Change of physical drives in a proxmox server

[wago80]

HI. I have a Proxmox server installed in a dual CPU server. The Proxmox itself is installed in a SSD drive and, as storage, I have a 2 TB, 3.5" mechanical SATA drive.
The storage of the 2 TB HD started to fill up, so I decided to change it for two 3.5" SATA HDs of 8TB each.
What I did so far is to add one of the 8 TB drives and clone all the LCX and VMs, on the 2 TB drive, to the new 8tb drive. I leave the LCX and VMs on the 2 TB drive powered off and all the LCX and VMs copied to the 8 TB drive powered on and working fine.
What I would like to know is how do I disconnect the 2 TB drive safely in order to add the second 8tb drive (the server case only have space for two 3.5" HDD).
For what I know, I should go to the "Datacenter" section of the web console, then go to "Storage", then select the 2 TB drive and push the "Remove" button. Then I should power off the server, remove the 2 TB Drive and install the second 8 TB drive. Is that correct? That's the safest procedure to change the drives?
Thank you all in advance for your time and kind answer.

You probably should first remove those (source) LXCs & VMs - as PVE is going to complain that the underlying storage is missing for them. You may not (probably) even be able to remove that 2TB storage as long as Proxmox sees that LXCs & VMs have disks on that drive storage.
