In answer to your rescue question see

Just substitute /dev/sda for /dev/hda

I doubt the bugzilla entry is relevant to you.  You at least have grub 
installed on /dev/sda since the system boots normally with both drives 
present.  If you followed my procedure correctly and did not get an 
error doing so, then you should also have a valid grub mbr on the second 
drive.

Before you put the system in production I recommend that you do test 
booting with only the second drive, and hit a cursor key at the grub 
menu to avoid booting the default if you get that far, then power down 
to re-connect the first drive.  That way you know the condition of your 
production system for handling a disk failure.
