We got Proliant DL380 G9, when I try to eject or remove SAS HDD by taking it offline, the Red LED (Do not remove) is still on. I'm not really familiar with Proliant, on other servers I just take the drive offline and I can safely remove it. This one is not. If I take it out while Red Light is on Logical Drive with be corrupted. Below is screenshot of my drives, I wanted to remove Array B and C after it's full for backup purposes.
In addition, I am intending to use the server as file server. So if I am doing it wrong, please do kindly correct me and direct me to which is the right thing to do. The fplan is put 1tb as a file storage and we will be putting another 1tb to backup the files every week and when it's full it will be removed and replaced by another 1tb drive.
