Description:
Reference FAQ that provides defintions and translation of Numeric values of the NDMP halt reasons.
These halt reasons are listed within the embedded trace (log context) for filer attached tape drives present within the netvault binary log for channel errors etc and are associated with backup or restore failures.
Use this FAQ to translate these states to determine the cause of failures.
This FAQ covers both ends of the NDMP data channel the source known as 'Data Server' and the target known as 'Data Mover'.
Example of binary log content:
DEVMGR 607 0 234244 Halted
DEVMGR 608 0 234244 State 4
DEVMGR 609 0 234244 Pause Reason 0
DEVMGR 610 0 234244 Halt Reason 5
DEVMGR 593 0 234244 oRequest is a 'NDMP_NOTIFY_MOVER_HALTED_POST'
DEVMGR 594 0 234244 Reason = 5
NDMP DATA HALT REASONS
halt_reason: This integer value identifies the event that caused the Data Server state machine to enter the HALTED state.
Valid halt reasons are defined by the ndmp_data_halt reason enumeration.
The halt reason MUST be set to NA when the Data Server state machine is initialized and MUST be set to NDMP_DATA_HALT_SUCCESSFUL, NDMP_DATA_HALT_ABORTED, NDMP_DATA_HALT_INTERNAL_ERROR, or NDMP_DATA_HALT_CONNECT_ERROR as appropriate upon transition to the HALTED state.
The halt reason MUST be set to NDMP_DATA_HALT_NA upon mover transition out of the HALTED state.
The halt reason is valid only when the Data Server is in the HALTED state.
Following a transition to the HALTED state, the Data Server MUST issue an NDMP_NOTIFY_DATA_HALTED message to identify the halt reason and allow the DMA to cleanup.
Transition to the HALTED state can result from expected or unexpected conditions. In progress Data Server operati
