Chapter 3: Configuring Your LibraryWorking With Data Path ConditioningQuantum Scalar i6000 User’s Guide 243Working With Data Path ConditioningThe Scalar i6000 provides an automatic means of verifying, monitoring,and protecting data path integrity between hosts and library drives. Thisfeature is referred to as data path conditioning. Using this feature,administrators can proactively detect and resolve data path problemsbefore they affect backup, restore, and other data transfer operations.Data path conditioning ensures that data transmissions are optimizedand reliable, resulting in improved system availability.The FC I/O blade manages data path conditioning along the pathbetween itself and the library drives. Data path monitoringautomatically occurs at regular, configurable intervals. The I/O bladegenerates a RAS ticket if monitoring tests fail for two intervals. Thisindicates either loss of connectivity or drive failure. The FC I/O bladesinclude the data path conditioning feature, and administrators canconfigure it using the LMC.Configuring DatapathConditioningFor the library, target-side data path monitoring is performedautomatically and proactively. The Datapath Conditioning dialog boxallows you to set the level at which the data path is monitored betweenan I/O blade and the drive(s) connected to it. You also can set the timeinterval between monitoring checks (up to 48 hours).Note: I/O blades must be present to access the DatapathConditioning dialog box.1 Log on as an administrator.2 Make sure that you are viewing the physical library. From the Viewmenu, click the name of the physical library.3 Click Setup > Blades > Connectivity > Datapath Conditioning.The Datapath Conditioning dialog box appears, showing all the I/Oblades found in the library. Each blade is identified by name and bygeographic location.
