Changing the timeout value for the FC transport class

You can change the timeout value for the Fibre Channel (FC) transport class when the I/O operation stalls.

The FC transport class keeps all outstanding I/O for a certain time until it determines that the remote port is not responding. This time period is controlled by the timeout value. The default time is 60 seconds. This situation causes a temporary I/O stall in the case of FC link incidents or when paths are varied offline.

Change the timeout value.
