Description
This display indicates the path status to any system for which a virtual circuit
exists. This display is available only on CI and DSSI based controllers.
Each position in the data field represents one of the possible nodes to which
the controller can communicate. To locate the path status for a given node,
use the column on the left to determine the high order digit of the node
number, and use the second row to determine the low order digit of the node
number. For CI controllers, the number of nodes displayed is determined by
the controllers MAX NODE parameter. The maximum supported value for
this parameter is 32. For DSSI controllers, the number of nodes is fixed at 8.
Each location in the grid contains a character to indicate the path status:
• A indicates only CI path A is functioning properly. In this example,
node 12 demonstrates this. This value is not displayed for DSSI based
controllers.
• B indicates only CI path B is functioning properly. In this example,
node 14 demonstrates this. This value is not displayed for DSSI based
controllers.
• X indicates the CI cables are crossed. In this example, node 27
demonstrates this. This value is not displayed for DSSI based controllers.
• A circumflex (^) indicates the single DSSI path or both CI paths are
functioning properly. In this example, nodes 8, 9, and 15 demonstrate
this.
• If a period (.) is in a position corresponding to a node, that node does not
have any virtual circuits or connections to this controller so either the
path status cannot be determined, or neither path is functioning properly.
• A space indicates the address is beyond the visible node range for this
controller.
