Chapter 6. Host interface cards
6.1. Requirements for DE6000H HIC replacement
Before you add, upgrade, or replace a host interface card (HIC) in a DE6000H,
review the requirements and considerations.
6.1.1. Procedure overview
You can add, upgrade, or replace a HIC in the DE6000H (2U24) controller shelf and the DE6000H
(4U60) controller shelf.
The following is an overview of the steps to replace a HIC in a DE6000H controllers (DE6000H
(2U24) or DE6000H (4U60)):
1.
Take the controller offline
2.
Remove the controller canister
3.
Replace the battery
4.
Replace the controller canister
5.
Bring the controller online
6.1.2. Requirements for adding, upgrading or replacing a HIC
If you plan to add, upgrade, or replace a host interface card (HIC), keep the following requirements
in mind.
•
You must schedule a downtime maintenance window for this procedure. The power must be off
when you install HICs, so you cannot access data on the storage array until you have
successfully completed this procedure. (In a duplex configuration, this is because both
controllers must have the same HIC configuration when they are powered on.)
•
You must have two HICs that are compatible with your controllers.
For duplex configurations (two controllers), the HICs installed in the two controller canisters
must be identical. 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.
For information about compatible hardware, refer to
Lenovo Storage Interoperation Center
(LSIC) or Lenovo Press.
•
You have an ESD wristband, or you have taken other antistatic precautions.
•
You have a #1 Phillips screwdriver.
