Symptoms

The following error message is received when trying to upgrade:

# system upgrade 6.2.1.30-663869.rpm
    ** This command is deprecated and will be unavailable in future releases.
    Use 'system upgrade start' or 'system upgrade precheck' instead.

    The 'system upgrade' command upgrades the Data Domain OS. File access
    is interrupted during the upgrade. The system reboots automatically
    after the upgrade.
    Are you sure? (yes|no) [no]: yes

    ok, proceeding.

    **** Upgrade failed: another upgrade is in progress.

Cause

This error only occurs on DD HA configurations. Network routing and HA code can affect peer node communication, causing RPC errors at running command-line interface (CLI). In the logs, entries such below are seen:

The CLI failures can be avoided if the HA peers are set up properly.

Resolution

  1. Verify that the HA pair is properly configured using a CIFS share or NFS export. Check for the following file and remove it:
/ddvar/lock/upgrade_lock
  1. Restart the update.
If the above steps do not address the issue, generate a Support Bundle and open a Technical Support case.
