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 SANtricity System Manager for the controller. (To
open the System Manager interface, point the browser to the controller’s domain name or IP address.)
Step 1: Place controller offline
The steps to place a controller offline depend on whether you have one controller (simplex) or two controllers
(duplex). Go to the appropriate instructions for:
•
Duplex: Place controller offline
• Simplex: Power down the controller shelf
Duplex: 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 database using SANtricity System Manager.
If a problem occurs during this procedure, you can use the saved file to restore your configuration. The
system will save the current state of the RAID configuration database, which includes all data for volume
groups and disk pools on the controller.
◦ From System Manager:
a.
Select Support
› Support Center › Diagnostics.
b. Select Collect Configuration Data.
c. Click Collect.
The file is saved in the Downloads folder for your browser with the name, configurationData-
<arrayName>-<dateTime>.7z.
◦ Alternatively, you can back up the configuration database by using the following CLI command:
save storageArray dbmDatabase sourceLocation=onboard contentType=all
file="filename";
