1. LSISAS2208 RAID controller card: If no hot spare disk is configured, the RAID controller card can rebuild data on a new hard disk installed online to replace a faulty hard disk. (The new hard disk must be of the same specifications as the faulty hard disk.) However, if you remove and reinstall a hard disk that is not faulty, the LSISAS2208 RAID controller cannot identify the data on the hard disk. 2. LSISAS2308 RAID controller card: If you remove and install a hard disk without stopping services, the LSISAS2308 RAID controller card can identify data on the hard disk no matter whether the hard disk is new or not.
