You prepare to replace a controller canister by verifying that the replacement controller canister has the correct FRU part number, backing up the configuration, and collecting support data. If the controller is still online, you must take it offline.
This task describes how to prepare to replace a controller canister in a controller shelf with two controllers.
Perform this task only if your storage array has two controllers.
MAC address: The MAC address for management port 1 (“P1”).
If you used DHCP to obtain the original controller's IP address, you
will need this address to connect to the new controller.
FRU part number: This number must match the replacement part
number for the currently installed controller.
If a problem occurs when you remove a controller, you can use the saved file to restore your configuration.
save storageArray dbmDatabase sourceLocation=onboard contentType=all file="filename";
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.
Execution environment requires setting JAVA_HOME environment variable, and JRE8 or later.
See Command Line Interface (CLI) Reference and follow the complete command syntax for this operation.
The file is saved in the Downloads folder for your browser with the name support-data.7z.

To use SMcli under system terminal:
For controller A: set controller [a] availability=offline;
For controller B: set controller [b] availability=offline;
Execution environment requires setting JAVA_HOME environment variable, and JRE8 or later.
