CAUTION!
●
Only remove a HDD module during operation if the drive is not
currently being accessed. Observe the control LEDs for the corre-
sponding HDD modules (see
“Indicators on the HDD module” on
page 47
).
●
Under no circumstances should you remove an HDD module while
the system is in operation if you are not sure whether the hard disk
drive is operated by a RAID controller and belongs to a disk array
which is operating at RAID level 1.
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.
If you want to remove an HDD module during operation, proceed as follows:
Ê
If you want to remove a HDD module that is not defective, the drive must be
first set to offline via the software (RAID controller configuration software).
Ê
Unlock the HDD module as described in section
“Unlocking the HDD
module” on page 64
.
Ê
Pull the HDD module out a few centimeters.
Ê
Wait for at least 60 seconds.
I
This period is necessary for the RAID controller to recognize that an
HDD module has been removed and for the hard disk drive to come
to a stop.
Ê
Pull the HDD module out completely.
