6.3. Upgrade DE2000H and DE4000H host interface card
(HIC)
You can upgrade a host interface card (HIC) in a DE2000H or DE4000H array to
increase the number of host ports or to change host protocols.
6.3.1. About this task
When you upgrade the HICs, you must power off the storage array, remove the existing HIC from
each controller, install a new HIC, and reapply power.
6.3.2. Before you begin
• Review
Requirements for DE2000H or DE4000H HIC
• 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.)
What you'll need
• One or two HICs, based on whether you have one or two controllers in your storage array. The
HICs must be compatible with your controllers.
• Labels to identify each cable that is connected to the controller canister.
• An ESD wristband, or you have taken other antistatic precautions.
• A #1 Phillips screwdriver.
• Any new host hardware installed for the new host ports, such as switches or host bus adapters
(HBAs).
• All cables, transceivers, switches, and host bus adapters (HBAs) needed to connect the new
host ports.
For information about compatible hardware, refer to
(LSIC) or Lenovo Press.
• A management station with a browser that can access ThinkSystem System Manager for the
controller. (To open the System Manager interface, point the browser to the controller's domain
name or IP address.)
6.3.3. Step 1: Prepare to upgrade host interface cards
Prepare to upgrade host interface cards (HICs) by backing up the storage array's configuration
database, collecting support data, and stopping host I/O operations. Then, you can power down
the controller shelf..
