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 any application from accessing the drive and remove the logical
software links to the drive.
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 disk drive conditions is true, then you must shut down the system before you
replace the drive. See

Storage Drive Failure and RAID

A single storage drive failure does not cause a data failure if the storage drives are configured
as a mirrored RAID 1 volume (optional). The storage drive can be removed, and when a new
storage drive is inserted, the contents are automatically rebuilt from the rest of the array with no
need to reconfigure the RAID parameters. If the replaced storage drive was configured as a hot-
spare, the new HDD is automatically configured as a new hot-spare.
