Host interface cards

A host interface card (HIC) can optionally be installed within a controller canister. The AB6100 controller
includes host ports on the optional HIC. Host ports that are built into the HIC are called HIC ports.

Overview and Requirements

If you plan to add, upgrade, or replace a host interface card (HIC), keep the following requirements in mind.
• You have scheduled a downtime maintenance window for this procedure. You cannot access data on the
storage array until you have successfully completed this procedure. Because both controllers must have the
same HIC configuration when they are powered on, the power must be off when you install HICs.
Attention: The presence of mismatched HICs causes the controller with the replacement HIC to
lock down when you bring it online.
• You have all cables, transceivers, switches, and host bus adapters (HBAs) needed to connect the new host
ports.
• You have an ESD wristband, or you have taken other antistatic precautions.
• You have a #1 Phillips screwdriver.
• You have labels to identify each cable that is connected to the controller canister.
• You have installed SANtricity System Manager on a management station, so you can use the storage
array's command line interface (CLI).
If SANtricity System Manager has not yet been installed, follow the instructions in the
configuration, Windows express
the software.
This section describes how to prepare to replace a host interface card in the following controller shelves:
• AB6100 controller shelf

Add host interface cards

You add host interface cards (HICs) to increase the number of host ports in your storage array and to provide
additional host protocols.
About this task
• When you add HICs, you must power off the storage array, install the HIC, and reapply power.
• When adding HICs to an AB6100 controller repeat all steps to remove the second controller, install the HICs
for the second contoller, and reinstall the second controller before reapplying power to the controller shelf.
Attention: Possible loss of data access – Never install a HIC in an AB6100 controller canister if that
HIC was designed for another ETERNUS AB controller. In addition both controllers and both HICs must
be identical. The presence of incompatible or mismatched HICs causes the controllers to lock down
when you apply power.

Place controller offline

You must place the controller shelf offline so you can safely add or upgrade the HICs. You must back up the
configuration and collect support data first. Then, you can take the controller shelf offline.
Before you begin
• You have scheduled a downtime maintenance window for this procedure. You cannot access data on the
storage array until you have successfully completed this procedure. Because both controllers must have the
same HIC configuration when they are powered on, the power must be off when you install HICs.
