Storage Management White Papers
Consistent FlashCopy of LVM Mirrored Applications
Overview Many applications running on AIX are mirroring their data using the Logical Volumes Manager (LVM). Purpose of the mirror is to provide redundancy in order to continue with operation in case of a failure in the storage environment. The mirrors are usually allocated in physically different storage subsystems, to ensure that the application will continue when one storage subsystem fails. The LVM will recognize the failure of the mirror. Receiving write request will be applied to the remaining mirror. At the same time the LVM marks the changed physical partitions for the failing mirror as 'Stale'. This ensures that the mirror can be resynchronized when the failing storage subsystem will be available again.
