CMMVC8304E: The system cannot apply the task because an earlier drive update task is still in progress.

Explanation

There is an existing svctask applydrivesoftware already running, and only one is allowed at a time.

User Response

Try the command again when there is no drive update task in progress. Either use the lsdriveupgradeprogress command to determine when the updates will be completed, or use svctask applydrivesoftware -cancel to cancel the current drive update task.
