Activating and deactivating disk devices for IOPT

Activating disk devices for IOPT

IOPT_DEV_ADD activates logical devices for IOPT. The devices are then monitored by IOPT.

Once the program is started, messages are output via SYSOUT. The system awaits inputs from SYSDTA.

IOPT_DEV_ADD                                                                                                                                       

IOPT_DEV_ADD=ALL

IOPT_DEV_ADD=D-R(mn1,mn2)

ALL	All devices are activated for IOPT.
D-R(mn1,mn2)
	All devices with mnemonic names from mn1 to mn2 are activated. If mn1 and mn2 are identical, only one device is activated.

Deactivating disk devices for IOPT

IOPT_DEV_REM deactivates logical devices for IOPT. The devices are then not (no longer) monitored by IOPT.

IOPT_DEV_REM                                                                                                                                       

IOPT_DEV_REM=ALL

IOPT_DEV_REM=D-R(mn1,mn2)

ALL	All devices are deactivated for IOPT.
D-R(mn1,mn2)
	All devices with mnemonic names from mn1 to mn2 are deactivated. If mn1 and mn2 are identical, only one device is deactivated.

 

Querying activated devices

IOPT_DEV_ADD? outputs a list of all devices which were activated for IOPT using IOPT_DEV_ADD.

IOPT_DEV_ADD?                                                                                                                                     

IOPT_DEV_ADD?mask

mask	Complete or masked specification of a mnemonic device name. The following specifications are possible:
	*	All activated devices are listed.
	n*	All activated devices whose names begin with n are listed.
	nm*	All activated devices whose names begin with nm are listed.
	nml*	All activated devices whose names begin with nml are listed.
	nmlo	The device with the name nmlo is listed.
