Example IECIOSxx parameters for hot I/O recovery

The following examples show how to specify the hot I/O recovery parameters in the IECIOSxx parmlib member. The values shown are also the IBM® default values.

HOTIO DVTHRSH=100    

• Specifies 100 repeated interrupts as the threshold for the operating system recognizing the condition.

HOTIO DFLT110=(BOX,)    

• For a non-DASD, non-dynamic pathing device. Box the device on the first occurrence of this condition. On recursion, prompt the operator.

HOTIO DFLT111=(CHPK,BOX)    

• For a DASD or dynamic pathing device that is not reserved. Attempt channel path recovery for the device on first occurrence of this condition. On recursion, box the device.

HOTIO DFLT112=(CHPK,OPER)    

• For a DASD or dynamic pathing device that is reserved. Attempt channel path recovery for the device on first occurrence of this condition. On recursion, prompt the operator.
