Working With Data Path Conditioning
The Scalar i6000 provides an automatic means of verifying, monitoring,
and protecting data path integrity between hosts and library drives. This
feature is referred to as data path conditioning. Using this feature,
administrators can proactively detect and resolve data path problems
before they affect backup, restore, and other data transfer operations.
Data path conditioning ensures that data transmissions are optimized
and reliable, resulting in improved system availability.
The FC I/O blade manages data path conditioning along the path
between itself and the library drives. Data path monitoring
automatically occurs at regular, configurable intervals. The I/O blade
generates a RAS ticket if monitoring tests fail for two intervals. This
indicates either loss of connectivity or drive failure. The FC I/O blades
include the data path conditioning feature, and administrators can
configure it using the LMC.
Configuring Datapath
Conditioning
For the library, target-side data path monitoring is performed
automatically and proactively. The Datapath Conditioning dialog box
allows you to set the level at which the data path is monitored between
an I/O blade and the drive(s) connected to it. You also can set the time
interval between monitoring checks (up to 48 hours).
Note: I/O blades must be present to access the Datapath
Conditioning dialog box.
