays, you must use the 3ware Disk Array
Configuration Utility. To check array configuration or status, dis-
able write cache, select a hot spare or rebuild a mirrored array, you
can use the 3ware Disk Array Configuration Utility at BIOS time
or 3DM Disk Management Utility in real time. Hot swap is only
available through the 3DM Disk Management Utility.
Background media scan and dynamic sector
repair enhance data integrity
Background Media Scan checks for media errors on any disk drive
connected to the 3ware controller. If the disk drive is part of a
redundant array, error locations that are found and are deemed
repairable are rewritten with the redundant data. This forces the
drive firmware to reallocate the error sectors accordingly. Back-
ground Media Scan is also designed to be minimally intrusive to the
normal controller performance.
