Removing a disk while the system remains available

The following procedure describes how to remove a disk using the hot-removability feature, which lets you remove the disk without turning the system off. This feature is only available on certain systems.

Hot removability is useful when you want to:

• Remove a disk that contains data in a separate non-rootvg volume group for security or maintenance purposes.
• Permanently remove a disk from a volume group.
• Correct a disk failure.
