Automatic Data Recovery - Compaq Smart Array 221 User Manual

Automatic Data Recovery

After you replace a failed drive, automatic data recovery reconstructs the data
and places it on the replaced drive. This allows a rapid recovery to full operating
performance without interrupting normal system operations.
In general, the time required for a rebuild is approximately 15 minutes per GB.
The actual rebuild time, however, is dependent upon the Rebuild Priority set, the
amount of I/O activity occurring during the rebuild operation, the number of
drives in the array (RAID 5) and the disk drive speed.

CAUTION: You must specify RAID 5 or RAID 1 through the Array
Configuration Utility to make the recovery feature available. The
drive failure alert system and automatic data recovery are
functions of the Smart Array 221 Controller; they operate
independently of the operating system.
