CODE EXAMPLE 10-2 Output for Sun StorEdge A5200 Array:
Note – Sun StorEdge Traffic Manager is not supported for use with the Sun
StorEdge A3500FC array.
In the previous code examples, Path Class indicates either primary or secondary.
Primary path is used for I/O operations. The secondary path is not used for active
I/O unless a failover happens. The Sun StorEdge T3 array has both a primary and
secondary path class. The Sun StorEdge A5200 array has two primary paths, if it is
dual connected. Both primary paths are used for active I/O.
Path State indicates ONLINE, STANDBY, or OFFLINE. Active I/O travels down
ONLINE paths only. STANDBY paths indicate paths that are waiting for I/O in the
event of a failover operation. OFFLINE paths indicate no I/O can travel down the
