Create a Hot Spare Drive for Mirrored Arrays
For automatic rebuilds of a mirrored array, attach a spare drive to the
PDC20319 SATA RAID Controller. Drives that are not assigned to an array and
are the same size or larger than the original will be used for the automatic
rebuild. This is performed in the background under all supported operating
systems, except DOS. At a later time, the system can be turned off and the
failed drive can be physically removed.
How the PDC20319 SATA RAID Controller Orders Arrays
During startup, the disk arrays on the PDC20319 are recognized in this order:
1. The array set to bootable in the FastBuild Setup.
2. The Array number (i.e. Array 0, Array 1…). This would be involved in
determining which drive letters will be assigned to each disk array.
How the PDC20319 SATA RAID Controller Saves Array
Information
All disk array data is saved into the reserved sector on each array member.
Promise suggests that users record their disk array information for future
reference.
Another feature of the PDC20319 SATA RAID Controller disk array system is to
recognize drive members even if drives are moved between different
PDC20319 SATA RAID Controller connectors. Since each drive’s array data
identifies itself to the array, it is possible to move or swap drives without
modifying the array setup. This is valuable when adding drives, or during a
rebuild.
