The command required is:

show upgrade package

The storage O&M section distinguishes current-version inspection from upgrade-package and historical-version management. For the current running version, the Training Materials explicitly instruct the administrator to log in to the CLI as a super administrator, run show system general, and check Product Version.

Historical upgrade information is associated with the software upgrade/package subsystem rather than the general system-information query. Therefore, show upgrade package is used to display information about storage-system upgrade packages and the historical software-version information retained by the system.

This distinction is operationally important. show system general tells the engineer what software version is currently active, whereas show upgrade package is used when examining the upgrade history/package information maintained by the controller environment. Huawei's O&M course also treats controller upgrades as a controlled lifecycle process involving imported upgrade packages, pre-upgrade inspection, upgrade execution, and result verification.
