On checking /bootbank there is a large file HPE_SGH817S14C_2020-09-10_2020-11-10.ahs (73.7M)

What is this file? Is it safe to delete?

The bootbank is the partition your host boots from. There is another one (altbookbank) when you want to revert to an older installation. But the file is probably a log file for health info about your server (Active Health System/Server/Something). I think you can delete the file but keep a close eye on the partition and see if the file comes back.
