Because the E2860 controller shelf has two E2800 controllers, you can replace one of the controllers
while your appliance is powered on and performing read/write operations, as long as the following
conditions are true:
• The second controller in the shelf has Optimal status.
• The “OK to remove” field in the Details area of the Recovery Guru in SANtricity System
Manager displays Yes, indicating that it is safe to remove this component.
Attention: If the second controller canister in the shelf does not have Optimal status or if the
Recovery Guru indicates that it is not OK to remove the controller canister, contact technical
support.
When you replace a controller, you must remove the battery from the original controller and install it
in the replacement controller.
Note: The E2800 controllers in the appliance do not include host interface cards (HIC).
Steps
1.
Unpack the new controller, and set it on a flat, static-free surface.
Save the packing materials to use when shipping the failed controller.
2. Locate the MAC address and FRU part number labels on the back of the replacement controller.
Label
Label Description
1
MAC address The MAC address for management port 1 (“P1”). If you
used DHCP to obtain the original controller's IP address,
you will need this address to connect to the new controller.
2
FRU part number The FRU part number. This number must match the
replacement part number for the currently installed
controller.
3. Prepare to remove the controller.
You use SANtricity System Manager to perform these steps. As needed for additional details,
reference the E-Series instructions for replacing the E2800 controller.
a. Confirm that the replacement part number for the failed controller is the same as the FRU part
number for the replacement controller.
When a controller has a fault and needs to be replaced, the replacement part number is
displayed in the Details area of the Recovery Guru. If you need to find this number manually,
you can look on the Base tab for the controller.
Attention: Possible loss of data access – If the two part numbers are not the same, do not
attempt this procedure.
