Storage Drives Hot-Plug Conditions

The hard-disk drives (HDDs), solid-state drives (SSDs), and NVMe SSD drives installed in the server are hot-pluggable, but this capability depends on how the drives are configured. To hot-plug a drive you must be able to take the drive offline before you can remove it. When you take the drive offline, you prevent the operating system and any application from accessing the drive.

Caution  -  Data loss. Although the system can remain fully powered on, NVMe drives must be powered off using operating system commands before removal. Failure to do so can result in data loss and/or cause the operating system to crash.

The following conditions inhibit the ability to perform hot-plugging of a drive:

• The drive provides the operating system, and the operating system is not mirrored on another drive.

• The drive cannot be logically isolated from the online operations of the server.

If either of the above restrictions is true, then you must shut down the system before you replace the drive. See Powering Off the server.
