Control Path Failover (CPF)
The Scalar i6000 provides support for configuring the HP LTO-5
and later drive for control path failover. To configure a control
path failover drive, you must have a Storage Networking License
(SNW).
When control path failover is used, one drive is assigned as the
primary control path and another drive as the control path
failover (secondary) drive. The control path failover drive is used
whenever the primary control path drive fails or is inoperable.
Data path
One of the many possible paths that data can move over in the
storage area network environment, potentially involving many
components or connections between initiators and targets that
have been set since the initial configuration occurred.
Data path failover
You can use Data Path Failover to allow an alternate data path
when a preferred data path fails. Data Path Failover is provided
as part of the Storage Networking license and applies to HP
LTO-5 and later Fibre Channel tape drives only.
The HP LTO-5 and later Fibre Channel tape drives have two Fibre
Channel ports. If you enable Data Path Failover on the tape
drive, one port will be used as the "active port" for data
transmission, and the other port will stand by to be used if the
active port fails. If the tape drive loses its Fibre Channel link with
the active port,
it will automatically "fail over" and use the standby port to
continue drive operations.

Drive pooling
Drives to be held in a pool (or pools) of drives. You can specify
policy settings for the drive pools to configure how each pool
will react to a drive failure and load balancing.
Drive sled position
A slot where a Fibre Channel or SCSI drives reside in the control
module or expansion module in one of the two drive clusters.
