The following statements can be used to specify base devices for DPAV. In VM2000 mode, the statements have to be entered in the monitor system.
Directly after loading the IORM subsystem, all base devices for DPAV are allowed/activated.
Activating base devices for DPAV
DPAV_BAS_ADD activates base devices for DPAV.
DPAV_BAS_ADD |
DPAV_BAS_ADD=ALL[,number][,vm-index] DPAV_BAS_ADD=D-R(mn1,mn2)[,number][,vm-index] |
ALL | All base devices are activated for DPAV. |
D-R(mn1,mn2) | |
All base devices with mnemonic names from mn1 to mn2 are activated. If mn1 and mn2 are identical, only one base device is activated. | |
number | |
Maximum number of alias devices for a specified base device. Default value: 7. | |
vm-index | |
Identifies a VM. | |
Special features in VM2000 operation:
When a VM index is specified, DPAV uses the base devices only for the guest system selected.
If no VM index is specified, DPAV uses the base devices for all guest systems.
Querying activated base devices
DPAV_BAS_ADD? displays a list of all base devices which are activated for DPAV.
DPAV_BAS_ADD? |
DPAV_BAS_ADD?mask |
mask | Complete or masked specification of a mnemonic device name. The following specifications are possible: | |
* | All activated base devices are listed. | |
n* | All activated base devices whose names begin with n are listed. | |
nm* | All activated base devices whose names begin with nm are listed. | |
nml* | All activated base devices whose names begin with nml are listed. | |
nmlo | The base device with the name nmlo is listed. | |
Deactivating base devices for DPAV
DPAV_BAS_REM deactivates base devices for DPAV.
DPAV_BAS_REM |
DPAV_BAS_REM=ALL DPAV_BAS_REM=D-R(mn1,mn2) |
ALL | All base devices are deactivated for DPAV. |
D-R(mn1,mn2) | |
All base devices with mnemonic names from mn1 to mn2 are deactivated. If mn1 and mn2 are identical, only one base device is deactivated. | |
