Error description
When submitting 2 tiering jobs to move vdisks between tiers for different SVC's using the same IBM Spectrum Control server, both jobs do not complete. The 1st job successfully moves vdisks as expected, but as soon as the 2nd tiering job is submitted no more vdisk copies are started for the 1st job and nothing is submitted for the second job.
Local fix
Submit only one tiering job at a time.

Problem conclusion
Temporary fix
The work around is submitting one tiering job at a time, and waiting for it to complete before submitting another tiering job.
