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?

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.

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