I blew away the original VM I was using for testing as it came time to do the things for real in production - and, as much as I hated it, I just added the disk and rebooted the production machine to make it "see" that disk. However, I have then decided to investigate the matter further. So I created a new one. It is running on an ESXi 5.5 server, VM Version 10, VMware Paravirtual SCSI controller, configured for RedHat 6/64-bit OS, running Centos 6/64 bit. And it worked perfectly when it came to "seeing" a hotplugged disk drive. So I am not sure what to make of all of it - but it looks like freshly created VM's are OK and it was indeed something to do with the VM settings. Cheers, Boris.
