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 4
For the library, target-side data path monitoring is performed
automatically and proactively. The Datapath Conditioning dialog box
enables 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).
I/O blades must be present to access the Datapath
Conditioning dialog box.
