- LIMITED_RECTIME=ss
- Specifies
the time in seconds to be used for certain IOS recovery functions.
Specify 0 seconds to disable the limited recovery time function. If
the limited recovery time function is disabled, IOS continues to use
it's pre-defined value to time the IOS recovery I/O requests. The
limited recovery time function is disabled by default.
Value Range: 2-14 (seconds)
- DEV=DASD|IOTIMING
- Specifies the devices that exploits the limited recovery time function. Valid options are all DASD devices or only devices that have the IOTIMING facility enabled.
- PATH_SCOPE={CU|DEVICE}
- Specifies whether the scope of the path recovery is for all devices
attached to the control unit (CU) or on a device-by-device basis (DEVICE).
Default: DEVICE
- PATH_INTERVAL=nnn
- Specifies the length of time to monitor for channel path errors
in minutes. This keyword can only be used when PATH_SCOPE=CU is specified
or when PATH_SCOPE=CU is the current value for the scope of the path
recovery.
Value Range: 1-10 (minutes)
Default: 10
- PATH_THRESHOLD=nnn
- Specifies the minimum number of channel path-related errors that
must occur every minute for the specified period of time (PATH_INTERVAL)
before IOS takes action. This keyword can only be used when PATH_SCOPE=CU
is specified or when PATH_SCOPE=CU is the current value for the scope
of the path recovery.
Value Range: 1-100 (errors)
Default: 10
DCCF=MESSAGE|WAIT_STATE
- Specifies the action that IOS-enabled interrupt processing will
take when a no-paths or intervention-required condition occurs on
a paging device. With the MESSAGE option, DCCF will be invoked to
issue the IOS115A WTOR. With the WAIT_STATE option, a non-restartable
wait state X'140' will be loaded.
IBM® recommends setting RECOVERY DCCF=WAIT_STATE in IECIOSxx to avoid the complexity of DCCF processing for the IOS115A WTOR message.
Default: MESSAGE
