Raidtec FS3102 Hardware Installation Guide Version 1.0 30
NOTE: If write caching is enabled, data may be lost if power is removed prior to the data being written to the
disks. If write caching is enabled, a UPS or/and a BBU should be used in the system.
Auto Rebuild
The Raidtec FS3102 has 3 rebuild options if a RAID becomes degraded. These are disabled, priority and
background. These options can be set from Raidtec Manager. Background is the default setting. The RAID can
still be accessed during a rebuild, but performance will be reduced.
If a verify is scheduled when a rebuild is in progress, the verify will not take place.

Disabled

If Auto Rebuild is set to Disabled, the RAID will not rebuild unless the administrator manually selects Rebuild in
Raidtec Manager. If a RAID becomes degraded, an alert will still be generated even if Auto Rebuild is set to
disabled.

Priority

If Auto Rebuild is set to Priority, the RAID will rebuild as quickly as possible while still allowing reading and
writing to occur. Read and write performance may be substantially reduced from normal operation.

Background

If Auto Rebuild is set to Background, the RAID will rebuild, but priority will be given to normal read and write
operations. If there is a high level of read and write activity, the rebuild may take a long time.
