Sometimes after a hard reboot (power cut), if your synology cannot be logged in with DSM and it shows "System is getting ready. Please log in later" , please do these steps :

#Admin login via ssh
> synobootseq --set-boot-done
> synobootseq --is-ready
#optional
> /usr/syno/etc/rc.d/S97apache-sys.sh start
> /usr/syno/etc/rc.d/S95sshd.sh start
