Replace a Failed Storage Controller
Replace a failed storage controller with a replacement storage controller.
Prerequisite
CAUTION: Do not power down both storage controllers. The other storage controller continues to operate when the failed
storage controller is powered down. If both storage controllers are mistakenly powered down, restart the storage system before
replacing the failed storage controller.
About this task
The cover of the storage controller indicates which slot the storage controller operates in.
Storage controller 1 goes into the top slot.
Storage controller 2 goes into the bottom slot.
Steps
1 Make sure that all cables plugged into the storage controller are labeled.
2 Disconnect the cables from the failed storage controller.
3 Remove the failed storage controller from the chassis.
CAUTION: To prevent a thermal shutdown of the storage system, the service bae must be installed within three minutes
of removing the storage controller.
4 Install the service bae into the empty slot in the chassis.
5 Perform the following on the failed storage controller:
a Remove the cover from the storage controller, and set it aside.
The label on the cover identies the chassis slot from which the failed storage controller was removed.
b Remove the I/O card, mezzanine card, and battery backup unit from the failed storage controller.
The I/O card, mezzanine card, and battery backup unit are reinstalled in the replacement storage controller.

a Remove the cover from the storage controller.
b Insert the I/O card, the mezzanine card, and battery backup unit into the storage controller.
7 Take the cover from the failed storage controller, and install it on the replacement storage controller.
The label on the cover identies the correct chassis slot for the replacement storage controller.
8 Remove the service bae from the chassis.
CAUTION
: To prevent a thermal shutdown of the storage system, the storage controller must be installed within three
minutes of removing the service bae.
9 Install the replacement storage controller in the chassis.
10 Reconnect the cables to the storage controller.
The storage system reads conguration information from the disks, and the storage controller is updated to the same version of
software that is running on the existing storage controller.
NOTE
: If the Storage Center software on the storage controller is older than the software on the existing storage controller,
the storage system updates the storage controller with the software version on the existing storage controller. The Storage
Center software update on the storage controller could take 15 to 45 minutes to complete.
11 Clear the storage controller swap status from the Hardware tab in Dell Storage Manager.
For instructions, see the Storage Manager Administrator’s Guide.
