Storage Drives Hot-Plug Conditions

The solid-state drives (SSDs) or hard-disk drives (HDDs) 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 any application from accessing the
drive and remove the logical software links to the drive.
The following situations 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 drive restrictions is true, then you must shut down the system
before you replace the drive. See
Note – Replacing a drive does not require removing the server from a rack.
