protocols and upgrading the appliance, you can reference the white paper Best Practices for
Upgrading Oracle ZFS Storage Appliance.
■
Verify your current software version.

In the CLI, go to maintenance system updates and enter show.
■
Download the relevant software release. See Checking for and Downloading Software
Updates BUI, CLI.
