Remove Failed Controller - Fujitsu ETERNUS AB Series Hardware Maintenance Manual

Procedure
1. Unpack the new controller canister, and set it on a flat, static-free surface.
Save the packing materials to use when shipping the failed controller canister.
2. Locate the MAC address and FRU part number labels on the back of the controller canister.
3. From SANtricity System Manager, locate the replacement part number for the controller canister you are
replacing.
When a controller has a fault and needs to be replaced, the replacement part number is displayed in the

a) Select Hardware.

the replacement controller.
Attention: Possible loss of data access – If the two part numbers are not the same, do not
attempt this procedure. In addition, if the failed controller canister includes a host interface card
(HIC), you must install that HIC into the new controller canister. The presence of mismatched
controllers or HICs causes the new controller to lock down when you bring it online.

offline, a SANtricity System Manager Unavailable message is displayed. Select Connect to an alternate
network connection to automatically access SANtricity System Manager using the other controller.
