Servicing Storage Drives (CRU)

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 above drive restrictions is true, then you must shut down the system before you
replace the drive. See “Powering Down the Server” on page 51 .
Note - Replacing a storage drive does not require removing the server from a rack.
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 storage drive is automatically configured as a new hot-spare.
For instructions for configuring RAID on the server, refer to “Configuring Storage Drives for
Operating System Installation” in Oracle Server X6-2 Installation Guide .
Storage Drive Locations and Numbering
The following illustration and table show the locations of the HDD, SSD, and optional NVMe
SSD drives.
