7.3.4 Replacing a 3.5-inch HDD module
V CAUTION!
● Only remove an HDD module during operation if the drive is not
currently being accessed. Observe the indicators for the
corresponding HDD modules, see "PRIMERGY TX120 S3 Server
Operating Manual".
● Under no circumstances should you remove an HDD module while
the system is in operation if you are not sure that the drive is operated
by a RAID controller and belongs to a disk array that is operating in
RAID level 1, 1E, 10, 5, 50, 6 or 60.
An HDD module can only be replaced during operation in conjunction
with a corresponding RAID configuration.
● All HDD modules (drives) must be uniquely identified so that they can
be reinstalled in their original mounting locations later. If this is not
done, existing data can be lost.
