The hard drives in the server are hot-serviceable, meaning that the drives can be removed and
inserted while the server is powered on.
Depending on the configuration of the data on a particular drive, the drive might also be
removable while the server is online. However, to hot-service a drive while the server is online
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-service 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.
