Auxcopy job, one stream

I have an Auxcopy Source (HYperscale-X), destination (Hy7perscale). I have max numbers of readers set and multiple mount paths set on the Copy.

 

I have thousands of jobs in the Auxcopy, yet only one stream gets allocated. 

What am I missing?

If destination copy was not deduplicated, did it have combine to stream enabled? If so, it may have been set to 1?

Check:

  • # of readers on aux copy job/schedule
  • # of device streams on Storage Policy properties
  • Max parallel operations on each MA (usually wouldn’t be this unless there are hundreds of other jobs running on the same MA’s right now)

None of those. What I did notice is that the destination copy was not deduplicated (some one has set this up adhoc), when I repointed destination to same storage with deduplication the number of streams improved.
