Place controller offline (duplex)
If you have a duplex configuration, you must place the affected controller offline so you can safely remove the
failed HIC. You must back up the configuration and collect support data first. Then, you can take the affected
controller offline.
Before you begin
• Your storage array must have two controllers. The controller that you are not placing offline must be online
(in the optimal state).
• You have verified that no volumes are in use or that you have a multipath driver installed on all hosts
using these volumes.
• From SANtricity System Manager, you have verified the details in the Recovery Guru to confirm that you
have a failed HIC and to ensure no other items must be addressed before you can remove and replace the
HIC.
