CAUTION: If the server is set up in an array configuration and an active drive is replaced
while the system is powered down, the following POST drive error message (1786) occurs
when the system is powered up:
PRESS <F1> TO BOOT THE SYSTEM AND REBUILD THE REPLACED
DRIVE, OR PRESS <F2> TO BOOT THE SYSTEM WITHOUT REBUILDING
THE DRIVE(S).
Pressing the F2 key causes permanent data loss to the logical drive. The F2 key should be
pressed only when all the drives are replaced or when complete data loss is desired.
CAUTION: Hard drives must be reinserted in the same locations from which they were
removed. Reinserting hard drives in different orders and locations may result in data loss.
