what virtual SCSI controller type are you using for these VM's? Mine are 
'paravirtual'.

Also, what guest OS and VM hardware version is the guest running as?

Tris, John,

Thanks!

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.
