Firmware update failed

[Mike-INM]

This is a brand new HPE Proliant ML350 Gen10 P/D P11053-001
I mounted the firmware update ISO (P19473_001_spp-2019.09.0-SPP2019090.2019_0905.39.iso) to a USB thumbdrive and booted from it. It reached the question asking automatic or interactive update and I chose automatic.
I got message:
Starting initrd...
Warning !!! Unable to mount the file system [cdrom]
Warning !!! Unable to mount the file system
Preboot maintenance mode
/bin/ash: can't accesstty: job control turned off
#

I am stuck here.
The firmware updates also fail from within Intelligent Provisioning. with message "Error: unexpectedly disconnected from boot status daemon.
Then Error: Invalid cluster:0
There is no way to update firmware.

Did you md5 check the ISO?

[Mike-INM]

Yes, I checked the MD5 Checksum

The UEFI image boots ok from the thumb drive. The program launches. It only fails on execution of the firmware update.

[Torsten.]

This is still before the update.
Do you have the advanced ILO license installed?

However, SPP 2019.09 has likely older firmware than your system.

Wait a day or two, get SPP2019.12, create an USB stick, boot from and select interactive.

What tool did you use to create the USB drive?

I have exactly the same "Error unexpectedly disconnected from boot status daemon?" after auto-update of firmware direct from HP, (without the cluster errors)

Sounds like a regression error, any suggestions gratefully accepted
