6.4. Replace DE2000H and DE4000H host interface card (HIC)
You can replace a host interface card (HIC) that has failed.
6.4.1. About this task
When you replace a HIC, you place the controller offline, remove the controller canister, install the
new HIC, replace the controller canister, and then bring the controller online.
6.4.2. Before you begin
•
Review
Requirements for DE2000H or DE4000H HIC replacement.
•
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.)
•
Make sure that no volumes are in use or that you have a multipath driver installed on all hosts
using these volumes.
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. If two controllers are present, each controller
must have identical HICs.
•
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.
•
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.)
6.4.3. Step 1: Place controller offline
If you have a duplex configuration, follow this step to place the controller offline so you can safely
remove the failed HIC.
Perform this task only if your storage array has two controllers (duplex
configuration).
Steps
1.
From the Details area of the Recovery Guru, determine which of the controller canisters has the
failed HIC.
2.
Back up the storage array’s configuration databaseusing ThinkSystem System Manager.
