Update-OVServerFirmware -firmwareinstallmode firmwareonly requiring server power off in error

[danthomasbbc]

Expected Behavior

From the documentation:
HPE OneVIew PS 8.50
Update-OVServerFirmware
-FirmwareInstallMode
Specify the Firmware Baseline Policy mode. Avialable options are:

• FirmwareOnly - Updates the system firmware without powering down the server hardware using using HP Smart Update Tools.
• FirmwareAndSoftware - Updates the firmware and OS drivers without powering down the server hardware using HP Smart Update Tools.
• FirmwareOffline - Manages the firmware through HPE OneView. Selecting this option requires the server hardware to be powered down.

If task is done via the GUI, then the relevant jobs are applied/queued as expected. Running the job with -FirmwareAndSoftware completes successfully whilst the server is powered on. However, running with '-FirmwareOnly' returns an error for the server not being powered off.

Actual Behavior

C:\Users\tec-fl-dt1> Update-OVServerFirmware -InputObject $OVListHosts -Baseline $targetbaseline -firmwareinstallmode firmwareonly
Update-OVServerFirmware: The provided server resource ################ is not powered off.  Server power state must be off before attempting to install an offline firmware bundle.
