IC75218: DEDUPLICATED COPY STORAGE POOL IS NOT ELIGIBLE FOR SIMULTANEOUS WRITES, WHEN IT SHOULD BE

APAR status

• Closed as program error.

Error description

• When simultaneous writes is enabled for a deduplicated primary
  storage pool,
  and the copy storage pool is also deduplicated, the client
  backup will
  only write to the primary pool, instead of writing to both
  pools.
  There also has to be no client deduplication enabled in this
  scenario.
