DMO0012I DEVICE MANAGER DUMP COMPLETE DEVICE MANAGER feature DISABLED | ENABLED
Explanation
If the F DEVMAN,DUMP command
was used to obtain a dump of the device manager address space, DMO0012I
indicates that the dump is complete. If the operator MODIFY command
was used to request that a Device Manager feature be
ENABLED or DISABLED, DMO0012I displays the results. Supported features
can be displayed using the F DEVMAN,HELP command. The following features
are supported:
- REFVTOC
- When the REFVTOC feature is enabled and the system detects that the storage subsystem has expanded a volume, the system adjusts and rebuilds the VTOC index if appropriate to make the expanded space available to the system.
- DATRACE
- When the DATRACE feature is enabled, dynamic allocation trace data is produced when the REFVTOC function is invoked. DATRACE might be requested by the IBM® Support Center to obtain diagnostic data.
- REFUCB
- When the REFUCB feature is enabled the UCB will be automatically updated if necessary. When device support software detects that a DSS COPY or RESTORE or ICKDSF REFORMAT NEWVTOC operation has changed either the volser or the VTOC location, the DEVMAN REFUCB service will be invoked on each system in the sysplex that has REFUCB set to enabled. If the device is ONLINE, REFUCB will issue a VARY ONLINE, UNCONDITIONAL which will update both the volser and VTOC location in the UCB. If the device is OFFLINE, no action is taken.
- PPRCSUM
- When the PPRCSUM feature is enabled, the system issues message
IEA075I summarizing PPRC suspends for all devices in the control unit.
The system does not issue message IEA494I to display the state change
for each individual device.
When PPRCSUM feature is disabled, the system issues message IEA494I for PPRC state changes for each individual device individually rather than summarizing PPRC suspends for the entire control unit in an IEA705I message.
- QUERYFC
- Use with DISABLE keyword to allow all QUERYFC requests at one time when an ADRDSSU COPY is invoked. This is the default behavior that will not impose any limit to the number of QUERYFC requests at one time. It also resets the variables used by the enablement of the QUERYFC feature.
- QUERYFC:NUM
- Use only with ENABLE keyword, whree NUM(1-9999) represent a UNIT of work for Query FlashCopy® Capability (QUERYFC) requests at one time when an ADRDSSU COPY command is invoked.
- REFUCB
- When the REFUCB feature is enabled the UCB will be automatically updated if necessary. When device support software detects that a DSS COPY or RESTORE or ICKDSF REFORMAT NEWVTOC operation has changed either the volser or the VTOC location, the DEVMAN REFUCB service will be invoked on each system in the sysplex that has REFUCB set to enabled. If the device is ONLINE, REFUCB will issue a VARY ONLINE, UNCONDITIONAL which will update both the volser and VTOC location in the UCB. If the device is OFFLINE, no action is taken.
- PPRCSUM
- When the PPRCSUM feature is enabled, the system issues message
IEA075I summarizing PPRC suspends for all devices in the control unit.
The system does not issue message IEA494I to display the state change
for each individual device.
When PPRCSUM feature is disabled, the system issues message IEA494I for PPRC state changes for each individual device individually rather than summarizing PPRC suspends for the entire control unit in an IEA705I message.
System action
Processing continues.
Operator response
The requested feature is either COMPLETE, ENABLED or DISABLED.
