Summary:
Issue


NetWoker 9.1.1.3 silon Multi-Streaming NDMP backups failing with Broken Pipe error
NDMP data backup succeeds but history index backup fails at the end with Broken Pipe error
History file backup fails, so NetWorker removes all successful NDMP data backup
Multi-Streaming is set via Client Parallesim and Action/group Parallelism values to 8.
Changing Action/group parallelism to 4 does not take effect and does not fix the issue (as per NetWorker NDMP user Guide Action/group parallelism should override Client Parallelism)

Error in policy logs:

Cause
The Client Application Information HIST parameter is set to HIST=Y or HIST=F.
Resolution
To fix this issue, change the HIST parameter in the Application Information field of the client resource to HIST=D (multi-streaming).
Here is from NetWorker NDMP User Guide 9.1:

Table 29 Isilon Application Information variables:
 HIST=F/D             Set this variable to F for Checkpoint Restart backups, to ensure the use of path based file history.
                                  Set this variable to D to enable concurrent streaming.
