After replacing an HDD that has been combined into a RAID array, RAID
rebuild will be performed completely unattended as a background process.
▶
Ensure that the RAID array rebuild has started normally. Wait until the
progress bar has reached at least one percent.
▶
Inform the customer about the remaining rebuild time, based on the
displayed duration estimate.

CAUTION
The system is now operational, however, data redundancy will not be
available until the RAID array rebuild is complete. Depending on the
HDD capacity the overall process can take up to several hours, in some
cases even days.
