As a visual tool,
dxadmin uses icons to let the user trigger actions and to display information by changing the icon shape or color. The icons with all possible states are listed in the tables below.
Table A.1. Node or Adapter State
|Dolphin Network Manager has a valid connection to Dolphin Node Manager on the node.|
|Dolphin Network Manager cannot reach the node using TCP/IP, but Dolphin Express reports no additional problems.|
|The adapter is wrongly configured, broken or the driver is in an invalid state.|
|Dolphin Network Manager has detected that the adapter needs manufacturing information. Please contact Dolphin for upgrade.|
|Adapter has gone into a faulty state where it cannot read system interrupts and has been isolated by the Dolphin IRM driver.|
Table A.2. Link State
|Green pencil strokes indicates that the links are active. Fat active lines indicates x8 connections.|
|Red pencil strokes indicate that a link is inactive. Typically, a cable is unplugged, or not seated well.|
|Gray pencil strokes indicate that links have been disabled. Links are typically disabled when they are not in use. Thin green lines indicate active x4 connections.|
|A red dot (cranberry) indicates that a problem has occurred since the last check. The red dot will disappear if the problem was transient. You may run Diag (Diag -V 0, Diag -V 1 or Diag -V 9 differ in verbosity) from the Node menu to investigate the problem more closely. A red dot is also used to signal if a link has been trained to another PCI Express width than the user configured it to.|
|Yellow pencil strokes indicate that the link is in protected mode. It is probably in the process of becoming active, or the link training may have failed.|
The area at the top right informs about the current cluster status and shows settings of
dxadmin and the connected network manager. A number of settings can be changed in the Cluster Settings dialog that is shown when pressing the button.
Fabric status shows the current status of the fabric, UP, DEGRADED, FAILED or UNSTABLE (see below).
Check Interval DXadmin shows the number of seconds between each time the Network Manager sends updates to the Dolphin Admin GUI.
Check Interval Network Manager shows the number of seconds between each time the Network Manager receives updates from the Node Managers.
Topology shows the current topology of the fabric.
Fabric is UP when all nodes are operational and all links ok and therefore plotted in green.
Fabric is DEGRADED when some links operate at x4 in a x8 setup.
Fabric is REDUCED when all nodes are not reachable by ethernet, but we still have full connectivity for all reachable nodes. In the snapshot below jelen-03 is unreachable by ethernet, but all reachable nodes operate fully.
Fabric is in status FAILED if several links are broken in a way that breaks the full connectivity. In the snapshot below the cable connecting port 1 of Jelen-03 to port 0 of Jelen-04 is unplugged. Node jelen-03 and jelen-04 can not communicate via DX in this situation, and SuperSockets-driven sockets will have fallen back to Ethernet.
The fabric status is also set to FAILED if one or more nodes are dead as this node can not be reached via DX in a 2 node direct topology. The reason for a node being dead can be
Node is not powered up. Solution: power up the node.
Node has crashed. Solution: reboot the node.
The IRM low-level driver is not running. Solution: start the IRM driver like
> sc start dis_irm
The node manager is not running. Solution: start the node manager like
> sc start dis_nodemgr
The adapter is in an invalid state or is missing. Please check the node, and also consider the related topic in the Chapter 7, FAQ, .
The status of a node icon tells if a node is up, ethernet is out, or faulty, and a link is broken (red), disabled (grey) or up (green). When selecting a node you will see details in the Node Status area:
To get more information on the interconnect status for a node, get its diagnostics via
Serial number. A unique serial number given in production.
Adapter Type: The Dolphin part number of the adapter
Adapter number: The number of the adapter selected
DX Port 0: current status (active, protected, disabled or inactive) in addition to information about its partner. Partner is the entity that is connected on the other end of this link.
DX Port 1 current status and partner information.
