Hardware problems 63
Action:
HP recommends that you access drive data only when the same RAID or non-RAID mode is enabled. Back up
and restore the data on the drives.
The Smart Array controller does not show logical drives after moving drives to a new
server or JBOD
Action:
A drive migration issue has occurred. Be sure to follow all drive roaming rules when migrating drives. See
"Drive roaming (on page 63)."
Drive roaming
Drive roaming lets you move disk drives and arrays while maintaining data availability. You can move one
or more disk drives in a configured logical drive to a different bay position as long as the new bay position
is accessible by the same controller. In addition, you can move a complete array from one controller to
another, even if controllers are in different servers. The logical drive status must be good before you move
physical drives to a new bay position.
Drive roaming is an offline feature. There is no method for removing an array while the server is online and
then moving it to a new physical location.
Expansion board problems
System requests recovery method during expansion board replacement
When replacing an expansion board on a BitLocker™-encrypted server, always disable BitLocker™ before
replacing the expansion board. If BitLocker™ is not disabled, the system requests the recovery method
selected when BitLocker™ was configured. Failure to provide the correct recovery password or passwords
results in loss of access to all encrypted data.
Be sure to enable BitLocker™ after the installation is complete.
For information on BitLocker™, see BitLocker™ for Servers on the Microsoft website
(http://www.microsoft.com).
