Requirements for adding, upgrading or replacing a HIC

Place controller offline (duplex)

If you have a duplex configuration, you must place the affected controller offline so you can safely remove the
failed HIC. You must back up the configuration and collect support data first. Then, you can take the affected
controller offline.
Before you begin
• Your storage array must have two controllers. The controller that you are not placing offline must be online
(in the optimal state).
• You have verified that no volumes are in use or that you have a multipath driver installed on all hosts
using these volumes.
• From SANtricity System Manager, you have verified the details in the Recovery Guru to confirm that you
have a failed HIC and to ensure no other items must be addressed before you can remove and replace the
HIC.
About this task
Perform this task only if your storage array has two controllers (duplex configuration).
Procedure
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.
If a problem occurs when you remove a controller, you can use the saved file to restore your configuration.
a) Open the Enterprise Management Window (EMW) for SANtricity System Manager on your management
station.
b) Select the storage array.
c) Select Tools > Execute Script.
d) Type the following command in the text box.
save storageArray dbmDatabase sourceLocation=onboard contentType=all
file="filename";
In this command, filename is the file path and file name to which you want to save the database.
Enclose the file name in double quotation marks (" "). For example:
file="C:\Program Files\CLI\logs\dbmdata.zip"
This command does not automatically append a file extension to the saved file. You must specify a file
extension when entering the file name.
e) Select Tools > Verify and Execute.
3. Collect support data for your storage array using SANtricity System Manager.
a. Select Support > Support Center > Diagnostics.
b. Select Collect Support Data.
c. Click Collect.
The file is saved in the Downloads folder for your browser with the name support-data.7z.
4. If the controller is not already offline, take it offline now using either SANtricity System Manager or the
Enterprise Management Window's (EMW) script editor:
• To use SANtricity System Manager:
a. Select Hardware.
b. If the graphic shows the drives, select Show back of shelf to show the controllers.
c. Select the controller that you want to place offline.
