Replacement disk RR4360S
There is a disk which is going to fail (Detected increasing reallocated sector count), Do need to shutdown the system RR4360S and swap the drive or are the drives hot swappable ?
Thanks, just curious to know during what situation we need to shutdown the array and replace, have read from one of the forums https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/Dead-volume-after-disc-replacement/td-p/1249309

Normally you don't (fwiw I never have).
What RAID mode are you using for the volume the failing disk is in?
The post you referenced has nothing to do with whether or not the NAS was shut down. No matter how you do it (power on or off), a replacement drive has to complete RAID sync. Depending on the RAID type, other failures during that process can kill the volume.
