Storage Drives Hot-Plug Conditions

The hard-disk drives (HDDs), solid-state drives (SSDs), or NVMe SSD drives that are installed in the server are in most cases hot-pluggable. This capability depends on how the drives are configured and whether the drive is an NVMe device. To hot-plug a drive you must 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. For an NVMe storage drive, you must not only take the drive offline, but also power down the drive slot.

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.

  • The operating system does not support hot plug for the drive.

If any of these disk drive conditions are true, then you must shut down the system before you replace the drive. See Powering Down the Server.

Note -  Replacing a storage drive does not require removing the server from a rack.
