Yes, I have verified that the rescan script in 15.3 works with the "-a" flag as far as discovering newly added devices. This script originally discovered new and removed devices with no "-flags". It appears now that in order for it to work as it did originally you must pass not only the "-a" but the "-r" flag also. The "-r" flag removes removed devices from the list displayed by the "lsscsi -g" command. Yes, you can close this bug now. Thank you.
