Creating a Snapshot of Files on a C Series Controller
You can create one or more snapshots of the system software to serve as a backup. When you create a snapshot, the software backs up the operating system and the SRC software to a partition on the C Series Controller. You can restore the files in a snapshot to the system software if needed.
To create a snapshot of the system software:
Verify which version of the software is running on the system.
When you issue the show system information command in a virtualized SRC software, the manufacturer, version, and serial number details are not displayed in the output. In addition, the product name is displayed as vSRC.
user@host> show system information
Enter the request system snapshot command. Use the verbose option to view information about the snapshot process.
