Where do you depend upon it being /dev/sda? I'd strongly recommend using
filesystem labels (change an existing ext2,3,4 filesystem label with e2label,
other FS have similar tools) and UUIDs for identifying drives/partitions in
config files. In /etc/fstab, you can use LABEL=foo or UUID=xxxxx where you
would normally use a path to the device; elsewhere (e.g. systemd units) you can
use a path such as /dev/disk/by-label/foo or /dev/disk/by-uuid/xxxxx.
Try to use non-ambiguous labels. If there's any chance of you mixing drives
from this machine and another, I would put e.g. the hostname into the label
(so your /boot is somehostname_boot and should you put this drive in another
machine to read it in the future, it won't clash with that machine's boot
partition label. Assuming you use different hostnames :))

Unless you have customized your grub config, they should automatically disappear
after you've removed those drives and re-ran update-grub2. It should also be
working off UUIDs rather than device names like /dev/sda too, mind...
