Transfer software files to the controllers

You transfer the software files to your controllers so you can begin the upgrade process. The components are copied from the management client to the controllers and placed in a staging area in flash memory.

1. Under ThinkSystem SAN OS Software upgrade, click Begin Upgrade.
   The Upgrade ThinkSystem SAN OS Software dialog appears.
2. Select one or more files to begin the upgrade process:
   1. Select the ThinkSystem SAN OS Software file by clicking Browse and navigating to the OS software file you downloaded from the Support web site.
   2. Select the Controller NVSRAM file by clicking Browse and navigating to the NVSRAM file that you downloaded from the Support site. Controller NVSRAM files have a filename similar to N2800-830000-000.dlp.

   These actions occur:

   • By default, only the files that are compatible with the current storage array configuration appear.
   • When you select a file for upgrade, the file's name and size appear.
3. (Optional) If you selected a ThinkSystem SAN OS Software file to upgrade, you can transfer the files to the controller without activating them by selecting the Transfer files now, but do not upgrade (activate upgrade later) check box.
4. Click Start, and confirm that you want to perform the operation.

   You can cancel the operation during the pre-upgrade health check, but not during transferring or activating.

5. (Optional) To see a list of what was upgraded, click Save Log.
   The file is saved in the Downloads folder for your browser with the name latest-upgrade-log-timestamp.txt.
