Symptoms

A managed BIG-IP device upgrade task that installs a hotfix might fail on some devices with the error "Volume did not reach expected install state" while later examination of the target devices reveals that the installation succeeded.

Impact

The upgrade task cannot proceed on the failed device.

Conditions

Installing a hotfix requires first installing a base build, then installing the hotfix on top of that build. In some cases there is a longer than expected delay between the BIG-IP completing the base image installation and the BIG-IP beginning the hotfix installation. During this period, BIG-IP reports that the install is complete. BIG-IQ is monitoring the install status reported by BIG-IP, and if that status remains unchanged for too long, BIG-IQ concludes that the full install is complete, but also observes that the installed version (the base image) does not match the expected version (the hotfix).

Workaround

It may be possible to mitigate this issue by trying the upgrade task again, and possibly by reducing the processing load on the target system to reduce the time between the base image and hotfix installation. It's also possible to manually complete the upgrade by manually rebooting the target devices into the newly installed volume.
