Memory offlining in Superdome Flex fails for one of the memory blocks

I have a 8Socket HPE Superdome flex server which has SLES15 as its install base. I was verifying memory hot plug scenario in this system surprisingly memory offlining of one memory block belonging to each of the socket fails.

echo 0 > /sys/devices/system/node/node7/memory672/online

-bash: echo: write error: Invalid argument

Can I know what is happening here and why I am unable to make memory block 672 offline

Applogies for not updating this thread!

Looks like this is known issue in SUSE and the same has been confirmed by the vendor.
