HP B6960-96035 manual See also pre-exec

• COPY - The mirrored pair is currently re-synchronizing. Data is transferred from one disk to the other. The disks do not contain the same data.

• PAIR - The mirrored pair is completely synchronized and both disks (the primary volume and the mirrored volume) contain identical data.

	• SUSPENDED - The link between the mirrored disks is
	suspended. That means that both disks are accessed and
	updated independently. However, the mirror relationship is
	still maintained and the pair can be re-synchronized without
	transferring the complete disk.
parallel restore	Restoring backed up data to multiple disks at the same time (that
	is, in parallel) by running multiple Disk Agents, that receive data
	from one Media Agent. For the parallel restore to work, select
	data that is located on different disks or logical volumes and
	during backup, the data from the different objects must have
	been sent to the same device using a concurrency of 2 or more.
	During a parallel restore, the data for multiple objects selected
	for restore is read from media at the same time, thereby
	improving performance.
parallelism	The concept of reading multiple data streams from an online
	database.
physical device	A physical unit that contains either a drive or a more complex
	unit such as a library.
post-exec	A backup option that executes a command or script after the
	backup of an object or after the entire session completes.
	Post-exec commands are not supplied by Data Protector. You
	need to create your own. They can be written as executables
	or batch files on Windows and as shell scripts on UNIX.
	See also pre-exec.
pre- and post-exec	Pre- and post-exec commands are used to perform additional
commands	action before and after a backup or restore session. They are
	not supplied by Data Protector. You need to create your own
	commands. They can be written as executables or batch files
	on Windows and as shell scripts on UNIX.
prealloc list	A subset of media in a media pool that specifies the order in
	which media are used for backup.
