6.2.3. Step 1: Prepare to add HIC
Prepare to add the HIC 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..
Steps
1. From the Home page of ThinkSystem System Manager, ensure that the storage array has
Optimal status.
If the status is not Optimal, use the Recovery Guru or contact technical support to resolve the
problem. Do not continue with this procedure.
2. Back up the storage array's configuration database using ThinkSystem System Manager.
If a problem occurs when you remove a controller, 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 ThinkSystem System Manager:
a. Select Support › Support Center › Diagnostics.
b. Select Collect Configuration Data.
c. Click Collect.
The file
the name,
*configurationData-<arrayName>-<dateTime>.7z*.
◦ Alternatively, you can back up the configuration database by using the following CLI
command:
a. Download SMcli from ThinkSystem System Manager and set up SMcli command
execution environment.
b. Execute
the
sourceLocation=onboard contentType=all file="filename";
In this command, filename is the file path to which you want to save the database.
Enclose the file name in backslash following 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.
Notes:
▪ Under PowerShell, enclose the file name following two quotation marks(""), for
example, file=\""data.zip\"".
▪ Execution environment requires setting JAVA_HOME environment variable, and
JRE8 or later.
