An initialized condition means that a previous recovery action has successfully recovered the channel path and the channel path is available for use. This condition can be expected only. The initialized condition indicates that the channel subsystem has been successful in recovering the channel path to a state where it is again usable.
For devices that support the Dynamic Path Selection (DPS) feature, such as the 3380 Direct Access Storage and 3480 Magnetic Tape Subsystem, DPS validation is called to restore dynamic pathing arrays for each DPS device attached to that channel path. For each non-dynamic pathing device that does not support unconditional reserve and that had an outstanding reserve on the failing channel path, a reserve command is issued to the device. Any previously active I/O requests are restarted.
