The drives (HDDs and SSDs) are hot-pluggable, meaning that the drives can be removed and inserted while the server is powered on.
To hot-plug a drive you must take the drive offline before you can safely remove it. Taking a drive offline prevents any applications from accessing it, and removes logical software links to it.
You cannot hot-plug a drive in the following situations:
If the drive contains the operating system and the operating system is not mirrored on another drive.
If the drive cannot be logically isolated from the online operations of the server.
If either of these conditions apply to the drive being serviced, you must take the server offline (shut down the operating system) before you replace the drive.
If the drive is owned by a specific logical domain, stop that logical domain.
For information about stopping logical domains, refer to the Oracle VM Server for SPARC Administration Guide at:
